Yeah, you can use a temporary monitor to aid with the setup. I've never done Audyssey without a monitor, but you may be able to do it with just the LCD screen on the Pre-Pro.
So the Marantz AVR is for movies and this new setup would be for 2.1 music?
That means you'll sell the Marantz 8005 and the Parasound P5?
What's the other option? Just use the current Marantz 8005 and not use the Parasound or ATI?
You just have to look long and hard and ask yourself what would really make you happier?
You know your current Marantz 8005 gives you the sound you want. That's the reason you want to stick with Marantz.
Everyone is different. But it's not about everyone else. It's about you.
For me, since I've already owned high-end separates and been-there-done-it, I would just get an AVR. I'm kind of boring. I must be getting old or something.
For someone else, it would be the Marantz Pre-pro + ATI AT2002.
For someone else, they would clean house and sell the Marantz 8005, Parasound P5, and AT AT2002, and then just get the PM14S1.
Just got to look long and hard deep down.
