I went ahead with the Acoustical Zen silver MC2. I think the silver will serve this setup well...
I just couldn’t get over how the nagra with the audio zen seemed a little murky ...
Murky presentation on a $5k streamer! It might actually be caused by the MC2—not Albert Einstein’s MC², but Acoustic Zen’s MC2. This digital coaxial cable, sold by The Cable Company, has an impedance of 110 ohms. I was dumbfounded—who on earth designs and manufactures a 110-ohm digital coaxial cable these days? Interestingly, this cable doesn’t appear on Acoustic Zen’s own website, but it does show up on The Cable Company’s site for $500, and yes, it’s clearly listed as 110 ohms, the same specs for aes/ebu.
There are several uninformed individuals here (no names mentioned) promoting this cable, and you might be one of the victims.
When you use a 110-ohm digital coaxial cable on a 75-ohm standard connector of sensitive, delicate audio gear, reflections can occur. This leads to a ‘murky’ presentation—meaning veiled sound, reduced transparency, or even congestion during complex passages.
If you still crave silver (plated), try the DH Labs D-750 digital coaxial cable—a true 75-ohm design—and see how it stacks up against Cardas. Both features gas-injection and extremely low dielectric constant that yields low signal loss. Personally, I enjoy the smoothness of Cardas, but DH Labs wins me over with its greater dynamics and punch, especially in the low end.
