Pro PA Amp Recommendation

A fellow audiophile friend and I are amateur musicians and are looking to buy a power amp and PA cabinets for use in a basement and light outdoor settings. (We have a mixing board and effects already.) Do any of you other audiophile/musicians have any recommendations for amps and speakers for this applications?

We are looking to spend around $1000 for the combination and sound quality is as important to us as quantity. We also don't need extremely heavy duty stuff since we won't be hauling it all over the place on a regular basis.

Thanks for any ideas.
