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

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. 

I’m same way I care less about ohm’s just if it sounds good. Why would AZ prefer the absolute over the mc2. I’ve heard nothing but good things about mc2. Mc2 is only cable I considered or knew about before this post.

Sorry, can’t answer that unless they were just catering to your concerns about the 75 Ohm issue.  Frankly, if AZ designed a 110 Ohm cable for an AES/EBU connection and stapled RCAs on it where they’re not true 75 Ohm I’m a bit miffed and disappointed at that (I actually emailed them on this but never heard back), but again I’ll take a great sounding 55 Ohm cable over an inferior 75 Ohm cable any day and I’m thrilled despite what the numbers may say.  Like I said, my experience completely jibes with what I read in the consistently glowing reviews, so that’s pretty solid evidence IMHO.  Numbers are important, but they aren’t everything or we’d be able to assemble our systems from a spec sheet, right?
