Why not a run high quality USB cable

There are active USB extension cables like that one that measures 32ft:

^^^^ That should make it easier for people who don't want to run a cable across the floor from computer "front end" to DAC in rack and people with big rooms. Nice price too!

Most active USB extensions dont work for audio streaming. I would recommend trying Opticis.

Steve,
Would it work with USB to Toslink Converter? My friend wants to run 30' of cheap IC from the sound card to receiver while his receiver has Toslink input. 30' of USB extension + converter + 3' glass Toslink is perhaps better?

Steve,
Does the repeater "screw up" the timing of the stream so that implementations that depend on "constant" USB rate for clock recovery don't work? If so, async USB may not be affected. The price is so cheap, I may just get one and try it with my QB-9.
