Amp to power Model 2 Vandersteen speakers

McCormack.

What pre are you using? I have 2CE sigs and am using a Tube Audio Design 150 ($900) and a Tube Audio Design 60($900-1300). You can pick up a used McCormack DNA-1 for around $800 but, I found that the TAD combo here is superior..

Generally speaking, I think Vandy speakers perform best with high-current amps. I have been very pleased with Bryston amps, having used them with my 2CE's, 3A's, and currently 3A Signatures. A used Bryston 4B-ST (rated at 250 wpc, but typically closer to 300 wpc) can be purchased for around $1200.
