What is the best BNC Digital Cable under $4,000?

I have heard $250,000 systems  was scooped off the curb. If the data is identical at either side of the cable, there will be no sonic difference. Don’t waste your money unless it makes you feel happy!

It might help to travel to understand it ain’t perfect round.....in the extremes 
the view from Kansas might lead one to the wrong conclusion.....

@cleeds

What evidence, other than testimonial, has been offered to suggest digital cables can be sonically different (exempting noise rejection)?

Good question. All you have to do if listen to any digital cable first one direction, then the other. The 1s and 0s sound better one way.

@mzkmxcv. While I know I’m beating my head against a wall let me try...

first you have to believe that superior clocking can improve the performance of a digital system. If, as is the case in my system or any other dCS rig, adding an off board clock (or in turn a 10MHz Reference to that clock) can improve soundstaging and definition then does it not follow that improving the accuracy of transmission of the clock signals in between the different components is also audible? 

The same logic holds for other non reclocked transmission paths such as AES/EBU and redbook over 75ohm as the OPs case. Reclocked standards such as USB behave differently and I have limited experience in this use case.

If on the other hand you believe that all digital connections are indistinguishable from one another and that CD=perfect Sound forever, then we are wasting our time and you can happily believe that none of this stuff matters and hoard your precious pennies for whatever else you want.
