What's your High End best buy/unknown components?

I can't say that Quickies are unknown since they're known for their excellent value and built quality.
Three folks already spoken for them and I speak fourth on Quickies so logically they're well known.

My best buy has been my Fi preamplifier by Don Garber. I also second the quicksilver recommendation and have had Mike Sanders 60 watters, silver mono 90's, and now his M135's. Great stuff.

Not too many people know, but Michell ISO phono preamp that retails used $200 can easily humiliate Phonomena with BPS.

Just as a follow-up to what Kenl said, Ric Cummins provides fabulous customer service. I was an original purchaser of Argent Room Lenses. They arrived with a rather amateurish finish. Several years later, the Room Lenses were a big hit, and the production was much more evolved. I asked Ric if he would refinish mine, and he did so without a hitch, and even replaced a couple and paid for return shipping. Great guy! Exactly the kind of person you would like to see achieve success in this business.

HP 110 amps from star sound. Check out audiopoints.com. The site doesn't do credit to these remarkable amps. I have a big system with a dedicated acoustic treated room and had listened to great stuff from Levinson, Krell, Spectral, Pass, and many more. I was ready to buy these name brands when a friend convinced me to demo the HPs. When properly broken in these cool running seemingly low powered amps are as dynamic as anything I have heard. Very rememiscent of the tube amps. The more I play the more they have openned up and I am already way beyond being satisfied. I don't know how these guys do it and I really would like for someone else in the business to review these although I know what I am hearing and was skeptical at best at the outset. I have Revel Studios and these more power them up. Unless you need a big power rated amp to compensate for other lesser equipment than the HPs are more than enough for almost any application. My buddy is seamlessly running some big Dunleavys with these. Check audiopoints.com.
