I purchased this cable after learning that digital coax cable connections may produce higher quality sound than optical digital connections. My concern was that my system wiring is unavoidable near poorly shielded equipment which could degrade the coax cable signal. I left my existing optical connection intact and made the coax connection as well. Doing A-B comparisons was as easy as just selecting a different input source on my amplifier's remote. I've been amazed at the improvement this coax cable provided. Gone is the sense of shrillness in loud high violin notes. There's a much improved sense of presence with greatly enhanced spatial imaging of the various instruments. It was not a subtle improvement. I didn't tell my wife what I'd done and she spontaneously asked me an hour later, "did you do something with the stereo, it's never sounded this good". And, with no disc in the CD player, and the volume turned full up on my 100W/channel amplifier, not a trace of hum in either my regular speakers or in my subwoofer. I'm very pleased!
Superb build quality, good looking, top notch protection from interference, and of course the audio signal is as pure as it gets. I expect these cables to last as long or most likely longer than any others I’ve ever tried. Phenomenal price. In most(if not all) other brands anything even approaching this level of quality would be much more expensive.
The answer is, yes! Why you ask? I haven't a clue. I have several older coax cables and they worked, I think. My new DAC is a special design employing R2R/Multibit technology and is expensive as hell and why would you use old and worn digital cable with a new DAC you ask? You wouldn't use old oil in a new motor would you? Of course you wouldn't. Same here, new DAC, New Cable. Now that's out of the way, let me say this cable looks and feels very capable and is very reasonably priced and has great specs. 5 Stars
