Kenwood KDC-X7533. Disable the onboard amps via menu, looks plain as a preachers daughter, and it runs twin Burr Brown 24bit DAC's

Plus the price is right.
IMO, the best headunit depends on the user. The top end Pioneer, Alpine and Kenwood headunits are so close to each other sonically that i bet most of you couldnt pick which was which in a blind test. IMO, buy the one you like the usability of - spend $X on a headunit from the big three, and you'll get approximately equivalent performance.
This is my opinion of what you get for your money, from years of dealing with mid-high end car audio :
-
Alpine - Wins on CD transport quality and MP3 processing. Fails miserably on usability.
-
Pioneer - Wins on SQ processing ability and ease of use. Fails (mostly) on clean looks, except for the P80RS and P90RS which are both stunning.
-
Kenwood - Wins on DAC quality and clean looks. Fails on processing and featureset.
I've sold
Sony in the past and think that, for the money you pay, you get a load of features - its just a shame that one of those features wasnt 'lasting for more than a year on average'.
JVC, i'm the wrong person to ask about - as a store, we had a 35% failure rate with JVC when we had it, and the SQ is just plain meh.
Of the big boys, that only leaves
Panasonic, which i havent heard any horror stories on but havent heard any positive ones either, and they seem very bling focussed.
At the moment, i'm running a high end Kenwood, and love it. I've run Pioneer in the past, and liked that too. Alpine, i've run, probably wont again - the engineers were geniuses, but the UI design team were idiots - a blind, fingerless autistic Impressionist painter could come up with a better button layout than whichever tools Alpine hired to do the job.
