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

The D doesn't stand for digital. Can we please stop with the digital amp thing already? That is incorrect. There is no such thing as a digital amplifier.

Class D amps are analog!

If it's in your budget, you might want to look at Theta Digital Prometheus Amps (sometimes used pairs come up on Audiogon).  I had them in my system for 6 years and they performed perfectly.  Class A ratings from the hi-fi mags and impressive feedback from other audiophiles when listening to my system.  The amps are in my brother's system now and are sounding awesome there.

I have the PS Audio M700s and think they sound amazing across the full range.  Have had class A/B most commonly.  Upgraded from Rotel class D most recently.  Ps audio provided much larger sound stage superior detail and imaging super tight powerful bass and smooth mid to upper end.  Light weight low heat less energy use massive power reasonable cost were my motivations.  They deliver.

I am a Dealer who has sold quite a few amplifiers.
I am in Love with the Jeff Rowland Model 125. Amazing Amplifier.
If you have any questions, Please let me know.
