I'm using a Nelson Pass designed Forte model 3. 200WPC into 8 or 400 into 4 ohms. I switch to two Emotiva XPL-1L monoblocks 250W-8 / 500W-4 each. I like these the best of the amps.
They can also run in Class A to 35WPC otherwise. They are A then AB after 35W , auto switching. Thinking of using the Forte for the rear driverss (whenever that happens)
