Audio GD XA150 Monoblocks

Does seem like a lot of earth-hating amp for the $ though relative to the likes of Pass, Clayton, Gryphon, Boulder, etc.  I hope he at least puts a low-bias switch on this monster. 

@noble100 — thanks a ton for reminding me of the D-Sonic amps.  They are now highly back on my radar. 

Hello soix,

      I have no association to D-Sonic, just a big fan that knows they deliver excellent hi-end performance at a bargain price in my system.  I suggest anyone thinking of buying an expensive hi-end amp or amps should try out a pair of the M3-600 or M3-1500, on a 30-day free trial,  before spending that much more money. 
     The 6 Moons review is a very accurate description of what to expect from them.  I feel very fortunate to have found such bargains.

His Master 2H looks really good. It has compared well with way more expensive soulution and CH precision amps in a review.

According to their site, they consume 700 watts together. That's 350 each mono. My previous Lamm 1.2 Reference monos used 320 each and were rated at 110watts. 

Agreed that if you care about heat production and electrical consumption, then class a is not for you. That's going to knock a lot of very successful and high performing amps out of consideration though. 

In my mind these amps should really be compared to other performers within the high power, double down class a topology. I'm not saying class d isn't worth considering, just that it is very much an apples to oranges comparison.
