Ok, I'm looking at getting a complete ascend accoustics speaker set. 4 cbm-170s and 1 cmt-340c. I found a web site that has a refurb NAD T742 for $399.20. On the same site they have an HK AVR-325 for $525.13. Which sounds like the better deal? They are both 50wpc. The HK is a 7.1 receiver, which isn't really necessary for the size of the room I'll be putting it in, but could be nice for future upgrade ability. I'm not very familiar with NAD components, but alot of people on these forums recommend them. Will either of these work well with the speakers listed above, or do I need more wpc to push them?
