I understand Macm's opinion, and agree to a point. I don't completely understand the science behind it all, however I also don't understand Quantum Physics. I do know this, I used a high end Transparent digital coax cable and compared it to a mid-hi end optical cable, and in my system the optic cable sounded anemic. However my brother prefers the optic cable in his mid-fi (I say mid-fi by comparing it to my system) system. What does this leave us with? Only testing for yourself will tell. AudioQuest's web site has a VERY detailed paper on signal transferes, well worth reading. However I do not think it is prudent to spend hundreds of dollars on coax digital...$350 tops!!!! And you can spend even less on fiber...Under $100
Digital vs Optical for DVD player
While I have experimented with interconnects, speaker wires and power cords I woke up to the fact that the salesman sold the wife an optical cord for the audio portion from the DVD to the digital receiver. Out of ignorance on optical cables I look to esteemed posters here to advise as to whether a 75 ohm cable output would offer better transferance of signal than the an optical cable????
