Hi guys. Here is my dilema. Having trouble picking which receiver to go with. My system will be used for 95% music. I will have NHT IW3s for all my speakers (fronts, center, and surrounds). I know, I know, I shouldn't go with in-walls if possible, but other issues and WAF require the use of affordable inwalls unfortunately. Though I have listened to them and put them through a pretty punishing test at the local audio shop and they performed very well. I was quite pleased. So, I will have NHT IW3s for my speakers and I will have either an SVS 25-31 PC+ or the PB12-NSD/2 for my sub. Hopefully the latter. Again, WAF and fitting in with the family room furniture and set up will determine the final selection. So onto the receivers. Never in a million years will I use it in 7.1. It just isn't going to happen. 5.1 will be it. Almost exclusively music use with a little movie use. So I have narrowed it down to the SR 5600, SR 6400, and the SR 7200. The 7500 is pricey and out of budget, and honestly, I don't need or even know what all the gizmos and extras are no it (and the others for that matter). I want/need to be able to run speakers in another room off of it. And also my outside speakers. But hooking up the main listening room and one more room (just in stereo mode, no surrounds or sub for the extra room) is what is needed. Worst case scenario I can just get a speaker selector to run the other room and outside speakers. Need to hook up a VCR and a DVD player to it, so if the component video switching on the 6400 and 7200 is what allows to switch between the two, that would be preferable. Plus the 6400 and 7200 have a bit more power than the 5600. So what it boils down to, is bang for the buck and what I am going to use it for, should I go with the SR 5600, 6400, or 7200? And if possible, why? Also, do these have the ability to use a Coax to hook up the sub? Thanks! All advise and guidance is appreciated.
