Question: I have been on a quest for audio nirvana for years now. I keep going back and forth between tonality and neutrality, if you know what I mean. Some components seem to add something that is pleasant but is this what I want? Other components seem to be more neutral and that sounds best to me in some cases but in others it isn't. My latest focus is on caps. Paper in oil caps have that warm holographic sound that you can definitely hear. Poly caps sounds just like a straight wire - you can't hear them at all. Isn't that what we want? On the other hand, oil caps sound mighty good in the right places. Right now I'm thinking poly caps in the crossover and oil caps in the amp. That spreads it around and sounds right to me. What have you guys used that sounded great?
I am long past the age when I could hear such fine distinctions as you are making, but let me ask a question and make a suggestion. Is there any other way you have found to produce "that warm holographic sound"? If so, then I would go the Poly cap route because it is neutral and your putting it where you hear it all the time. For those times when you want the special sound, switch it into the line up so that you can also switch it out when you don't want it. Like a "tone control". Bob Carver had a circut once that was claimed to produce such an effect. I never heard it, but some liked it, some didn't. -Dick
