Glad we could amuse you Stefan, if you took in the entire thread you should have noticed the OP has a limited budget, so BAT is as out of range as the Krell or Bryston I mentioned in an earlier post. The Adcom and Emo are capable of producing decent amounts of current, may not be optimum but far better than a receiver. As I mentioned I personally haven't had hands on the XPA-2 but on paper and with the number of output devices it looks like it shouldn't do so bad at driving the 9's.

IMO if some one found the Poly Dome harsh there must have been a problem. I always found them to be very smooth. They were made by Vifa.

Bfalls, the 9's may be rated at 4 to 6 ohms but the impedance isn't stable and can dip dangerously low for all but quality amps capable of high current.
