I recently bought a pair of Snell XA-90ps and I am trying to find the 'perfect' amp for them. Can you guys help me with some suggestions or point me in the right direction? I am currently considering a Bryston 4B SST and a Krell KAV 2250. I know I should listen to different amp but due to my proximity to a decent retailer, I am limited to what I can hear. Thus, I was hoping you could help me narrow my search to just a few amps, so I do not have to drive all over the state to different dealers.
