Which Class D Amplifier? PS Audio, Ghent, Nord, Merrill or other???

One caveat: ordered Rothwell -10db Attenuator because preamp+power amp gain is too high, I can’t go beyond 9 o’clock on volume pot, so attenuator will help in pushing noise floor down and give system room to breathe.

"One caveat: ordered Rothwell -10db Attenuator"  
You "push" both signal and noise down of the source and pre, and "maybe" create an impedance mismatch so your no better off.

If you really want to lower the noise floor, get a preamp with less or no gain, then you’ll use most of the signal available from source, pre and power without boosting the noise floor.

"Hello @aolmrd1241 and @KLH007, I will post some observations about the darling Rowland M535 tomorrow... It won’t be the complete review, but I’ll try address some differences between M535 in stereo mode, and a bridged pair..Saluti, Guido"

Hello Guido... Is the Rowland M535 review by any chance close to nearing completion yet?

Thanks...Mark

Mark, Looking forward to your comments on the JRDG 535, as stereo in comparison to other $5 to 10K amps, and vs a pair as monoblocks.

I have had and listened to many amps and have been in this stupid game many years. I have settled on class d because it sounds so Damn good for the money but also for the convenience. Yes a krell fpb300 sounds better than my sti500 but not that much better, and costs way more up front, way more to run and will probably need repair sooner. The only real area that is better is some image depth and 3d, but its not much. I don't think there is better value than good class d. Plus I have never even listen to good class d, driven by a really good tube amp. That may be the real end game!
Have fun playing the game! I do.

Have enjoyed this thread. I’m narrowing my search between Bel Canto REF600m’s, and PSAudio M700’s. 

Currently own Bel Canto REF500s, driving Vienna Acoustics Beethoven Baby Grand SEs.

If anyone has experience with both the 600M and the M700, I would appreciate your impressions. Thanks.
