I don't mind them so long as I can't hear them. And good ones with good control are silent.
I like the fact that it is a fully balanced design rather than single-ended (with balanced to single-ended conversion of balanced input signals).
Shame there isn't a pic from the side. What I find interesting is that it appears to show the supply secondaries running alongside where the amp output transistors would attach to the heat sink. That plus the amp itself (IPS/VAS stages on the outside, output stages towards the centre) seems so close / integrated with the PSU.
