The view from the cheap seats:
Comparing a BAT amp to class D is like comparing Quintarelli Giuseppe Amarone Della Valpolicella Classico Riserva 1995 to Chianti, a very specific flavor to a broad range. Implementation is more complex than Hypex vs. Icepower, just as all class A/B amps don't sound the same.
For what it's worth I recently upgraded from a modest Class A/B integrated to a Primare I32. I am very happy! That being said, I am a detail fiend. I use the Primare to drive Canton Ergo 3 way towers; which are also very detailed.
