Good amp match for vinatge Vandersteen 2C's?

McCormack!

Because the McCormack's tight, punchy bass compensates for the Vandersteen's somewhat bloated bass, the McCormack's somewhat forward presentation compensates for the Vandersteen's somewhat laid back presentation, the McCormack's liquid midrange through treble works very well on the Vandersteens (the Vandersteens though very forgiving through most of this area, do have a narrow area in the brightness region, that can be less forgiving). It has been rumoured that Steve McCormack uses Vandersteens. Considering the very long period of very active sales of the Vandersteens, that would seems like a good idea. Two of the best values in all of audio, and they work just great together. What could be better! The Vandersteens work very well with other gear too. At the value end, ss amps like the PSE's (though I'm not sure of that companies current status, and their older gear might be getting long in tooth), and at the higher cost end, Audio Research. Despite the enthusiasm by some here for tubes with Vandersteens, I'm less convinced that tubes are best with them, especially in the bass. There are some tube exceptions though, such the previously mentioned Audio Research. All in all, I think the McCormacks offer the best sound for the buck with Vandersteens.

The Thresholds should work nicely. IMHO, the sound of the Vandersteens work a little better with the sound of the McCormacks, you might feel differently. As was previously mentioned an older amp might be due for a refurbishing. That might come with a cost. All in all, with the Vandersteens, I think the McCormacks are the bang for the buck value leaders, all the while not having to make any apologies for the excellent sound they make together.

Rather than the load, I think the sonic signature of the Vandersteens: ripe bass, a bit of a peak in the lower treble and rolled off high end, resembles classic tube amp sound, which might suggest that one might want to avoid doubling up on those characteristics. I think the classic "High Definition" sound of the Audio Research amps are bit different than is typically found on many other tube amps. To be fair, the forward upper bass through mid-range often found on tube amps, can compliment the somewhat laid back sound of the Vandersteen's in that frequency range, more so than the typical withdrawn mid-range of many ss amps. Which is why, and please forgive me if I repeat this again, I think the somewhat unusual forward mid-range ss McCormack amps might work so well with the Vandersteens.

Ah, I do miss the Audiogon edit function!
Another thing to consider is that we're talking about an older pair of Vandersteens here. Tube amps usually cost more than ss amps. I don't think it would be prudent to spend a lot of money on amplification in this instance.

Caveat, I know nothing about the seller, or these particular pieces.
