The Kenwood is a no-brainer. The affore-mentioned Burr Brown 24 bit DAC ALONE should make that a no brainer. It's also much better-looking in my oh-so-humble opinion. In the last year, I've owned 2 or 3 Pioneers, and 2 or 3 Kenwoods (different cars, and I'm in retail and deal with both daily). The Kenwood is hands down better. Also, look into Pioneer's RAPIDLY declining customer satisfaction numbers and their rapidly rising return and defective rates.
