I'm about to order T+A PA 2000 R amplifier for my 9 K, which is 100/200/300W at 8/4/2 ohm respectively. And real world (lab) reports say it can deliver up to 400. And it's pure analogue power, not some class D stuff. Will certainly post my feedback after. I also believe this brand deserves it's own "manufacturer forum" here. Had a pleasure to listen my speakers with 2500 model (more power, but the only difference is doubled power supply), but at that time the speakers were right out of the boxes and even a little bit frozen
. Even in these circumstances it seemed to be a perfect match.
Meanwhile I'm rebuilding my audio room with soundproofing and acoustics treatment. And I think room correction will have more impact for bass reproduction.
