銀牛係好,但以我部 K2m 個功率,冇返七、八千成本,冇可能係純銀牛,坊間有鍍銀牛,做機例如 CD、DAC 之類 ok,做 AMP 或好似 K2m 咁做主供電,會令 d 聲太快太急。

Hi Wilmer,

I am interested in it too. Might I ask some questions about it:

1. The most general que ...
sokwan 發表於 2012-3-2 14:28 http://www.post76.com/discuss/images/common/back.gif


1. The most general question is what kinds of benefits for sound (or even vision in TV's case)?
ANS: Other ching did posted result, you can read again for reference, I of course be a seller will say everything are wonderful{:1_263:}

2. Can it be turned on all the time, like refrigerators? Is it energy-consuming in this case? Will the heat be high?
ANS: No power consum assd long as you hifi system nothing tune on, can keep power on all the time

From the figure in #38, it indicates that power amps should be used in "bypass" sockets while integrated amp (<100W) use sockets with Sine reform.
ANS: Basically yes

3. Might I know why power amps need not to have sine reform, but pre-amp?
ANS: You mean integrated amp, right? Actually not really only for int. amp, just an easy indication of each outlet maximum loading capacity, you can test which outlet's sound character best match with your int amp/preamp.

4. For those devices using "bypass" sockets, can they get any benefits from using your power plant?
There is ground loop braker for whole circuit, plus parallel filter on the return path, therefore even the bypass outlet, also can get rid of any noise feedback.

5, Why CDP and DAC needs only isolation but no sine reform?
ANS: Same as Q3, you can test by your own, but since CDP and DAC are half digital half analog, isolation will help aviod any HF noise feedback to other devices.

I am just using a ordinary power bar with Furutech GTX-D (R) in it. From my little experience, when I try to connect pc from TV box (Magic TV) to the power bar with my other HiFi gears, there is some kind of distortion in sound.

6. Is this the reason why (and the function of) the (sine reform+isolation) sockets are for TV, etc purpose?
ANS: Yes, and also any pure high fequency device other then need as clean as possible power, also as Q5, need to aviod noise feedback to other device, not just through the return path or ground, but through whole circuit, therefore other then sine reform, isolation also needed.

回復 144# Wilmer威馬


Wilmer, thanks a lot for your detailed and professional explanations.I am so sorry that I am still not so clear about some points. Will you kindly offer some more elaboration on them?

1. Since the bypass outlets are for poweramps (or devices that demand higher loading capacity), why sine reform is not important in this part of Hi-Fi system? Is it the case that sine reform for power amps is not as important as for other gears, like preamp, DAC, CDP?

2. How will sine reform change sound character? (or more basic question: will it change sound character?) Since the CDP and DAC outlets are for isolation only (no sine reform, right?),is this design for the consideration of not changing the sound character in the source part?

3. A related question is why then there is sine reform in the preamp part? Is this design purposefully for achieving the best results or issues about loading capacity, etc?

Suppose that I buy your power plant. Do you think I will get an extra benfits from connecting it with my present power bar (pure-no filter or any other things) power bar using GTX-D (R) outlets (clean power from your plant and best contact from GTX)? Or the components inside your plant are chosen for optimum performance so the addition of my power plant will do more harm than good?

About the bypass, I did told there are also treatment about grouding and return path, nothing is not important.

About sound, it is better you line up and wait for pay deposit hoome trial, better then thousands words from me.

And all other about "technically why", since you have no technology background, therefore there is no why, all I can say is this is my design philosophy, as long as you trust, no why, if not trust, even further million words still make nonn-sense for you.
