@rvpiano Any reason why you didn't try the DH Labs Glass Master Toslink? Might have been an interesting comparison between house cables (vs. your DH Labs Silver Sonic coax cable).
Are there differing qualities of optical cable?
I currently have my Gungnir Multibit DAC connected by optical cable to my Oppo player which I use as a transport. I also have a Cardas coax cable connected to a different input. The optical sounds better. My question is, are there different qualities of optical cable you can use, or is one the same as the other?
