Looks like that model isn't out anymore. I found this one: JVC KD-DV5300 though. Seems to have the same limitation about DVD-Audio but does DVD-Video playback and they say it sports a 24bit decoder.
My Alpine deck has been replaced with the
DVA-9965 DVD/CD/MP3/WMA Tuner head unit. According to the Alpine website it has 24bit processing. It appears to be the direct decedent of my head unit with the exception that it appears to also play true DVD-Audio discs
.
"• Disc Playback Type: DVD /
DVD Audio / DVD Video / DVD-R / DVD-RW / DVD+R / DVD+RW / VCD / CD / CD-R / CD-RW"
Edit: Just noticed that they listed the retail price as $1,600.00... this has got to be a typo. I'm guessing that the deck probably lists for about $1,000.00 (or less) as mine was about $450.00 2 years ago. While they certainly added a number of features on the DVA-9965 compared to mine, there is still no way that it sells for $600.00 more than their touch screen models.
