Try different coaxial cable too. Sometimes male RCA connector does not mate well with female RCA connector.
Using CD player with outboard DAC
I have a CD player (Lexicon RT-20) and an outboard AC (Wyred4Sound DAC2). I am using the Remedy Reclocker as well (works well with the Sonos). The Sonos workswell, though I have not been able to get the CD player working. I am using JPS Ultraconductor 2 digital coaxial from the Lexicon S/PDIF to the ReClocker (I've tried direct to the DAC as well). I have an S/PDIF connecting from the ReClocker to the DAC2. Not been able to get any signal... am I missing something? Is the JPS unidirectional with digital?
