The PRS pre-outs are too much for my Massive audio amp and shuts it off when I turn the power up. I installed the PRS 1 1/2 years ago for a week and it has been sitting in my room ever since. I dont really need all of the bells and whistles of the 880, and would like to have a moderately priced touchscreen. Is the AVH-P4000 the way to go?
