Rogue Zeus is the ultimate, but Rogue 120 monoblocks will drive 5As well and easily. They have powerful tubes.
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???
