Review on 🔊 J-Tech Digital Optical/Coaxial Audio Extender/Converter over Cat5e/6 Cable up to 990' for Dolby Digital, DTS 5.1, DTS-HD, PCM [JTECH-AET1000] by Sean Burnett

I used this to extend the digital output from my Sonos Port living room to my sunroom. through a coax wall outlet, through my basement, through my attic, through my garage, and then through a drilled hole in the eaves through 100 feet of Cat6 cable (and about 8 feet of coax to the wall outlet). That works great. Only the transmitter is powered while the receiver is cable powered and has a power LED indicator. I also tested it without using it and it only worked over regular 100ft coax, but it's WAY out of spec and I decided to just use balanced audio and get it right. It's been great so far and if I decide to move something at some point I'll have a nice Cat 6 run that I could use for something else.
