I am assuming you are looking for an integrated?
You couldn't go wrong with the 585.
If I was looking for an integrated in the $7K range, the Luxman L-509X would probably be my first choice.
If you stretch the budget a little bit, you are also in striking distance of a used darTZeel CTH-8550 which would be top shelf.
If you are wanting just a straight power amplifier, a number of other things come to mind...Rowland 625, Krell 302e, ARC Ref 75SE or REF 150SE. All these would work great and can be bought used for pennies on the dollar.
You'e made a great choice with the 228BE. I had 208's for an extended period of time and now have had Salon2's for a few years. Haven't had a chance to hear the 228BE or 328BE but I'd sure like to......
