| 评述: | 呵呵,我就是张先生,使用了两周了,非常好.LOBO人爽快,东西也好,烧得温度也高,难得的好
烧友,多交流. 收集了一些资料供LOBO和其他同好参考.个人使用下来主要感受是,瞬态更好,能量分布更均 衡,更接近真实乐器,音色温暖但是不失细节,乐感很好,系统可以提升一个档次. 1,关于原理和材料使用,据说是来自原厂说明书,我从网络上找来的 “Hydra was not designed to filter power, or to act as a surge suppressor. It adheres to two fundamental design goals: providing power distribution for multiple components, and most importantly, to achieve an unparalleled level of performance in high-end AV systems. From the first note to the last, Hydra delivers music with a previously unachievable sense of truth, purity and absolute dynamic power. Hydra operates on a completely different theory than conventional power products. Most power line devices are designed to either impede instantaneous current flow (current limiting) or to redirect current flow (current dumping). Several years of investigation at Shunyata Research indicates that these practices degrade dynamic reproduction and introduce subtle distortions that are all too evident when listening or viewing. The HYDRA does not employ any conventional capacitors or current limiting devices that degrade performance. Hydra utilizes the revolutionary, patent pending Stardust technology found in PowerSnakes AC power cables. Stardust is a proprietary compound that reduces noise through an electromagnetic coupling mechanism. Its operation is entirely passive and does not require any physical electrical connection to the conductors.Hydra improves the effectiveness of the Stardust compound by employing a proprietary element called the ElectroMagneticLens (EML). The EML consists of a Stardust chamber with a field-shaping bus-array that polarizes the electromagnetic field, focusing high-frequency energy in a bi-polar pattern. This polarization achieves a two-fold improvement in the absolute coupling of the EM field and the Stardust compound. The result is a reduction in high frequency noise without producing the compressive side effects of conventional capacitors, transformers and chokes! The EML is electro magnetically shielded within a precision, internal aluminum chassis that is fabricated to a tolerance of less than two thousandths of an inch. Hydra employs extensive vibration dampening materials, including side panels of quarter inch natural granite and external panels of anti-resonant high-density polymers 2,一个测评 So now we come to the Shunyata Research Hydra. A product out of the third path, the Hydra uses no transformers, chokes, filters, regenerators, coils or capacitors, instead it relies on a completely passive design built to ultra- high standards, using hyper-pure components, unique topologies and exotic materials based on Caelin Gabriel's (the head of Shunyata Research) background in materials science. Gabriel, whose training is in quantum physics, spent a decade working at the National Security Agency developing low-level signal acquisition devices (I am not sure how you read that, but I take it to mean eavesdropping bugs with extreme sensitivity). After leaving the employ of the government Gabriel worked in the computer industry, designing gigabit and beyond network data transmission devices. Both these environments are extremely rugged proving grounds, where the tolerances, electrical hazards and technology are magnitudes beyond even the most sophisticated of audio environments. The first and most obvious face the Hydra presents is its exceptional build quality. A 35 pound 10" wide by 6" tall and 14" block, the sides are finished with half inch thick, polished and dampened granite while the face has a solid Amaranth wood inlay. The rest of the unit is covered with a mirror-polished polymer. It is a beautiful thing that is not afraid of showing it. Round back are found six, Hubbel, hospital-grade outlets, arrayed in three individually isolated pairs. The power cord uses a Nema twist-lock connector, assuring a tight grip. From the factory, Hydra uses the Hydra cord (which is based on their Sidewinder Gold cord), but can be upgraded to any power cord in the Shunyata line. Also on the back is a 20-amp fuse. With a max output of 2,500 watts, a single Hydra has enough pop for all but the most esoteric of systems. Internally the Hydra uses high purity, massive CDA-101 copper buss bars to distribute and "focus" power. That focusing action is a significant part of the Hydra. According to their literature FeSi-1000 (a proprietary compound that functions similar to ferrites but uses a different coupling mechanism to attenuate and dissipate radiated electrical energy) is used in their EML, or Electro-Magnetic Lens. The EML is a buss array, designed using antenna array principles and contained with an aluminum structure acting as a magnetic shield, which "...create(s) a polarized electromagnetic field. This effectively focuses high energy between two conductive plates. The EML concentrates high frequency EMI, thereby improving the effective coupling of the FeSi-1000 compound". A second, significant part of the Hydra design is the massive case described earlier. Shunyata has paid exacting attention to resonance control, and, as my sore knuckles can attest to, this thing is solid. Finally, with a ten year, transferable warranty, the Hydra is built like no other power conditioner that I know of. Besides being solid, this thing is meant to last. Much has been made of the build quality of the Hydra in various online forums and in other reviews. I personally find it odd that, as long a product sounds right, anyone would attack it because it is overbuilt. Give me a product designed to last over one designed to last until the day after the warranty expires any time. 3,继续评测 Shunyata Research Hydra Power-Distribution Center by Bill Cowen "Simply improves the sound in all respects." Review Summary Sound "A dramatic improvement in soundstage space and detail" along with "bass lines [that] were stronger, with greater impact and heft," but "no smoothing, no reduction in treble energy or extension, no loss of bass impact, and no loss of dynamic swing" either; in the end, "what [Bill] got was more of the music, and less of the non-music." Features Six outlets and 1875-watt power limit, so it will accommodate many entire audio systems; Corian and granite outer shell and proprietary Stardust compound inside. Use "It does not run warm, does not limit current, can handle the conditioning duties of many entire systems without problem, and even includes its own power cord." Value "Cannot be considered inexpensive," but Bill has "done component upgrades costing as much or more that haven’t offered the same level of sonic improvement." At the Consumer Electronics Show a couple years ago, I ran into a good friend employed in the power-conditioner business. In the course of conversation, I inquired how his business was doing. With a protracted sigh, he stated something to the effect of "everybody is making power conditioners these days," a fact supported by the plethora of power-conditioning/-filtering/- regenerating devices currently available on the audio market. Without thinking too hard, I came up with the names of a dozen such devices in a matter of a few seconds. So what’s the subject of this review? If you guessed "power conditioner," you’d be partially right. The Shunyata Hydra would be categorized as a power conditioner, but it’s entirely different from what most of us have come to expect from products of this genre. Normal starting-out stuff The $1995 USD Hydra is the latest product from Shunyata Research, the folks that produce the much-heralded PowerSnakes line of after-market power cords. Housed in a strikingly attractive Corian box with polished granite end panels, this is not an industrial-looking, black-painted chassis. A wood insert in the front panel is laser-etched with the trademark King Cobra pictogram and adds additional elegance to the whole package. Measuring 10"W x 5.75"H x 14"D, the Hydra is quite compact and will easily fit on most audio-rack shelves. Along the back panel are three pairs of duplex outlets, an in-line fuse holder, and a NEMA 15-amp twistlock socket for the incoming power. Shunyata’s own Sidewinder power cord is included for use in conjunction with this connector, and just so there is no confusion, a standard IEC-terminated cord will not work with this fitting -- you must use the supplied Sidewinder or find an alternate cord fitted with the appropriate connector. The Sidewinder is an exceedingly good power cord in its own right, a SoundStage! Network Reviewers' Choice, so you don’t necessarily need to make up an excuse to play around with others. It’s quite nice to have a high-caliber cord included, instead of it being an additional-cost option that increases the base price. What’s it all about? If you find all this power-conditioning stuff confusing, don’t feel bad. I do too. So I asked Caelin Gabriel (the head PowerSnake) to provide an explanation -- in layman’s terms -- of what the Hydra actually does. According to Gabriel, traditional power conditioners and filters are designed from the premise that components need to be protected from RFI (radio- frequency interference) and EMI (electromagnetic interference) generated from sources external to the audio system. This has usually been attempted in one of two primary ways: impeding high-frequency bandwidth and/or redirecting electromagnetic energy. A third method, one that has been around for quite some time in the computer industry, has recently surfaced for audio applications: power regeneration. Gabriel contends that the primary culprit to power-line-induced sonic degradation does not stem from external RFI/EMI sources. His research indicates that the principle source of line fluctuation, EMI, and noise are generated by the audio/video components themselves. Gabriel believes that if this premise is true, power-conditioning/-filtering/-regenerating devices may actually degrade system performance by reflecting the EMI generated by the components back towards the source. The Hydra is based upon the same proprietary (and patent-pending) noise- reduction technology used in the PowerSnakes power cords. The Stardust material used inside the Hydra is actually a blend of several different chemical formulas. The various formulations operate in different frequency bands and are selected for the required application. Stardust starts from a chemical compound base that is fired in high-temperature ovens that cause it to crystallize into a hard, granular substance. Gabriel says that Stardust "literally absorbs high-frequency AC line noise" through an electromagnetic-coupling mechanism. The Hydra is constructed from an electromagnetically confined chamber that is filled with Stardust. It utilizes two electromagnetic-field-shaping bus arrays that "focus" high frequencies within the chamber. This reportedly increases the coupling, and thereby the effectiveness of the Stardust compound. The Hydra uses no conventional chokes or capacitors, and thus imposes no current limiting on components plugged into it. Layman enough for you? Usage The Hydra does not run hot (or even warm, for that matter), does not hum or vibrate, and due to the fact that it imposes no limit on current delivery, you can plug in most, if not all of your components (up to 1875 watts total demand). It has no ventilation requirements, which allows great flexibility in the decision of where to place it. I did find, however, that sonic gains were possible with some attention directed to what it sat on. Placing it directly on my static-prone carpet was discovered early on as the worst thing to do. After experimenting with a number of different isolation/tuning schemes, I settled with placing it on a Greater Ranges Neuance isolation shelf (borrowed briefly from underneath my turntable), with 1" Audio Point brass cones between the Neuance and the carpet covered-concrete floor. There are no absolutes in the isolation/tuning game, so it’s highly recommended to experiment and find what works best in your system. Regarding break-in, I’m as religious in my belief that it exists as are others who believe it to be strictly psychoacoustical. I have no fancy scientific thesis to present here, so all I’m going to say is that I gave the Hydra 100 hours of burn-in on a 400-watt light tree prior to assessing it sonically. It did not seem to change much, if any, during the review process, so either 100 hours is sufficient, or break-in truly is a figment of some audiofool imaginations. A final important note: the Hydra does not provide any AC-line protection, other than the 15-amp fuse. If lightning, damaging surge currents or miscellaneous (and catastrophic) power gremlins are a primary concern, then a means external to the Hydra will have to be considered. To be fair, many of the audio-oriented power-conditioning devices do not provide sufficient protection for such catastrophes anyway, so if you live in a severe- thunderstorm-prone area like mine, you’re better off unplugging stuff entirely when those warning messages start beeping on Channel 5. Up against the wall In order to draw a baseline for the sonic ramifications of the Hydra, and as a PS Audio P300 has been employed in my system for the past two years, I spent a couple weeks with the P300 removed and all components plugged straight back into the wall prior to introducing the Hydra. After sufficient acclimation to un-conditioned power, the Hydra hit the system. As the total wattage requirements of all my components fell well within the Hydra’s capabilities, I plugged everything into it, including the amplifiers.

The resulting sonic improvements cannot be described as subtle. The most striking change at the outset was a dramatic improvement in soundstage space and detail. I’m fortunate to have a dedicated room that is large enough to allow speaker placement well away from boundaries. This helps most any speaker I’ve used in this room produce a wide and very deep soundstage. The Hydra moved those boundaries a little further out, but what it did for the definition within that space was what caught my attention. Wide and deep is cool, but layering and specific localization, both front to back and side to side, is even cooler. On the title track from Linda Ronstadt’s Dedicated To The One I Love [Elektra 7559-61916-2], not only was Ronstadt’s voice moved further back in the stage, the accompanying vocals established their own separate location in relation to hers. You probably hear the phrase "3-D" often enough when expressing the qualities of a soundstage, and the Hydra could provide a dictionary definition of what that expression means. This enhanced soundstage creation and delineation were clearly evident on every recording I put through the system. Vinyl replay was a real treat. The next immediately apparent quality the Hydra brought out was in the area of micro- and macrodynamics. The Cary 805C monoblock amplifiers sounded like they’d received an injection of adrenaline. While they obviously didn’t have any more measurable power, they sure sounded like they did. Bass lines were stronger, with greater impact and heft. Increased volume levels came through with greater ease, without any sense of strain or compression that similar volume levels without the Hydra sometimes presented. In that mix of things dynamic, one of the most endearing qualities highlighted by the Hydra was the unraveling of microdynamic detail and contrast. A prime example is found on the title cut from John Lee Hooker’s The Healer [Mobile Fidelity UDCD 567]. Minus the Hydra, the percussive mix can sound a little confused. With the Hydra, each instrument's distinct volume shift was more easily discerned, and this lent a greater sense of rhythm and drive. Tonally, the Hydra has little (if any) effect. It does not impart additional warmth or brightness, nor does it strip any away if it already exists. A song that I’m very familiar with is "Red Shoe Tango," from the soundtrack to Red Shoe Diaries [Mercury 314-515584-2]. It’s a very short instrumental piece that’s nicely recorded and features some percussion and a nicely rendered saxophone. It captures the feel of the recording space to good effect. I detected no change to the tone and character of the sax, instead hearing only a better sense of the decay as each note ended. The drum kit at the end was more realistic in its presentation, with a better portrayal of the transient edges and detail. One of the qualities most people look for in a power conditioner is the ability to "clean up" the sound. Many of the better conditioners on the market do a pretty good job in this regard, removing or reducing noise artifacts commonly referred to as grit, hash and fuzz. The problem I’ve experienced with many products is that in the process of removing this noise, some of the music is removed along with it. And this is exactly what the Hydra doesn’t do. There is no smoothing, no reduction in treble energy or extension, no loss of bass impact, and no loss of dynamic swing. On cut five from The Phantom Of The Opera [Polygram 831 563-2], the vocals sans Hydra have a very pronounced edge and sibilance. With the Hydra in, much of that sibilance is reduced, yet the clarity of the voices scales new heights. Nothing is rolled off, clamped down, or covered up here. The organ delved more deeply into the nether regions of the bass, and the stage expanded nicely. What I got was more of the music, and less of the non-music. I had to bring in another listening chair for Mr. Clean, who came along for the ride and seems to have taken up permanent residence. Up against the PS Audio P300 Power Plant The PS Audio P300 has served well during the time I’ve owned it, and I found it quite revelatory when it first met up with my system. It made a significant improvement over straight-from-the-wall power, and seemed to impose much less of a signature to the overall sound than any conditioning unit that had preceded it. Due to the limits of its current capability, however, it was only possible to use it for front-end components. The amplifiers have been plugged straight into the wall, as well as several front-end review pieces that required more power than the P300 could handle. My P300 does not have the recently introduced MultiWave functionality, and I have not had the chance to listen to a Power Plant with that option installed. Hydra, take two Into a product category recently dominated by PS Audio's Power Plants and Richard Gray's Power Company comes the Shunyata Hydra. Yes, I know these are all very different products in terms of the technology they use, but they all claim to do the same thing: help your audio gear sound better by improving the power fed to it. I've used the P300 Power Plant and Richard Gray's Power Company at length, so I have some context with which to evaluate the Hydra. Functionally, the Hydra is very flexible, able to accommodate my entire audio system, mono amps and all. And to my ears, its sonic acuity falls into the realm of clarity. Things didn't sound veiled, hashy or murky before I added the Hydra, but the sound afterwards was noticeably more clear -- like looking through a newly cleaned window, or perhaps no window at all. Images had more specificity in the soundstage, which opened up in all directions. The air around performers was more tangible, and the performers themselves sounded more present. I could detect no tonal coloring -- the Hydra doesn't editorialize in any way -- but tonal shading did improve, showing more gradations. Even the bass seemed a little more lively, the Hydra allowing the lowest notes to emerge with greater drive and pace. The PowerSnakes line of power cords is uniformly terrific, but the Hydra is the Shunyata product to buy if you can afford it. The Shunyata Hydra has become an important part of my audio system, and it's a reviewer's dream component: no sins of commission or omission to discern and describe. It just makes an audio system sound better -- clearly better -- and this makes it the most effective power-line product I've used. ...Marc Mickelson marc@soundstage.com In order to level the playing field as much as possible, the comparisons noted below were compiled from my listening notes with just the front-end components plugged into either unit. This might be a bit unfair to the Hydra, as it could handle my amplifiers. So shoot me. It’s only fair to note, however, that the sonic improvements offered by the Hydra powering all components is even more significant than when it's powering the front-end components only. In direct comparison, the P300 lent an overall air of politeness to the music, while the Hydra lent an overall air of excitement. In my system, the P300 does a very capable job of attenuating and/or eliminating sonic nastiness and garbage, stripping the aforementioned grit and hash out of the music. But it softens transient attack and snap in the process. Subtle shifts in microdynamic information are masked somewhat, which is something that isn’t entirely evident until the P300 is taken out of the system. The Hydra instills a pronouncement of these shifts, which perhaps is what makes the difference so large when doing a direct comparison. If you stumble into a conversation with avid vinyl spinners, you’ll likely hear the term PRaT (Pace, Rhythm, and Timing) bandied about. If you’re not sure exactly what that means, pop a Hydra into your system. Then you’ll know. This comparison is not meant as some backhanded condemnation of the P300, as it does a large portion of its job exceedingly well. But it also does some things in the process that are not entirely welcome -- and these may go unnoticed due to the very things that it does so well. The Hydra seems to pull off the remarkable feat of cleaning up without cleaning out. One issue to consider is that the air of politeness offered by the P300 may not necessarily be a bad thing for a source (or system) that has some unwanted brightness, or suffers from a relentless or edgy treble presentation. The Hydra does not attenuate anything, and there are some systems that may actually be easier to listen to with a bit of smoothing in that area. Conclusion Reviewers are normally chastised for writing reviews that come across as too much of a rave. As far as the Hydra goes, I guess that I’ll just have to be chastised. In my system, the Hydra simply improves the sound in all respects. It improves it in some areas substantially, and brings the improvements to the table without imposing its own sonic signature or adding a laundry list of contrasting negatives. It does not run warm, does not limit current, can handle the conditioning duties of many entire systems without problem, and even includes its own power cord. At a retail price of $2000, it cannot be considered inexpensive, but I’ve done component upgrades costing as much or more that haven’t offered the same level of sonic improvement. After I completed my listening time with the Hydra, I sent the unit to Marc Mickelson for further evaluation and comment. I found that I had no real interest in listening to my system once the Hydra was gone -- things were just boring and uninvolving. The true test of any component is whether it brings you closer to the music and causes you to spend more time listening. The Hydra passes that test with flying colors. ...Bill Cowen bill@soundstage.com Shunyata Research Hydra Power-Distribution Center Price: $1995 USD. Warranty: Ten years parts and labor. Shunyata Research, Inc. P.O. Box 27740 Las Vegas, NV 89126 Phone: (877) 727-7023 Fax: (425) 671-0648 E-mail: info@powersnakes.com Website: http://www.powersnakes.com/ ------------------------------------------------------------------------------- - Shunyata Research responds: Shunyata Research would like to thank Bill and Marc for their thorough review of the Hydra and for deeming it worthy of the Reviewers' Choice award. We are proud of what we have accomplished with the Hydra and believe that Bill and Marc have accurately conveyed the essence of what a Hydra brings to the performance of a high-quality music system. We are especially pleased that although Marc and Bill have very different systems, they came away with similar impressions of the Hydra's sonic abilities. Because Hydra does not use reactive components such as MOVs, capacitors, transformers or conventional coils, it will be compatible across a broad range of systems. We would like to take a moment to offer our point of view on surge suppression and why the Hydra does not include it as part of its construction. Surge suppression is usually accomplished through the use of MOVs (metal oxide varistors). In the event of large voltage surges, the MOV is designed to turn on and start to conduct current in an attempt to prevent the surge from reaching the equipment. MOVs are quite inexpensive and we could have easily included them in the Hydra, but we chose not to for two reasons. First: MOVs function by diverting or shorting current to a ground path. This ground path is the neutral or ground conductor in your home wiring. The wiring from your home's electrical panel to the outlet can present a significant impedance to transients and voltage surges. This increased impedance will reduce the effectiveness of the MOV in its attempt to divert current to ground. Second: MOVs are considered "sacrificial" electrical components. This means that they have a limited life span that is dependent upon the number and severity of surges they experience. In other words, MOVs burn-out just like light bulbs and become ineffective. If MOVs are installed in a power-distribution device, there should also be an LED to indicate that they are functioning properly. Also, there is the problem of replacing the MOVs. Does the customer perform the modification or will the device be returned to the manufacturer? For those who live in an area that has frequent electrical storms or severe power-surge problems, a better solution would be to install surge suppression at the electrical panel. Many of the new homes built today include this protection because they are wired for computerized equipment. This solution protects the entire home and the effectiveness of the MOV is assured because it is installed at an optimal location with a short path to ground. For example: G.E. has a surge suppressor that is designed as a circuit-breaker module so that it simply plugs into an existing electrical panel. It includes indicator LEDs so that the user can be assured that the unit is operating properly. If it burns out, you would simply replace it. This unit costs less than $100 for full-home protection. Contact your electrician if you would like to install surge suppression for your home. Thanks again to SoundStage!'s Bill Cowen and Marc Mickelson for the comprehensive review of the Hydra power-distribution center. Caelin Gabriel President and Founder Shunyata Research Inc. |

吗? 虽然新旧两款产品都叫做Hydra,但外表看上去已是南辕北辙,而内部的结构更是 相 差十万八千里,新款Hydra比旧款强了不知多少倍。旧款Hydra排插最值钱之处是内部空 间 灌满了用来吸收电磁干扰噪音的[星尘]物质,只此而已,别无其他东西。而新款的Hydra- 8 当然也少不了灌满『星尘』,但就算把Hydra-8里面的星尘完全倒掉,剩下来的结构也完 全 可以当作一个Hi End极品排插。 Shunyata Research不是现在才推出排插,早在三年多前笔者就试过一款 ShunyataResearch出品,木壳面板的Hydra排插,当时测试时的音效已令笔者折服不已, 最 终没有留为己用的原因只是没钱而已,想不到事隔三年有多又轮到在下进行测试,这一 次 试的排插仍然叫做Hydra,不同的是后面多了一个8字,全名叫做Hydra-8,之所以叫做8 明 显是因为有8个输出插座的缘故。 虽然新旧两款产品都叫做Hydra,但外表看上去已是南辕北辙,而内部的结构更是 相 差十万八千里,新款Hydra比旧款强了不知多少倍。旧款Hydra排插最值钱之处是内部空 间 灌满了用来吸收电磁干扰噪音的[星尘]物质,只此而已,别无其他东西。而新款的Hydra- 8 当然也少不了灌满『星尘』,但就算把Hydra-8里面的星尘完全倒掉,剩下来的结构也完 全 可以当作一个Hi End极品排插。 Shunyata Research公司在Hydra-8上—次过地采取了多项觊声措施,这些措施几 乎 包括了一切电工技术中用来净化电源的[最]理想方法, Hydra-8可以说是目前市面上一款集成了最多先进技术的电源排插,笔者认为不介绍一下 其 内容的话对不起厂方的诚意,当然如果看官没兴趣的话可以略过以下的技术简介,直接 跳 至声音测试部份。 三叉戟 Shunyata Research把靓声八招中的头三招合并在一起,叫做TRIDENT Power Protection System,意思是三又戟电源保护系统。这个系统不单止保护电源安全,同时 亦 保护了声音质素,三叉戟中的第一叉叫做VENOM滤波器,实际上是一个四元件电容阵列 线 路,这个线路的主要目的是消除过电压脉冲,作用范围从数伏特至上千伏特,虽然电容 器 是消除过电压的一种常用元件,但Hydra-8的电容器却与别不同,原因是经过相当时间的 筛 选,厂方选择了金属/聚酯电容器作VENOM滤波器的主要元件,这种电容器在遭到轻微破 坏 时具有特殊的[自愈合]特性,因此可以某种程度地耐受高出设计值的电压,除此之外金 属 /聚酯电容在吸收过电压时较不易出现铃震现象。 三叉戟的第二叉是NextGen TMOV,MOV是金属氧化物压敏电阻的简称,其主体原 料 是氧化锌粉末,经常规陶瓷工艺烧结而成。MOV的用途极广,全部都是应用在各种情形下 的 过电压抑制,但Hydra-8的TMOV到底是甚么玩意厂方没有透露。笔者个人估计有可能是 SrTiO3复合功能陶瓷压敏电阻,这种压敏电阻在低压电路中对高电平,低频率的干扰具 有 出色的抑制能力,厂力的资料也明确地指出,TMOV主要是配合VENOM滤波器对大约在340V 至 6000V范围内的过电压进行抑制。换言之两者之间有一个340V-1000V的工作重叠区,确保 对 高电压脉冲有杀错无放过。 三叉戟最后一叉是Carling Electromagnetic Breaker,也就是Hydra-8机背那 个 开关掣,这可不是一个普通的开关掣,而是一个像大部份家庭厨房电掣箱里面的[电掣] 一 样的保护[跳掣],学名叫做断路器,作用和保险丝一样,当电路发生过电流意外时能迅 速 地切断电源。普通断路器对音响来说有两大缺点,第一是接触点面积太小,第二是把跳 掣 内部的导电体充作保护元件,例如当出现过载(Overload)时导电体因发热而弯曲,从而 将 接触点顶开。CarlingElectromagnetic Breaker则摒除了这两项缺点,首先是接触点面 积 扩大到可以流过比设计值大的电流,其次是采用了独立於主电路之外的保护电路,无论 在 任何情形下都不影响音质。 包罗万有 除了保护系统外,Hydra-8还有多项靓声措拖,其中一项措施竟然和笔者在数月 前 摩自己的土炮排插的方法一模一样,当时在下摩完排插後自以为得计,洋洋得意地以为 自 己是第一个想到此办法的人,怎知看了Hydra-8的资料后才知道自己的想法是大错特错。 这 个靓声措施就 是一个巨型的汇流排,笔者所选用的是1寸厚铜巴,但Hydra-8用的却是1.5寸厚铜巴, 长 达5寸,一共三条,总重超过5磅!如此规模的铜巴不要说是20A,就算是1000A也不成问 题, 这还不算,三条铜巴竟然是经过了超低温冷冻处理的,将一切影响电流通过的因素都降 至 最低。 冷冻处理不单止用在铜巴上,Hydra-8装了8个Hubbell输出插座,全部都经过冷冻处理以 提 高导电能力,因此对整个Hydra-8来讲,电流的流通都可以用自由行来形容。 在导电和保护方面,Hydra-8是做足101分,但还是不够,作为一个音响排插, 最 重要的任务是降低噪音。为此Hydra-8沿用了Shunyata Research公司的独门绝活——星 尘,星尘的商品型号叫FeSi-1002,从型号中可以看出,星尘属于硅(矽)铁化台物,是一 种 人工合成的陶瓷类物质,由于星尘中的铁和硅是以化合物分子形式结合,所以星尘是不 含 金属的,但星尘却神奇地具有铁氧体/纯铁一般的吸收电磁幅射噪音的能力。有许多人 不 知的是,铁氧体制成的涂料是隐形战机其中一种用来吸收雷达电波的涂料,而星尘具有 同 等能力,可想而知其效力如何,星尘还有一样优点,在吸收噪音时不会对电流产生动态 压 缩效应,在音响来说这绝对是一个优点,不过对隐形战机来说这可能是一个缺点。 声音表现 对于Hydra-8这样一个集诸般武艺于一身,毫无电流限制现象的排插,接驳时当 然 不用客气,甚么CD机,前后级等等器材我一古脑全插在Hydra-8的屁股上。Hydra-8的电 源 插座是IEC320的20A扁脚式,为此选用了一条同厂的PYTHON ALPHA电源线,试音菜单如 下: 前级:McIntosh C46 后级:McIntosh MC402 喇叭:Thiel CS 2.4 接线:Zu Warmouth/Gede→-Varial→Ibis 即使是初开声,Hydra-8也具有令人耳目一新的表现,声音非常的开扬,但总觉 得 有点欲语还休,不太自然的感觉,煲了大约一个星期后,整体表现开始稳定下来,声音 从 容不迫,是时候考验其功力了。 很少电源系统能做到Hydra-8那种豁然开朗的声音感觉。在声音未出时Hydra-8 是 完全宁静的,给人一种老僧人定般的寂静感,但声音一出之时,尤其是动感较强的录 音, Hydra-8就像一部油门踩到底的超级跑车,飞弹而出,无论高中低频、速度和控制力都有 明 显地加强和改善。 Hydra-8具有超强的空气感,笔者使用中的SonySCD-1本已是空气感出色的产 品, 但Hydra-8仍然能将其空气感多榨出一成以上,听Belafonte at Carnegie HallSACD中 的 “MATILDA”,本来此张SACD的制作水准很是一般,但有了Hydra-8的扶持下音效竟可以 跳 升一班,细碎的杂音和现场各种反射音纤毫毕现,将整个表演舞台音源:Sony SCD-1幻 化 出来,舞台的大小和高度清晰可辨,Belafonte和乐队在舞台上的位置以及走动的情况被 交 代得一清二楚,歌曲的动态明显得到增强,Belafonte和听众及乐队之间的对答,全体一 起 Jam歌的情形有若身历其境,立体感和像真度非常出色。 试空气感少不了EVA CASSIDY Live at Blues Alley中的Bridge Over Troubled Water,声音未出之前我本以为会在歌曲的前奏段听到一大堆刮耳的磁带噪音,但结果却 出 乎我的意料,不错噪音的量和幅度是有轻微的增加,但听起来却一点也不觉得刺耳,相 反 地歌曲的真实感和现场感却得到增强。EVA的歌声磁性不减,而位置感和轮廓却被刻划得 格 外鲜明,谐波余韵和细节的增加使歌曲显得更加动听。因试音的关系,我本来对这首听 了 N 次之多的歌有点生厌,但Hydra-8却令我在不知不觉间将整首歌听完,完全没有半点讨厌 的 感觉。 Hydra-8的低频骤听之下除了控制力较为出色外,在力度和下潜力方面似乎没 有 甚么特别,听去年香港高级视听展[原音精选]CD的第一首A Groovy Kind Of Love便是 如 此,开头的鼓声除了收放更加自如外,下潜力和冲击力似乎没有甚么明显变化,但到了 随 后的Rimsky Korsakov:Scheherazade Op35,情况就不大一样了,低音大鼓一出有如排 山 倒海,超低频像是一堵墙一般地推过来,整个乐队不散不乱,声音快放快收,层次分 明, 每件乐器的位置和声音轮廓都清晰鲜明,即使在高潮合奏之时,解析力也没有降低,声 音 之中的细节变化听得异常清楚,丰盈的谐波和空气感包围着整个乐团,乐曲变得更加有 生 命感,更加有活力。两首乐曲的音效分别其实很简单,第一首的A Groovy Kind Of Love 的 配器较为简单,单一件乐器的重现不容易考起电源器材,但第二首情形就不一样了,低 频 混入大量的中高频讯号,电源系统处理不了大量猝发性讯号的话极易出现脚软或含混不 清 的情况,Hydra-8显然轻松地通过了考验。 Hydra-8的售价为19,500大元(去年起又涨了25%),不论声音表现,只计内部 采 用的科技措施已值回票价,更何况Hydra-8那超级传真的声音质素,绝对值得推荐。 |
