Spaz? I'm not spazzing, I've just wanted this technology for a long time and am dissapointed that it is completely antiwi-fi.
1) It's non-digital. I don't even know how they put that on the site. That's a powered-speaker/headphone jack. It probably even has power running over it.
2) Ripping all my cds in apple lossless does not change 1 important thing. When a song is stored digitally, it eventually has to be converted to analog for a speaker to use it. THAT is my concern. The airport express must be doing the converting, and I'm sorry, but that tiny little thing cannot have very good converters. Even if it is recieving an analog signal and directly outputting it to the jack, then you still have your computer doing the converting and at no point do you have the opportunity to create a better analog signal.
The point of the story is, whatever is going on with airport express, your analog signal is derived from a 16-bit 48kHz sample, AT BEST. For anyone who has studio grade loudspeakers or reference monitors, that's noticable. That's VERY noticable. It affects the clarity of your monitors enough to bother you alot if you are used to have a good A/D converter.
I just want to see this technology in a more proprietary format. I want to be able to do the A/D conversion myself, all I want airport express and airtunes to do is send the signal to my speakers. That's it. Right now it's doing conversions as well, and that's a bottleneck.
