Consider a multi-channel preamp. The EMM-Labs Switchman 3 (if you don't mind a wired remote) or the new Audio Research MP1 come to mind. You get 3 or more sets 5.1 multichannel analog inputs from multiple sources: SACD, DVD-A, and even your SS-Processor. The MP1 has a processor pass-thru with unity gain, allowing a home theater processor to control overall system volume (by connecting a pair of amps/speakers to the processor output you achieve 7.1!). Just received my Audio Research MP1 Friday but haven't had a chance to set up yet. Sources include the following: Lexicon RT-10, Sony C555ES, Denon 5900 into Lexicon MC-8B. All speakers active: ATC ASL100 (3), ATC ASL 20 (4) and ATC C-6 LFE. Ray.
