In Reply to: Sonic Signature of Caps??? posted by The Mad Hatter on April 11, 2010 at 08:52:12:
Caps have a major impact on amplifier sonics, probably second only to our choice of tubes... and at this time there is no perfect capacitor, so... everything is a trade-off. Much has been written about the different effects of caps in their two major applications; power supply smoothing and decoupling signal stages. The Chris van Haus write-up is very amateurish and subjective... but there have been many others... and the truly objective studies have always concluded the same way... (see above).
The teflon caps are always very identifiable and Peter Qvortrup has spoken out about them so very strongly in his writings, that I feel I should uphold his sentiments in the Audio Note Kits. I have not heard one piece of Audio Note gear (in its price/performance bracket) that I felt would be improved by the addition of teflon caps of any make.
I have used small values (like .01uf) as bypass caps in my own designs when I wanted a little high end extension or clarity but this has not been necessary in any of my AN's.
One thing is for sure... the Black Gates are the best for smoothing, and AN Silvers the best for decoupling. No-one seems to argue that! Now... we are faced with the shortage of BG's and the high prices of both the BG's and the AN Silvers, so how do we compromise?
My quest has been (and still is) to maintain the Audio Note sonic signature in the Kits, while using the components that give the best ROI. My point being that if you have plenty of disposable cash, go and buy the AN Finished Products... you won't be sorry! For the rest of us, trying to reach Sonic Nirvana by modifying the AN Kits is a worthwhile cause... keeping many away from fast liquor and faster women... or driving us to them!
So, if you want to maintain that Audio Note sound then use the components that will get you there. If not... do whatever you please and simply put your own logo on the faceplate.
I feel that I have been reasonably successful in my endeavour, because not one Forum member who has implemented my enhancements has taken them out.... well, in full disclosure, two members did, temporarily and for different reasons. Now if I can just convince everybody that I can lead them to the promised... ;-)
Until next time... enjoy the music...
