I didn't get to spend very much time at all this year at RMAF. From my brief stay there, I really only have two comments. First, I agree that the Focal room wasn't as impressive as last year. In fact, I'm not sure if it was even close; I'm going to chalk it up to the lack of Boulder products this year.
Second, I was once again pretty impressed by the Nordost room. While I noticed a fair difference in some of their product demonstrations, they didn't really make me want to pay for Odin or Valhalla cables. What they did make me want were the speakers. Last year I was very impressed by the size and clarity of the sound coming from the $36,000 Raidho Ayra C3.0 speakers, and this year I was still pretty impressed by the $14,000 Raidho Ayra C1.0 speakers. (I'd love to try them at home, but they are virtually never on the used market)
Also, maybe it's just me, but it seemed like a number of rooms had somewhat lower end (as far as super high end stuff goes) equipment than last year. Coincidence, or because of the economy?
