Triode,
Awsome! A friend of mine has a has the same speakers, all though he has a couple of modded supertweeters form a local dealer on his subwoofer section, makes a very nice improvement
He also runs Italian amps only, Viva Linea pre. and the GRAAF GM-20 that's been discontinued which is too bad since thats the best amp using the 6c33c tube I've ever heard with AVG.
If you ever run into one of these on the used market, pick you can one up pretty cheap. Go to GRAAF's site check out the specs. Can't find any tube amp that can match it plus is it's 20watts OTL sound more like 50 plus. At under about $3,000 you can't go wrong! Ever think of cryoing all your tubes? Another big, rather cheap upgrade.
Can't beat the Duos though.
Happy listening!
