This may be a stupid question but are you using the SC6000 provided RCA cable for the digital output or did you buy a Digital audio cable (coaxial)
I was trying the cable with my FiiO DAC (Digital to Digital) and it is working without any issues even that in the manual is written that there are 2 RCA Audio Cables included in the package.
Should I purchase explicitly a cable for digital signals ? Will it be a benefit ?
At these short distances at home, there won’t be any difference.
I would use the real 75Ohm digital internconnect cables in a pro environment or if many (power)cables are next the them. I did exchange them (yellow is easier to find in the dark), but not to any real benefit IMO.
Thanks for your answer. For now I am using mainly the analog out but If I will switch to digital I will follow your advice. I am wondering why Denon did not include already digital (75Ohm) cable in the box. I assume that would do for analog audio as well. Of course to buy the digital cable will not be too expensive.
