I bought the D-Sonic M3a-800S (2 x 400w) last year and haven’t looked back.
I went through two class A/B SS set-ups over the past 10 years--a NAD M3 (good built quality, sound was too muddled for my tastes) and a Bryston set-up (BP26, Byston DAC, 4BSST2 power amp--wonderful, solid, totally neutral and dead silent). Have also cycled through various speaker set-ups, Dynaudio, Paradigm Studio and Signature series, Magnepan 1.7 and 3.7s.
The Bryston set-up with the Magnepan 3.7s was supposed to be my retirement system, but when we reduced our living footprint, my listening space dropped from a 30 x 50 living room to a 10 x 12 a pocket office.
Long story short--sold off my Bryston gear and replaced it with the D-Sonic amp coupled with a passive pre-amp from Luminous Audio driving Legacy Studio HD monitors. Near-field listening only given the space constraints...
I’ve been totally impressed with the D-Sonic--dead quiet, dynamic range, fast, neutral (maybe to a fault), and of course no problem driving my Legacy HD Studios (I love the AMT folded ribbon tweeters more than even the sound of the Maggie 3.7 ribbon tweeter). Build quality is first rate and the gentlemen who runs the business is very responsive both by phone and email.
Now to be fair, I’m 60 years old with hearing loss above 7K in both ears. I think this is fairly typical for my age group. And of course I’m comparing apples to pomegranates--my Bryston kit was connected to the Maggies and Paradigms in a large room--my D-Sonic/Legacy set-up is barely 7 feet away from me.
Still, for the kind of music i love, jazz and classical piano, string quartets, female jazz vocals, etc, and given the cost to find out, couldn’t be more pleased.
