DACs: Airport Express vs waveterminal vs mini-dac

Hi Steve,
How do you upsample on iTunes using a Powerbook?

To upsample in iTunes on a Mac (running OSX 10.4.4), go to your applications folder, look in the Utilities subfolder, open up "Audio Midi Setup".

Under Audio Output: format, you can upsample to 96,000 Hz.

I only see up to 48,000hz on line out. i even tried digital out; no 96000. Any ideas why?

96kHz is only available on the newer Macs.

I think that the newer Macs have the Crystal CS84xx which is actually the same chip used in a lot of high end DACs.

I have compared using Airport Express and hooked it up to my Meitner DCC2. All files were Apple Lossless. And yes, the Meitner CDSD-DCC2 is still heads and shoulders above Apple-Airpot Express-DCC2. Not even close.

Having said that I love using playlists for "background listening" such as parties. dinners or when I am working on something so it does have its purposes. The question I have is there a major audio quality difference btwn the wirless solutions....somehow I doubt it...Airport, Sonateer's Bard Audio etc...I am sure Wavelength etc will be better than the wireless solutions but then it simply doesn't work for me as my files are in PC and external hard drive in a different room. My thinking is that if I want to really up the ante on sound quality while retaining the functionality, then either need another notebook + wavelength....or go get a sep hard disk based player such as those offered by Olive and then hook up to the DCC2 and use the latter's DAC.
