Advice on a good Digital Coax Cable to run between my Transport and DAC?

I concurr with facten, my Jay's is connected to the dac with a Snake River Boomslang AES cable with better results than even I2s. 

I’d also recommend looking into a DAC upgrade. That’s a sweet transport. Needs a dac on the same level. 

This was a + to my setup.

@lanx0003 Despite the impedance rating, the Acoustic Zen MC2 is notably better than other digital cables I've tried such as XLO, Morrow, Harmonic Technologies.  Probably others as well. I'm using the cable between my Denon DCD-1700NE player and my Gustard dac. 

@sls883  Out of curiosity, I called the Cable Company to inquire about impedance standards, as these are universally followed by industrial manufacturers. There are no exceptions—for example, 75 ohms for S/PDIF and 110 ohms for AES/EBU. These standards are regulated by the IEC, which governs the manufacturing requirements for both audio components and their associated cabling and terminations.

A knowledgeable gentleman kindly informed me that the information posted on the website—specifically that the Acoustic Zen MC2 is a true 110-ohm cable—is a mistake. It should be stated a true 75 ohm instead.  He confirmed the impedance standards I mentioned earlier.  Again, no exception.

He also added that while cable impedance is standardized, the terminal connectors used for coaxial cables are not always a perfect 75-ohm design. Small variations can exist—for example, a connector might measure 74 ohms—which could cause minor high-frequency roll-off. However, he confirmed that the connectors used on the MC2 are indeed true 75-ohm designs.  This also clarifies the misinformation in the previous thread https://forum.audiogon.com/discussions/acoustic-zen-mc2-110-ohm
