Pre-Pro Suggestions?

Hello,

My modest system includes the following:

PrePro - Parasound DSP 1000
Rotel CD RCD-855
Oppo 970HD
Front - Sonic Impact (7.5 Wpc) - Klipsh KG-4
Rear/Center- Mondial Acurus 100 Wpc- Dynaco A-25 / Center- Athena C-5
Sub - Dali S-12
TV - Sony WEGA 32"

Room 9' x 18' seating against the short wall

Let me also add that I am more interested in audio, than I am in video. So long as I can fully control center channel volume for dialog, I am generally happy with what I can get now from the system.

Over the last few months, the Parasound has finally given up the ghost and I am left with barely any sound stage width and generally degraded sound, as starkly revealed when the Acurus is turned off.

So, I am looking for a replacement pre-pro (or receiver with pre-pro option.)

I would like to spend around $1000, although I can spend more, if necessary, for a significant bump in quality.

Given the limitations of the room, budget and existing equipment, I understand that options may be limited.

Any suggestions would be sincerely appreciated.

Thanks in advance.
