Pw link - toslink to wiim streamer coaxial to DAC.I'm a little confused by your question: What are you using as your music source? If the Wiim is after the PW Link, then it isn't getting 'corrected', unless I'm missing what you're going for.
How is this connected, all digitally?
Streaming via PW link. I want to have my sub corrected by ARC connected to my wiim.
