One of the pages I went to noted that an earlier explanation on Denon's own website was that the Denon Link use LVDS to run 24bit 192khz stereo, or 24 bit 96khz multichannel down the shielded twisted pairs, and that each channel had the capacity of 1.something gbps. So it's probably not ethernet (and if it were some variant it would be very different due to the timing requirements of audio), and given the LVDS I can see that the short cable would be required, with very tightly controlled impedances. Still, another poster indicated they were able to use a regular patch cord on earlier Denon link, and others mention that it doesn't work on today's denon link devices. Would be interesting to rip one apart and check out the drivers. Still... $500 for a 1.5M piece of STP?
