Sound advice from all, sorry for the pun!
I do plan on trying the Pioneer first. I'm sure, as it been pointed out, that I won't have any issues using just my receiver. While it's not top-of-the-line it has severed me faithfully for some time. While it doesn't support HD audio it plays well using PCM for 7 channel.
I have always wanted seperates and I will get there one day. Just looking for any info that'll give me an understanding of what to consider and look for when an opportunity/deal comes along. I used to be very interested in audio, years ago, and I'm now only playing catch-up.
Again thanks for all your help and insights!
