Mapman, thanks. I know it was a while ago, but how would you assess trebles? Was it an "airy" presentation? My Rowland is a little bit on the darkish side according to one editorial review. AHB2 might be good step-up for me from entry level class D, not to mention that is also very efficient with idle power of only 20W total and 0.5W at standby. I also like the fact that it utilizes quiet SMPS since it is efficient, plus line/load regulated and not sensitive to DC on mains (no transformer buzzing etc).
