KR Audio Integrated amps

Anyone have any opinions good bad or ugly on the KR Audio Integrated amps?
which model you are looking for? I have had a few....even from the first series and only for some tube failing on me once, they been working perfectly. The best is Kronzilla, just a bit expensive to re-tube....
Prcinka, I'm looking at the Kr Audio VA340 MKII or the VA 350MKII
I have a VA320 "Baby Kronzilla" Not an Integrated, but a stereo power amp that puts out 20 wpc of class A power via the KR842 tubes. It controls my 89db efficient Kharma loudspeakers in a medium size room (16.5 x 23 x 10). I am very happy with the combination.
