After a number of various switching amplifiers through the 2000's I found a pair of early Hypex NC400 kit amps to be noticeably preferable in the mid and upper frequencies. I use them for recording playback with monitor speakers. I still use tubes for listening.
I haven't followed Mr. Putsyes later models but I have noticed a number of speaker manufactures are using them for their powered systems. Interesting designer.
