Try the Forte' Model 3(a-b, high bias), I saw one on AG about a week ago for about 365.00. It's the little brother to the Threshold. And a smoothy of an amp,for the price.Careful you run good cables though.THe Audioquest GBC which runs for 100.00 new off hcm audio.com. Is a decent budjet cable, ok bottom end but not great. I used a Forte' to power a pair of Thiel cs2's.There are plenty of good used amps you could choose from but for 365.00 if you can find it. THe forte' is a great buy. I wish I still owned one.you can't beat it for the amount your look'n to spend. It's a work horse of an amp 100wpc e-z!
