Digital or Analog cables from Pre-Amp to Amp.

You want analog connectors. It is not as much a matter of the termination, as Bignerd mentioned, but of the resistance of the cable (if you are comparing coaxial digital to what you call "analog" RCA). Digital cables are usually designed around 75ohm resistance or less. I believe analog are typically around 100ohms. You could, in fact, use two digital coaxial cables if you were so inclined, since the terminations are identical and either one will work (you can also use an "analog" interconnect as a digital coaxial cable and it would work fine though may not perform optimally). What the difference in resistance actually means in terms of audio perforance...well, sorry, can't help you there...dunno as they'll both work in either application. Never gone through the trouble of actually comparing them. Someone with more smarts than me can splain that further, but the main differences are in the resistance, as I understand it.

Thanks for that clarification Robert! When it comes to electrical info, my synapses are not firing on all cylinders...or, er,...my elevator doesn't quite get to the top floor...you get what I mean!

So, out of curiosity, when you do mis-match the impedance in those specific applications, what are the likely results?
