SPDIF to analog conversion and vice versa 2017-10-20 22:49:34 Trying to solve a long analog cable length problem. My subwoofer is in the front of my family room and the home theatre receiver in the back. Connecting those two are a 20-30 foot cable terminated by RCA jacks, all in the wall. Yes, there are lots of electrical noise problems to the point that it's unusable. It's two-conductor single-ended, looks like coax.I'm thinking about using analog->spdif and spdif->analog converters in order to use that long cable as a spdif transport. That seems to be the most robust solution given my predicament.Other options and their cons:- Run line-level --> Lots of electrical noise- Run speaker level --> Sound quality is terrible- Wireless transmitter kits --> Don't like latency problems, powering on/off problems, general flakiness, sound quality- Cannot run new cables through roomQuestions:- What good quality spdif/analog converters are out there? Throwing a/d and d/a conversion into the mix can't be good for sound quality, but seems less bad than the other options. Thinking about getting monoprice ones.- Are there better options for me?
