Default 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.

Default 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.

Hi all,

Couldn't we start changing the SPDIF interface to few volts into 50 ohm, using BNC ?

Just a dream :-)

Default I have no problem with 50 ohms....

It is closer to the 30-35 ohms that RCAs are.

But why a couple volts? More EMI problems.

Default Supplier

I think I got it from Electrosonic. It is an Amphenol Part 31-10-75. Go to the amphenol web site for details.

You can also get it from Newark, Part no 90F8488, price 10,10U$

Bye...

Algar,
it would be more informative if you posted a picture of the 50 ohms for comparison. I can see no difference between what you have posted and the 50 ohms I have.

The 50 ohm ones have about 2 mm or so of Teflon around the part of the center pin that protrudes upward.
