Why are there so few BNC cables to choose from

And is there a big difference between them?

@curiousjim 

the above is what you said, so a number of us responded

i typed in 'bnc digital audio cable' into google and about 50 options popped up, many from higher end cable shops or brands like nordost, dh labs, moon audio, art audio - reality is, bnc cables are just terminated differently than ones with rca ends, it is really no big deal, any shop that is selling cables they assemble in house can put on a bnc termination

is there a big difference between them? i say yes, if one's system is resolving -- but just like any other cabling, some will say none of it matters much

me neither, they are readily available, and provide a proper 75 ohm termination
