Bypassing filter caps with Smaller caps - Page 3

Coconuts 500 · 8th April 2012, 07:54 AM

I installed a socket onto the filter caps in an amplifier, so that I could install a bypass cap there - in real time. I plugged it in out - during listening. Did a very extensive test.

I could not hear any difference at all. Absolutely nothing.

Before that, I used to install them blindly, and then just assume it made a difference. I really thought I could hear it. Obviously I was deluding myself.

Good to hear.
What type of amp was it applied to ? I have my doubts that it would make enough of a difference in a gNFB amp where the sort of changes would be smoothed out. My amps use local feedback.

glad to hear that.....this is a big amp that i did several months back.....

this is the power supply filter bank composed of 12 x 2200ufd/450volt computer grade caps, no bypass caps were used....

McIntosh used bypass caps back in the day and they were the biggest bunch of hard-core hard numbers guys around. They also didn't have modern caps with modern high frequency capability..

As for listening tests, if someone tells me they improve things, I'd believe him. OTOH, if someone says it hurts the sound somehow - I'd have a hard time buying that.

These are 58 cent parts.

Ha ha, I'd believe him too IF he can pick it out in an ABX test

I personally wouldn't take anyones word for it - I would try it myself and form my own opinion.

I wouldn't take MY OWN word for it unless I could pass an ABX test

Get my drift?

If I have to strain myself to hear a difference then it's not worth my time, since that's not how I listen to music. If it's not audibly significant, I don't sweat it. I chase pleasure not perfection.

I am not a golden ear nor do I want to so I will let someone else to enjoy the AB test while I go spin another record.

when other guys listen to my amps, i keep quiet and let them have their say, i value their comments as a means to improve my amps.........or to confirm what i already knew.....

most of the time, their issues were about cosmetics.....
