ClassDAudio.com product...any owners can input?

OK, so my old McIntosh MC250 is showing its age and making all kinds of noise thru my speakers when it is on but the rest of the system is not. This is one of those units that does not have an on/off switch. Ive run it that way for probably 15 years with no issues. Anyway, I am taking it off line and thinking I will buy a new power amp and get off the "vintage repair circus ride". While I love the amps warmish sound especially after it was updated by Terry DeWick about 15 year ago, it is as old as me (SS age) and it costs me $350-400 round trip to the US Mainland for repairs. So, I am looking for a replacement power amp. Runs alternatively update Ohm Walsh 2s or Kef R300s in a 15 x18 room with arched ceilings. (May be updating the Kefs to R3Metas in the next year but that is secondary now.) The 50+ watts on the amp has been fine for the volume I listen at. It is preceded by an upgraded Acurus R11 preamp and Sony ES SACD and Wiim Ultra. I am inclined to stay with separates for this system and am curious about whether or no anyone has tried out the CLASSDAUDIO.com power amps. I have seen some discussion of these here but it mostly seems to be older. I am looking at one of the GAN amps with 150-200 watts. It is not pretty but I dont care. I am just curious as to what people feel about its sound signature. The last D amp I heard was a Rogue Sphinx v3 I setup for an older friend on Kauai. I was surprised at how good that sounded. One longer term direction could be to get a D power amp and then join it with a Rogue rp3 or one of their other tube preamps. That seems to be a thing these days. Appreciate any input. Mahalo.
