Could anyone explain - I have a CDP with AES/EBU digital out only and a DAC with RCA digital in. Can I use a XLR-RCA digital cable? It would be 110 to 75 Ohm as far as I understand. I have heard that Charles Hansen from Ayre among others (allegedly)said that I will not have any audible effect. Any experience or thoughts? Who can make such a cable in London? Thanx.
