Amps for Vandersteen 3a Sigs


My cousin is considering upgrading his 2CE-sigs to 3a-sigs... both would be used with a pair of 2WQ subs. Right now he is driving the 2CE's with a McCormack DNA 0.5 Rev A amplifier.  We are hoping this amp will be a good match for the 3a's, but are concerned it may not be enough power.  Given that the subs are relieving the amp of the bass frequencies, perhaps it is enough power. 

Thoughts on that combo?

Beyond that, looking into the future, what amps are highly recommended with the 3a-sigs?  I'm guessing that my cousin would rather work with solid state amps.

Thanks, Peter

The McCormack should be a great match but if he feels the need to change for more power the Odyssey Kismets are a great match with Vandersteen as is the PS Audio BHK 250.  Dave Clark of PFO is running the Quatro Wood CT with the BHK. I ran Odyssey amps with 2CE Sigs, 3A Sigs and Treo CTs.
Either something from VTL, PrimaLuna or QuickSilver amp. Vandersteen’s sound great with tubes.
Once he gets everything else dialed in, and he is satisfied and stable, if he gets the itch and wants some variety, I would set him up with Quicksilver V4's, possibly running KT150 tubes!  Always looking for the bang for the buck :-)
