This is an old forum, but I stumbled on it decided to try a brand new model of the Moray James digital coax. I compared it to the Kimber Illuminati and the latest iteration of the Harmonic Techonolgies Platinum XLR digital cable. The associated equipment was a CEC transport and John Wright modified Bidat.
My first reaction was, WOW! The level of detail and musicality were amazing. I was hearing musical elements for the first time in recordings I'd been listening to for nearly 20 years. Anybody who says digital cables are all created equal should come and listen to my system as I swap these cables. If you hear a difference between speakers, you'll hear a difference between cables. Taste certainly varies, but for me, the Moray James reproduced everything more realistically and more musically. It provides all of the high definition I like without adding glare and harshness. One warning though: you must break in this cable for about 20 hours. More subtle changes can be noticed for another 30 or so. This is the best digital cable I've heard in my system.
