Thanks for the "assortment" of opinions. I think I found out what I needed (no to a Sony amp, maybe to the SACD, definitely to a digital camera )
The KHorns I found are 1980s with the AA crossover, so now I am learning and in search of tubes! Should be an adventure!
Anybody got any thoughts on the Quicksilver Audio monoblocks? I may have stmbled across a deal on a pair..
