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

     No problem.  
     I think the biggest news of this thread is Atmasphere's upcoming introduction of a class D amp that will likely eliminate dead time with new circuitry that has a patent application pending and doesn't even require the use of the new GaN FETs.

    Things are progressing so rapidly in class D technology gains that the answer to this thread's question, which class D?, may be to just save your money and wait a while..... the answer will likely change, in absolute terms and probably especially if the price/performance ratio is considered.

tweak1,

Forgot to mention:
     I think it’s very interesting that your getting PS Audio 700Ms and the gaincell dac/pre at a great price.
I’m always interested in learning about others' experiences and views on class D amps and other equipment. 
     I find the 700Ms particularly interesting class D amps because they use what PS calls the 'gaincell'.  This is a fancy name for their proprietary, fully differential, zero feedback,discrete class A MOSFET input stage.  These amps don't utilize the new faster switching GaN FETs but, from the reviews I've read, they're high quality amps that will likely further improve the sq of your system. I'm not as familiar with their gaincell dac/pre but plan to read up on it.
     I know it's always exciting to install new equipment in one's system.  I wish you the best and look forward to your reports on the results.


Enjoy,

Im excited about the PS kit. The amps are ICE POWER tech. The input is proprietary, but the Gaincell is a volume module based on a B & O design. There are a number of in depth reviews on the net. I asked Paul McGowan if they are dabbling with GaN. I don’t think he knows what the digital department is up to in R & D though. I also asked him abut an external PS for the preamp, as he often does that, but he said that it wasn't needed. Hmmmm.Time will tell

What I am most excited about is I finally scored an AA power supply for the dac/pre, and it's a beast. They are hard to come by as production has stopped on the AA kit. I will have it Friday. No sure whether the PS kit will get here then too

     I read the Stereophile review on the PS 700Ms and it was very positive.  The review was from Jan./2018 and the reviewer had just previously reviewed the AA DPA-1Ms.  
     He thought the PS 700Ms were superior and even compared them to being somewhat similar in sound quality to the Theta Prometheus mono block class Ds that go for $12k/pr, saying they were a bargain at about$3k/pr and you said you bought yours for even less.
     He also thought they performed best when separated on isolation stands and not stacked on top of each other.   Here's the link:

     If they sound as good as they look, these amps should sound very good.

Enjoy,
