If you can handle +/-$1500 (new on E-bay), the Harman Kardan HK990 integrated amp might be the best answer. It's a 2.2 channel integrated w/150 wpc from a high quality power amp section derived from a Matti Otala (Citation, Electrocompaniet) design. It also includes the digital bass management (x-over, etc.) and digital room correction features that are more typically seen in multi-channel AVRs.
Another choice comes from NAD, which has just introduced its own version (sorry, don't know the model #) of a 2.2 channel integrated with digital bass management. However, it looks like their version lacks the auto- room correction (I think it offers manually operated digital EQ, it wasn't 100% clear from the info I saw) and will cost +/- $1K more, since the list price is app $500 higher and it isn't yet discounted (AFAIK).
