I would also like the ability to set the pre-fetch buffer size on the SoundBridge M1001, either in Kbytes or in seconds.
Presently, I have 2 SoundBridge M1001's, a Denon 4308ci, and my laptop.
All playing the same Internet radio station at the same time, there are many cases where my laptop and the Denon play perfectly (no gaps for re-buffering), whereas the SoundBridges gap and go silent for 5-10 second re-buffering periods quite often.
Since they are all pulling from the same station, and only the SoundBridges are gapping, I believe the problem is the buffer size is too small on the SoundBridges.
Or is it something else ...
