I'm new to the forum and would appreciate advice about prewiring for a whole house distribution system and a theatre room for a house undergoing a total remodel. I am mainly an audio person and have purchased components with that in mind. This is my first foray into home theater and I want to do it right. I am upgrading from a 2 channel system, so most of this is totally foreign to me. I am interested in using a multizone receiver(s) to run the whole house system. I have 9 pairs of Phase Technology CI-40V in-wall speakers and 2 sets of Phase Tech Spacia speakers that I want to use in separate rooms. I am considering using the Niles ZR-4630 receiver(s) with the Intellipad Ci Solo and Numeric keypads. Would it be best to use two receivers (6 zones each) or one receiver with a 12 channel amp? I am also open to other systems, but want something that is very user friendly. I am using Ixos 14/4 speaker wire for the whole house system. For the home theater/stereo system I have B&W 803s for the front and 805s for the rear and a HTM2 center. I have MIT Terminator 2 bi-wires for the front. Is it wise to bury this in the wall for a clean appearance or should it be left exposed from the receiver if possible? What would you recommend for in-wall wire to bi-wire the rears? I have a Velodyne HGS-15 sub. How should this be wired? My local installer suggested RG-6, but the manual says to use speaker wire for a speaker-level connection to my receiver. The instructions are also showing that you should go from the right and left sub outputs to satellite speakers. I don't understand this because I thought the rear 805s should be bi-wired from the receiver. I want to hear the musicality of the system, and not let the sub override. My main focus on the theater will be concert DVDs. I plan to continue using my Denon DP-47 turntable with moving coil cartridge. Can you recommend a good unit that will make it work with the new receivers? Thanks for giving this novice input on doing it right the first time!
