Audio GD XA150 Monoblocks

     I'd check out the 2020 M3-1500 version of these monos before spending more on those: https://6moons.com/audioreviews/dsonic/1.html

     All similar performance but about 1/4 the size, weight, electricity consumption, excess heat and retail price of those dinosaurs.

     They each consume 700 watts constantly when in operation, which is  a lot and this is mostly converted and wasted as excess heat.

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.
