Hi 702, unlike me you seem to have a good knowledge of electronics and why things should or should not work. I believe that most PC,IC, speaker cable, ETC have a sound, coloration or whatever you want to call it. Maybe thats part of our problem. When I put something new in my system, I expect a change in sound. You are coming from a different point of view. I guess you don't expect a change in sound with PCs. Maybe we both have preconceived ideas. As far as double blind testing, I have tried and failed but that does not mean PCs are not a benefit. It just means I failed. I could give reasons why double blind testing doesn't work for me but it would sound like I am making excuses.
I don't think you are a pseudo intellect, I think our background in audio sometimes gets in our way. Even though I failed blind testing, at least I gave it a try. Have you or will you give a PC a try? I have one you can borrow for a week or two. I took the PC challenge and failed but it doesn't change the fact that PCs can be a valuable upgrade. I challenge you to try my PC. With this challenge there is no failure. You hear a difference or you don't.
Hang in there 702, I like the way you stand up for yourself. I agree with Jhunter, I think you are getting less respect than deserved.
