Suggestions for Giant Killer rca coax digital cable under $500 used

This is a digital signal so don't worry about silver in the mix.

I think @carlsbad2 might be onto something here.  When I substituted the MC2 for my budget but decent Apogee Wyde Eye the thought of it being silver never even entered my thoughts as the significant improvements across the board were what completely dominated.  If anything the sound just became more balanced and natural along with all the other awesomeness.  If you buy one used, and they do come up from time to time (that’s how I bought mine), you can try one for little risk that I think would be well worth trying.  Just my thoughts/experience FWIW.

Nordost Silver Shadow… even the NOS original..which @buff ( a dealer here on Agon ) may have…

Try a Audioquest Carbon. Fairly inexpensive and a great bang for the buck. Also, very well represented, so pretty easy to source.

I called Acoustic Zen they said The mc2 in rca is about 55 ohm’s and recommended the AZ Absolute, true 75 ohm rca. I’m not very knowledgeable with digital,

I know my JPS superconductors 2’s are true 75ohm but have no idea how that equates to sound quality vs the AZ mc2’s 55 ohm. The JPS are old I’ve had them forever maybe 20 years and have no clue how they have stood up with the test of time.

Is lower the ohm make a cable sound lean. 

I can just tell you what I heard, and I’m so happy with the results I care not about what Ohm my cable runs at as my ears are the final arbiter, and the reviews profoundly echo my findings.  Like I said, buy used and you can try it yourself with little/no risk, but I know my MC2 ain’t going anywhere anytime soon.
