Well, for your investment, you aren't at too great of a risk. the SA-12 was the first "high end" amp I ever owned, back in '87, and I loved it driving my Vandy 2C's. I was tempted to move up to the SA-20, but just never took the plunge (I remember asking my dealer in what ways the 20 was better than the 12. He replies "Better in every way...." Ah, they know how to set the hook).
Enjoy!
