Jeff Rowland perfected Class D years ago. Amplification is just a technology, not bad or good. It’s what you do with it that counts.
iirc it was back in 2008 or 2009, someone talked me into getting a pair of the fairly recently (at the time) released pair of jeff rowland class d mono blocks... sure looked pretty with those 3/4 in thick milled faceplates ... but those amps were one of the most disappointing, grey and lifeless sounding pieces of gear i ever recall buying ...
i punted on them in less than two weeks
