I auditioned the DSP 5200s and a DSP 5000 center at home this last weekend -directly comparing to my N804 + Meridian G57 amp.

A consistent picture emerged.

1 Trifield is great
2 DSP 5200s have great bass, drive, rhythm and much better in room bass extension and volume. Very good imaging.
3 N804s have much better upper mid and treble - very much smoother on female vocals and more delicate on cymbals. Also less boxy/ more open.
4 configuring G91 and DSP speakers is a pain and not repeatable. Buggy software? But the cabling simplicity Vs multiple lengths of bi-wire is very appealing.

These differences were not subtle.

Guess I have to audition the B&W 803D now to try to get better bass the B&W way before deciding. DSP 6000/7000s are too pricey. Asthetics of 5500 do not appeal.

I wish B&W would buy Meridian and combine their speaker technologies. That would be great.
