Pre/Pro with 2 MCH analog inputs plus..

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.

The Bryston SP-1 (or SP-1.7) has multiple 2-channel analog inputs for stereo redbook CD player, 2-channel output from your SACD player (most/all SACD players have one set of 5.1 and one set of stereo analog outputs), or even FM radio-tuner and vinyl turntable. There is only one set of 5.1 analog inputs--this set of inputs can be used by only one set of 5.1 analog outs from a 5-channel SACD player or your DVD-Audio player. The 2-channel bypass and the 5-channel bypass modes engages the Bryston's "2-channel analog preamplifier" or its "5-channel multichannel preamplifier" --bypassing all digital processing of the SP1 (1.7)
