He is talking about a Premier only unit, it is the Pioneer flagship, and is pretty baller for sound quality, although the usb and ipod interfaces are the old school box style so very slow and not very friendly with all of the newer ipods, and also no bluetooth.
If bluetooth is a big concern the 7000 and 8000 have it built in and I could be wrong but I believe as of now anyway are the only ones using Parrot technology.
The DEH-P800PRS as he mentioned FTW. 4 volt, F/R/S OR low/mid/high, seperate left and right 16 band eq, burr brown dac's, and time correction.
