I have alot of experience with this. Caps make a huge difference in sound. I put Jensen copper in foil caps in my 805C, 300SE and now my SLM200's The caps actually take a long time to break in. But when they do, you will hear it. About 100 hours is right. This is not hype, it is very easy to hear in a very resolving system. I do not like the sound of the kimber caps. For preamps, I would not recommend the Jensens. I put them in my SLP98 preamp and it just didnt do it for me. In there, I spent the bucks and put in REL Teflons. They made a great preamp into one of the best i have heard.
I have experimented with caps for over 15 years now, it is not hype. dont ask me to explain why, i cant. But it is real to me and others that I have helped.
