Usb dac

I’m looking at the following USB DACs and was wondering if anyone had an opinion or any experience with any of them.

High Resolution Technologies Music Streamer
Cambridge Audio DACMagic
Musical Fidelity V-DAC

Although not technically a USB DAC, I was also considering the Logitech Squeezebox Touch. I have many high res music files on my laptop and would like to play them back on my stereo as opposed to headphones. I’m leaning toward the new crop of HRT Music Streamers with 24/96 support and asynchronous data transfer.

Any wisdom or insight is greatly appreciated. Thank you.
