For years I have been into tubes and still love them, but my current financial situation precludes me owning a tube amp. I have Omega Compact Alnico Monitors and the only amp I have is a TPA3116 that I had put in a nice chassis, so being it was all I had, I set up my system with it and love the sound. Great low level dynamics, texture, speed, and imaging...and enough power if I want to listen louder.
Back around 1990 a salesman in Sound Hounds in Victoria, B.C. said regarding audio gear "if it sounds good, it is good". Regardless of price, if it sounds good, it is good. NAD proved that with their 3020 decades ago, and are doing it now with their Class D replacement, the 3020D & D2. Bob Brines of Brines Acoustics who is highly respected on AC uses a TPA3116 based amp among others.
Back around 2013 I tried a small Class D amp and hated it so much I returned it for a refund, and never took Class D seriously until Wind Chaser had me in his home to hear his excellent sounding Class D based system. On top of that, he gave me a brand new TPA3116 board to play with, which is the amp I currently have in my system. Thank you John.
