Better add the Belles 350A Hot Rod(up to 6 channels) by Power Modules, Inc. to your list. Their 150A Hot Rod amps have recived unanamously spectacular reviews and the 350A trumps it easily.
To quote Doug Blackburn's 10/01 Soundstage Review:
"The Belles 350A is the amp for audiophiles who want super-amp sound on an under-$4000 budget. It is a no-nonsense, yet well-finished amp whose sound is that of the recording unaltered. The 350A is for connoisseurs of accuracy and faithfulness to the original performance as it was captured to LP, CD or one of the newer high-resolution formats. There are no added colorations, no weaknesses that hide behind hyped detail or sweetened sound, something surprisingly few amps at any price can deliver. The 350A has a killer bottom end, and its incredible rejection of back-EMF from the loudspeaker ensures sound quality that is as true to the source as may be possible with current technology.
It doesnt happen often, but every now and then a reviewer is lucky enough to encounter a product that is so perfect that it is difficult to imagine anything being better in any substantial way. But what is unusual about the 350A is that it achieves this at the lowest price point Ive yet encountered. The Belles 350A is an instant classic, and if there is any justice, it will sell like hotcakes. It's definitely this reviewer's choice."
