Hm, interesting device... Much cheaper than empeg, but apparently taking shorcuts almost everywhere - e.g. their shock mounting consists of advice to 'put anything soft under the disk', and interfacing to car stereo is bound to amuse our audiophiles here.

Howerer, as the unit is quite usefull for tasks such as making your music available in the office, the huge price difference could make it quite a competition for empeg outside enthusiast market segment.
