Who said anything about 75 ohms?
I once put a $2000 Gore-Tex cable (with Type N connectors) on my my SPDIF setup. Fantastic bass. Top-end was smeared.
I also had the same cable with SMAs. Same effect. Think I gave them to a guy were I used to work, as that is where they came from, and he claimed to need them.
Yeah, that is what I should have been making all these years. $5000 SPDIF cables. Bet I could not have ordered them from Gore-Tex fast enough.

Yes.
It was for a $150K microwave network analyzer, and came with more data than you can imagine so that its error contribution could be factored in. It really was worth $2k, unlike the snake oil cables audiophiles buy.
So, therefore, at $5k for audiophiles, it would have been a bargain.

Give the guy a break, man.......
For a 50 ohm cable, it sounded much better than you would think. And the bass was really good.
But I have no explanation as to why exactly it sounded that way. Generic 50 ohm cables are all rotten. Usually the bass and top-end are messed up when you have mismatches.

Yeah !, Give Me A Break, Man.......
My question was about why Jocko's 50 ohm borrowed cable sounded good in the bass, but messy in the highs - now I understand that there was gross impedence mismatch, but still Jocko himself questions why the bass sounded good.
Jocko, is there a difference to using a 75 ohm or 50 ohm optimised system ?.
Eric.
Doh, did I miss that the discussion is about 75 ohm systems or something ?.fdegrove said:Hi,
Eric,
Wake up...the man's feeding you all the data, punch the number(s) in please.
Cheers,

50 vs. 75 ohm
Since I was developing a product for retail sale, it had to be 75 ohms. However........I bet if I made one just for me, and I made it 50 ohms on both ends, that Gore-Tex cable would be killer.
Matching interconnects for sonic properties is common pratice for audiophiles, although I think that is silly. Oh wait.....I said "audiophile". That explains it all.
Problem is, the some morons think that the same practice holds true for SPDIF. Anything that changes HF response is causing jitter.
