Tbg,
I've done some pretty effective "horse trading" here on Audgiogon. :-) I now have a Bel Canto S300 power amp (150 w/ch into 8 ohms) fed by a Manley Shrimp tube preamp. Should be plenty of current. I'm just not sure how I'm going to speed break-in, which I understand they need a lot of. My wife's home office is above my listening room, so I can't just run them all day. So break in may take quite awhile.
