CDA-9835 //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif I've owned the 880PRS, 800PRS, CDA-9887, and currently run the 9835. Doing an A/B comparison between the 800PRS and the 9835, EQ flat, no TA done, crossover points and slopes the same, and gains matched, to me the Alpine sounds better. It really is a matter of preference though. Pioneer has more of a warm sound, whereas Alpine tends to be a little more airy. All of these headunits are excellent though. It really would come down to owning more than one and seeing which one you liked more. A lot more goes into which headunit to run besides price. Aesthetics, functionality, SQ, accessory compatibility (i.e. iPods), warranty, etc.
