I gotta bump this thread and reply just because I have one and love it. The 9833 is probably one of the best CD/MP3 players Alpine has ever released.

Motorized face plate.
3 4v outputs.
5 band eq
3 point xover.
Time alignment
Rotery nob
Ability to control the MRV / MRD amps from the head unit.
Ability to play CD, CDR, CDRW, MP3 discs and WMAs. Aux input with adapter.

I know on ebay they were going for $250+ WHEN YOU COULD FIND THEM.

Right now, if its in GOOD condition, its worth $250 compared to the new crap alpine is putting out.
