Wyatt and Purer, you must like this baby.

(作者:Roy 时间:2002-03-20 19:02:15)- personally i don't think this is a value for money product 'cuz it is so very expensive (Over 10 times of the DAC1.1) and yet it use exactly the same DAC and Receiver as the DAC1.1x.
But this is a good example of how good a simply circuit can be, if not considering cost.- personally i don't think this is a value for money product 'cuz it is so very expensive (Over 10 times of the DAC1.1) and yet it use exactly the same DAC and Receiver as the DAC1.1x.

(作者:Roy 时间:2002-03-21 11:44:00)- 昨晚与Wyatt兄研究了一通,此DD图中间的两只硕大的类似铝壳电容的物体原来不是电容,乃是Audionote之独门秘技I/V转换牛!DAC芯片输出之电流直接经此牛变换成灯胆的推动电压,灯胆输出再经过两只硕大的(对DAC输出级而言)30:1输出doube C-Core牛直接作平衡推动,信号不经电容(两黑色电解为灯蛋退耦电容),并将输出阻抗降到1/30(只数十ohm).
此I/V牛乃Audionote采用之18bit,1X取样下仍然可以大副滤除数码声的关键。
唯此10只牛(2xpower+4xchoke+2xI/V+2xoutput)成本高昂,(光买牛就超过10万,纯银绕制,0.025mm厚之SR48高纯镍合金铁芯)
Simply is the Best之又一印证。- 昨晚与Wyatt兄研究了一通,此DD图中间的两只硕大的类似铝壳电容的物体原来不是电容,乃是Audionote之独门秘技I/V转换牛!DAC芯片输出之电流直接经此牛变换成灯胆的推动电压,灯胆输出再经过两只硕大的(对DAC输出级而言)30:1输出doube C-Core牛直接作平衡推动,信号不经电容(两黑色电解为灯蛋退耦电容),并将输出阻抗降到1/30(只数十ohm).
