Denonlink is an audio-only interconnect, but it is the only connection between my 3806 receiver and my 3910 player that I need (transmits all available formats from the 3910, including DVD-A and SACD). A Toslink i/c would not transmit SACD, only DVD-V and DVD-A. The 3910 also has Firewire, but I don't have any compatible equipment to take advantage of that interface (which would also theoretically work over that distance). If I moved the player next to the PJ, I could then theoretically use a 50 ft. shielded Cat 5 cable as the connector between the two instead of a 50 ft HDMI connector between the player and the PJ, then revert to a shorter HDMI cable that I already knw works fine. I just need to verify that the Denonlink signal won't degrade over that distance (seems very unlikely given the much smaller BW required for audio only signals), which I plan to do in the next few days with a 75 foot shielded Cat 5 cable. The downside would be that the player and receiver would now be on opposite sides of the room, but an RF remote could help with that problem. The DVIGear cable uses 22 gauge wire (the BJC cable is 24), so that might make enough of a difference. However, if the repeater works, I will have less total invested in the BJC cable AND the repeater than the cost of the DVIGear cable alone, so I am crossing my fingers. The repeater should be here by Wednesday-I'll post my results.
