Definitive Audio in Bellevue, Washington has a couple of well set up rooms. But I'm looking forward next weekend to going for the first time to Shibuya HiFi - a Japanese style listening lounge in Seattle. They have a few rooms, and I believe the room I'll be listening to John Coltrane's "A Love Supreme" in is the one with a vintage (1970's) pair of Klipschorns driven by either Luxman or Marantz electronics.
