If you have the opportunity to audition some other tube amps with the 5A's, then I would add the following to your list: Conrad-Johnson (Premier series); Manley Labs Neo-Classic; and VTL.
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???
