Need some help!

Currently own a Panasonic Technics SA-5370 receiver and a pair of Wharfedale W 70's. I'm considering upgrading my receiver. Candidates include: Sui G5xxx, Marantz 22xx and maybe a pioneer. My budget is around $300. I would like opinions please.

I'm not an audiophile. I enjoy good sound though. Ebay appears to be my main source of equipment. There is very little selection on CL in my area.

Thanks

Hi, Wharfedale's don't require lot of power to drive them.

Older series of Sansui are good too.
