hi all,any help would be great....i have a marantz network player connected to my primare amp with phono cables,i bought a new bel canto dac and wanted to test it with the marantz.i connected a digital spdif optical(the only dig output) to my bel canto and because there are no more phono inputs i tried xlr.i bought a pair from amazon,not the dearest but also not the cheapest,and connected the bel canto with xlrs to my primare and i am getting no sound from the amp.i plugged in a pair of headphone and i am getting sound out so the optical is working.i checked that the button on the back of the bel canto is in the fixed position and i tested the xlr cable for continuity.anyone see anything i'm missing.its the first time i have used xlr so i am at a loss.cheers.
