I'm a long time two channel guy who is thinking of adding 5.1 capability. Currently I have a Parasound P-5 preamp running into a Marantz MM7025 amplifier.
The Parasound has a pre/pro input, that, when selected, shuts down the preamp's controls and uses the pre/pro. My idea is to get an NR1403 to use as the pre/pro, run its outs into the Para unit, and use the surround and center speaker outs for surrounds and centers. I would not hook up the front L&R speaker outs on the NR1403. Would this work, or do the front L&R speaker outs in the NR1403 need to be hooked up?
