"Great product for listening to HD Audio."4.0 starson by Yves_FLAC
Pros: Performs flawlessly on HD audio.
Very good sound that is great when hooked up to an external DAC.
The server software - SqueezeCenter - is not perfect but already very good.
Cons: Memory (128 MB) too low ; you can't really plug a large portable drive to the Touch USB and listen. That is too much for the power spec of the Touch.
Doesn't support 24bits 192 kHz for playback.
Summary: I am using my SB Touch everyday, and I look forward to an upgraded version (SB Touch II) that would go over the limitations ; I would definitively trade it in.
