Thanks for your responses.
I've heard good things about Onkyo and will certainly take a look at them.
While I appreciate the offer, RW, I do think that I will be best served by looking for something that will handle current and coming technologies in video, as well as providing good audio.
Once the pre/pro situation is sorted out, I will look at replacing the speakers. but, clearly, that has to come first since, no matter how good the speakers, a bad signal will cancel their effect.
