High End Amp Price Collapse musings

I will stay with my tube monoblocks.  

I'm still a purist when it comes to the different classes of amplifiers specially when you design amplifiers from tubes, darlington transistor and mosfet using manufacturer handbook.  I still prefer Class A and A/B amplifier stages it has better sound when you have the proper speaker gear to match.

I sold my Audio Research tube gear about 8 months ago and replaced it with a full set of Peter Madnick's Audio Alchemy equipment. I really like it. Some of you must have seen the review below...thoughts?

I didn't see any mention of the relatively new NAD M22 amp (using a variation Hypex NC400 NCore modules).  It's had some favorable reviews even compared to amps costing 3x as much.  Any experience here?  

I had a Bel Canto EVO up til about 5 years ago - I preferred it in my system to my other class A and A/B amps but I never had a $10,000 amp in my system of A or A/B.  I recently bought the NAD M22 and am in process of putting everything together but in a short listen I preferred it to my Adcom GFA555II (the one designed by Nelson Pass), which I thought was excellent.  I bought the NAD here second hand so it is broken in.  I'm picking up an Auralic Vega today and am excited to hear the combination of it, my NAD amp, Rougue (tube) preamp, and some digital files.

This may sound blasphemous on this site, but I bought a 50Wx2 Tripath Class-T amp from China for a small system in my office and am amazed how good it sounds.  (Note: I have McIntosh separates in my man-cave and Krell in my living room, so I am not blowing smoke here)
