If you are looking to get something new, the Belles Aria seems to be getting a reputation for being a good match. I use the dual mono 85 watt x2 with the Quatro. Not a tube amp and not the one you mentioned. Apologies, if I’m off topic.
Vandersteen Aficianados please step inside (Quatro)
I've got my eye on a pair of Quatros. Would a 60 wpc tube amp comfortably drive these? Or would I be doomed to something in the SS category? Thoughts appreciated.
