I have a pair of ESLabs DX-S4 which I've been happily using for over 5 years, although one is broken due to a mouse pissing on the board when I had the top off! I'm using one in stereo mode to drive my Maggie 1.7i's, and it sounds really good. I've compared it with several other well known, high class amps, Class A/B and A, and it sounds better than amps costing several times the price of the ESLabs which when they were new, were about £1750 each. They're probably 15 years old now, but still sound great. ES actually call them Class T, as they use a Tripath module to drive two pairs of MosFets - one pair per channel, at 180w into 8Ω, 300 into 4Ω and 200w into 2Ω. In bridged mode it gives 500w into 8Ω using all four output devices, and double the current.
Ignore people who say Class D is rubbish, as they've probably not even heard any!
