Digital Interconnects - Which one is the BEST ??!!


i am not initially wanting to hear a brand name but more a TYPE of connection.

is Optical better than Coaxial ?  Is USB better than BNC ?   What IS BNC anyways?!     I read somewhere that a COAX input that utilizes any old RCA cable is much worse than a dedicated COAX cable - that was news to me!

After i learn these things, i will look for a good brand, but if there is a TYPE that outperforms other TYPEs i want to begin with that...

thank you for your comments


I have only used RCA and went from a 30 year old Audioquest RCA to the Audioquest Carbon and was a very significant and instant improvement across the board.  I later got a good deal on a Cardas Clear RCA and really didn't notice much difference so that proved the great value of the AQ Carbon.  



”disambiguate”… Good one!


I don’t think you can separate bad implementations and formats. I think great designs / materials typically trumps the format. There are so many variables you just can’t point unambiguously point to a “better” connector. I would choose a great manufacturer in the category. 

        The answer is somewhat VERY SIMPLE: USB-2.0

Why! Most of the VERY top streamers I.e. (most expensive) come with just USB & Ethernet only connections. As does my Arender.

Example:  Aurender N30S4 $24,500.00 same with some other HI END brands $35K an UP.
