RE: Who makes GaN FET Amps ?

Posted by AbeCollins on July 19, 2023 at 10:44:56:
I had the PS Audio M700 ICEpower monoblocks that I thought were excellent. They were "voiced" pretty much to my liking. As with many PS Audio products they have a slight warmth with robust and dynamic midbass and are always the opposite of lean or thin sounding. They're never bright but possibly not fully extended in the treble. The M700's additionally produced better bass definition than I've heard in my previous but old favorite Wyred4Sound SX-500 monoblocks. I have also tried Hypex UcD and nCore amps that were not very good sounding IMHO.
Fast forward to July 2023 and I've been playing with the Purifi Eigentakt NAD C 298 stereo amp. Amazing! It's incredibly smooth without losing detail, more transparent than the M700 w/o being 'etched', and the NAD delivers just enough midbass and midrange robustness plus extension up in the treble w/o being bright. It is not lean or thin by any means but it appears to be more revealing and even across the board vs my previous PS Audio M700's. Both are excellent but different.
I'm pretty impressed with Purifi Eigentakt Class D as implemented in the reasonably priced NAD C 298 stereo amp.
That being said, I'll wait for a few major [larger] companies to commit to GaN FET designs and let those mature a bit longer before I jump in.
