@daytrader bass got faster but everything else, (ie, what I call tube magic) was lost. Class D has its place in my opinion, just not in a critical listening environment when the life of the music is most important.
+1, yep, and the difference is notable when comparing to good tube amplifier designs and tubes. Getting closer but not there yet [in most cases]. A few designers claim to be as good as or better now with Class-D, and hope they keep working at it. Will be interesting to see more Class-D powering all parts of the main speakers [not just low freq] showing up at the shows next few years, as tbd.
