I had a 50s and it was absolutely a great little amp. I sold it because I didn't need a ss stereo amp, but that was likely a mistake. IIRC, when I was shopping, the dealer (Sound by Singer) demoed the 50s vs one of the bigger Krells (may or not have been the 200s) and we both agreed that the 50 sounded significantly better.
Long time ago, so take it FWIW.
Good Luck
