4.7 uf input cap

Shaun Perez 2 · 19th November 2004, 06:47 AM

Has anyone tried paralleling 5 1uf black gate type n's instead of just using one 4.7 value unit. I am tempted to try it, should lower inductance and the cost wouldn't be too much to try. Any experimenters out there??????????

I used to parallel caps like that (although of different values) but once read that it can smear the sound.

I don't know that my experiences supported that theory but these days, often for reasons of space, I prefer to go with a single 4.7 uF polypropylene cap.

In my experience 5 x 1u will never sound as good as a single cap, especially for BG and for coupling.

To Peter : I don't belive, but what is your explanation ?

The slight variation in caps will result in multiple discharge times smearing the signal over a very small timespan.

I don't have explanation, I just share my observation.

anyone tried using bg hi-q as a bypass cap with bg nx as output cap or super e-caps using hi-q as output cap? thanks =)

I tried them, but to me, N type sounds the best, both for coupling and bypas. It's more neutral, while NX and Hi-Q are softer and kinda tube like sounding.

I tried Super-E for coupling, but preferred a single cap with Non Polar print towards incoming signal (as orientation is important here)

This makes me thinking: did you ever try listening to different parts and compare them subjectively?

To everybody: I just installed BG N type 4.7u caps at the output of my new DAC and they sound so good. It's really hard to find a better sounding film cap, and frankly, I wouldn't even bother. It's no wonder that Michael Percy used to write on his site that in some circles, BGs are regarded better to ANY film cap in coupling applications
