Van Alstine Synergy integrated: How does it rank ?

If you bought the Van Alstine for duress get the Double MOSFET option
For$99 much more current,and dynamics,and detail,and it run cooler.
As long as you don't need to go to 2 ohms you a refine.
Modwright is 2x + the money on a used market a steal
Or the $3,000 Signature integrated Underwood Wally has
A great integrated for that price.

The AVA looks like a good, solid integrated. Not sure how it ranks with the others you mentioned - there is a recent review: http://www.enjoythemusic.com/magazine/equipment/0414/audio_by_van_alstine_synergy.htm

Buy a used Modwright a great integrated, can be bought for under $3k
IMO the best Integrated if you like a warmer perspective with plenty of power.
