Another one to consider might be 2 strapped Berning zh270's. I have heard that one works quite well with the 5A's although I haven't heard first hand. Two would provide more power than I could imagine you could ever use with this speaker along with ultra clarity. For complex orchestral and choral music this amp is completely unflappable. Of course if aesthetics are also a consideration, you may want to look elsewhere.
Best monoblock tubes amp with Vandersteen 5As
What is the best sounding monoblock amp for the Vandersteen 5A's at moderate listening levels in a 12 x 25 foot room with 9 ft ceilings, hardwood floor? I have heard them with Cary and Quicksilvers. The Quicksilver V4 sounded very good but what else will sound even better???
