I took the plunge - PS Audio Stellar DAC and S300

Anyone compare the following Class D rr D-hybrid amps:

PS Audio S300
NAD M22
Audio Alchemy DPA-1
Rogue Hydra

Curious as to the relative merits/demerits of their various tube and solid state input stages as well as Hyped UCD vs Icepower ASC300 vs Ncore as well as the variant approaches to feedback and servo control in the above.

Have owned the NAD, own almost every other Audio Alchemy device made at present, and am acquiring the S300, at least temporarily. Have had numerous speakers recently, likely keeping Silverline Minuet Grands just received.

Thanks for any input and experience sharing.

@jdaun @goldprintaudio Thank you both so much for your perspectives on these amps; really wonderful to hear of their relative merits (which are not inconsiderable). Now having actually heard them in comparison, granted in different systems I know well, I would agree that the M22 is better defined, considerably more at ease, and more neutral than the S300, whose tipped up treble does, however, grant it a greater sense of liquidity and a rather amazingly deep soundstage.
I am curious about the Rogue hybrids, having only heard the M180s in my system, but think that - after all that – I am at my end game with an LFD LE V+, unless I can move into a considerably more tube-friendly household/listening routine in future. I do trust @goldprintaudio 's indications re: the Rogues and value.
