thinking selling anthem statement p5 ideas?

If you have been following my last few threads i have questions about pre amps and amps.
currently i have....
b&w 804s fronts
b&w htm3s center ( just found one!!!!)
b&w cdm1 sides and
b&w 602 rears.
old sub by cerwin vega.

my room....
25 by 25 open but i only use half for dedicated home theater.
Commercial carpet floors and concrete block walls with dry wall over.

equipment....
play station hdmi
pioneer elite 92 txh ( only amping the rear 6 and 7 channels) pre outs to
anthem statement p5 via shielded rca. about 9 ft in length.

so here's the thought
1. how much can i get for the anthem and pioneer? pioneer is perfect and the anthem has a few scratches on the top cover( not from me).

2. what could i buy for the money made on the two pieces? processor and amp or amps that is.... and would it be a great enough upgrade to go through the hassle?

i would need the hdmi in the processor with xlr connections and at least hdmi1.3 for a dolby truehd.

the ones that keep coming up are the marantz and the integra for processors. if there is other ideas that would be great.

and what to do for the amp or amps... i love how the anthem makes my speakers sound... a lot less bright than with the pioneer.

so... what are your thoughts?

thanks,
Bill
