Music Lovers is a great place to go. I've never been to the Berkeley location, but the SF one is great. From what I hear, the Berkeley store is moving to a new location so it might not be the best place to go audition stuff. They're the local dealers for Wilson, Revel, Sonus Faber, VTL, SME, amongst other high end brands. Their set-ups at the SF store for Wilsons and the new Revel Salons are really quite impressive. Audio Vision isn't a place I particularly like going to. They expect you to buy something in there and can get testy if they think you're taking too much time. Their store is also overflowing with gear and it can be a pain to audition stuff there. If you're into analog, it would behoove you to make a trip down to The Analog Room in San Jose. It's a fun, club house-like atmosphere and they have excellent set-ups with very nice stuff to listen to. They're very big into AirTight electronics there, which is nice because there aren't many dealers around.
