Several 'goners use SMc modified McCormack DNA amps with the Vandy 5's with excellent results. I believe Steve uses Vandersteen speakers to voice his amp mods, although I'm not positive about that. There is some serious synergistic mojo happnin' with those amps and speakers. The dealer that sold me the Vandy 5's also sells ARC and he agreed that the moded DNA-225 outperformed a freshly retubed VT100MkII amp with those speakers. I think you'll hear from others here about their experience with Vandy & McCormack mods. The Quicksilver tubed amps also get high marks with the 5's, but I suggest you follow Agaffer's advice and try your Pass amp before considering changing amps.
Amplifier for Vandersteen 5A' s ?
I recently had an opportunity to listen to the Vandy 5a's and was really impressed. I currently own the Pass X-600's and think they do a remarkable job with my Magnepans, but if I buy the Vandys I would like suggestions on other amps that mate well with the speakers. Tube or SS, and preferably mono's. The budget for the amps should not exceed $6500 used. Thank you much for your suggestions.
