I've been through a few:
SWR, all valve (x2), Euphonic Audio, Genz (x2), EBS, Trace Elliot, Glockenklang (x2), plus several combinations of pre/power amp.
The one which ticks all the boxes for me, and I can't fault at all is the Glockenklang Blue Rock. I've never considered anything else since getting this amp. As you might expect, it's expensive, and has gone up by around £200 since I bought mine due to the weak pound
Still, for me this is the perfect amp.
