Amplifier for Vandersteen 5A' s ?

You can add used VTL sig450 to the list.

I have 5As and have been looking around too. Unless you are in hurry your Pass W-600s should work well.

I called Richard Vandersteen a while ago. After he realized I was serious, I told him that I had Pass Aleph 2s and that I was considering Theta monos. To my surprise he called that largely a latteral move (though he said the Thetas were really good) and that I should consider tubes. He thought tubes had the advantage of better image body (I forget the exact term used) over the best solid state.

Our conversation was cut short so I hate to say too much with out a more extensive talk.

But Vandersteens are tube friendly designs if you want to deal with tubes.

FWIW I have on my list at this time Quicksilvers (max value), VTL sig450 (used), ARC VTM200 (use, more $) and if I really go wild ARC ref 210s or VAC Phi 220s(if I can find a deal). If I stay solid state the Theta monos. Still looking, got a few months yet.

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.

Thank you for all the suggestions. I fully intended on trying the Pass amps first, however those 5's really don't need the power the pass amps have and in the process I could pocket a little change. I did consider the Mccormack. I used to own the DNA-2 Anniversary edition w/ an SMC gold revision. It was probably my favorite SS amp I've owned. I'm still calling myself a moron for selling it. I really need mono's, so the DNA-2 is out. I'm still looking forward to hearing from more members. Thank you again

The top two choices have to be a pair of Quicksilver V-4 Monoblocks or a stereo/mono pair of BEL 1001 Mk Vs. The BELs will outperform the V-4s. Try them and see!

I'm using an Ayre V1xe with terrific results. I understand the monoblox are also good..
