A/V Receiver for B&W matrix speakers


I’m trying to convert my stereo system into 5 channel HT. My current system comprises Toshiba SD-9200 DVD player, Audible Illusions L2 preamp, Musical Fidelity A3Cr amp and B&W 802 matrix speakers. I’m planning to use HTM matrix for central channel and 804 matrix for surrounds. I’m thinking about either buying AV receiver for processing signal and driving center speaker (not a very bright idea) and surround speakers or buying processer/preamp and three channel amp. I’m not sure if I really need processor since Toshiba has a built in digital processor.
I don’t want to spend more than 1k and at the same time I need the system that would allow me to listen to my current setup without switching cables.
Any thoughts?
Thank you.

Pdn, Gaw, Kewadinbob,
Besides the number of channels and power output ( I presume they both have A/B type of PAs) what is the difference between SR18 and SR8500. I mean video and audio signals processing capabilities?
Can I bypass Marantz audio processing circuit feeding my DVD player into preamp via Marantz?
Gaw, you dont have dedicated 2 channel preamp you are using SR18 preamp for stereo right?
The SR-18 is an older surround sound receiver than the SR-8500. Both are discontinued products from Marantz. The SR-18 specs claim this unit puts out 140 watts RMS from all 5 channels into 8 ohms. The SR-8500 is rated at 125 watts x 7 channels into 8 ohms. But be careful with the later Marantz models. I had a conversation with them directly recently. It seems on their current line of 7 channel A-V receivers, the stated power rating are for two channels driven. When all 7 channels are driven, they guarantee only 70% of the stated power rating in watts into 8 ohms.

When evaluating any new A-V receivers, be sure the specs states "all channels driven" at the same time.
No the gryphon amp I am using is an integrated so no problems setting output levels for the front speakers. the setup has the marantz front pre out feeding a input on the grypyphon. The main reason for this setup is I want a dedicated hifi system using my higher end cables etc etc and not having to run the marantz for my music. I have used the marantz all the way around and for home theatre sounds great and drives the 801 without problem but just not the same when listening to music.
