I've already given you the link for the Kenwood Excelon KDC-X993. It has the Wolfson 24 Bit DAC (some say it has better sound quality than the Burr-Brown DAC), it has built in bluetooth, Aux, and USB. It has 4 volt pre-outs...not the best, but not the worst either. It also has Dual Zone, and Digital Time Alignment. Lastly, if you go here:

You'll also have a 2 year warranty through
SonicElectronix. I know some people don't care for Sonic. I have never had an issue with them, and their ratings over at resellerratings.com are actually very good. The Kenwood X993 has it all over the Pioneer 710. Remember too that the Pioneers use the Pico fuse. I've not had any problems with mine, but there are MANY here who have.
