I didn't like the Kuzma much but I'm sure that Bub can rest easy that the SME 30 is miles worse and the 20 miles worse still.
I was a bit underwhelmed by the Kondos. I preferred the cheap (18K) preamp to the expensive one (which may have been broken) and the Dynavector power amp (with the cheap Kondo pre) to the Kondo power amp. And with the LV I marginally prefer an A21a to the DV. I think I could buy 100 Sugdens for a Kondo pre/power.
All this leaves me confused as to whether I like valves or not - I liked Mic's.
