The new Infiniti G35 unveiled at the New York auto show rocks your typical Bose sound package but with a hard drive music server, a first in automotive. While it's not terribly exciting for our camp of audio extremists, it's interesting to continue to see how even more high-end audio equipment going main stream. There isn't much about the hardware other than this interesting bit about the DAC:

According to Infiniti, the unit uses a 24-bit DAC built by Burr Brown, which recently was acquired by Texas Instruments.

Though I can't find it now, I remember some company selling a tube-based car stereo system. Mark Levinson is in Lexus, Linn in Aston Martin, B&O in Audi...most people have better systems in their cars than in their homes. Sigh. News here and check out Autoweek for more pics.
