integrated amp recommendation needed

The Plinius 8100, 8150 and 8200 are excellent if you can find one in your price range. They are getting a little old, but should still be good for at least a few years.  If/when they need the caps replaced,  do it and still have a good,  inexpensive amp.

I liked the Cambridge suggestion above. Anthem isn’t bad and someone’s got a MCA-2 for $550 right now. Bend the budget a tad maybe and pair it with a simple pre-amp and you’re set up better than an integrated.

For those suggesting Yamaha (a very decent choice and match for your speakers) look at audiocircle.com. There is a A-S801 for a great price. Don't know what kind of transformer or caps, but I am sure it will sound fine.

revel needs a lot of high-current juice, which i'm not sure the yamaha or lower cambridge will provide. i've had vg results with parasound or, if you can find one, acurus dia100 or 150.
