laptop to DAC wireless ... what's the best way?

If audio only I like the Squeezebox Touch, but beware that USB connectivity is not officially supported and pretty much only DACs that adhere to the USB audio specification will work. In my main system I use a Mac Mini to get video and more flexibility, plus options for playback software, which absolutely makes a difference in sound quality.

The NAD Dac 1 looks interesting, especially given it's price point. Much cheaper than the similar Audioengine unit. Does anyone have any experience with it? The few user reviews I was able to find indicate some interference with standard wi-fi. The DAC itself supports hi-res formats, but is that true with the wireless?

Wireless is currently 44.1, except for SB Touch which does 96.

Even the Audioengine D2? Quote from their website:
"The D2 processes digital audio at any bit depth up to 24 bits and sample rates to 192KHz, then sends your music over-the-air at 24/96."
