We just recieved our first shipment of the Audioengine W1-a Wireless Audio adapter.  It has a 100′ range, and boardcasts very high quality 2 channel stereo.  It will link between any digital source  with a receiver, preamp, or powered speakers with clean high grade audio broadcast.  Trust me, we did an acid test with it using a Shanling CDT-300 Limited as a source and a Burmeister demo CD  with a 30′ run to the speakers.  It sounded great with no loss of staging or depth of the source material.  Admittedly the run could have been longer, but with the wide bandwidth and spread spectrum tech I doubt that it would have made much difference.This thing is a steal for 149.95.
