.Speaker Cables
Despite all the myths and engineering fallacies surrounding speaker cables, these cables are not as critical as many cable companies would have you believe. In fact, many of these cable companies are simply marketing Snake Oil in fancy packages, and selling them to you for outrageous prices. The truth of the matter is, standard 10 or 12 AWG Oxygen Free Multistranded Cable (OFMC) is fine for most applications except for maybe the extreme scenario of a particularly difficult Electrostatic Loudspeaker (ESL) system driven by tube amplifiers, or extremely long runs (greater than 50ft) connected to low impedance speakers (4 ohms or less). In these cases, speaker cables with lower DCR and inductance may be more optimal to achieve the fullest potential of the system....
If you consider that even most high end loudspeakers are internally wired with 14-16 AWG copper wire, and the terminations of most power amps / receivers and loudspeakers are soldered onto binding posts, then ask yourself, how could these "exotic" cables make such an audible difference?
What is important in speaker cables is how you terminate them. You want to ensure that you have the tightest connection of the cable to your amp and loudspeaker to minimize contact resistance. For that, I recommend either spades or banana plugs. Despite the fact that Spades generally have greater surface area contact than banana plugs, I have found that banana plugs usually make for a better connection to most commercial binding posts found on loudspeakers and amplifiers. Always remember to keep you speaker cable runs as short as possible and not to loop excessive cables as this may slightly increase cable inductance.
If you cannot avoid running speaker wires in parallel with power cords, and /or your system is prone to RFI ingress, shielded twisted pair speaker cables may also be a great option. Many manufacturers offer this option for only a small additional cost. I suggest reviewing the excellent article written by Dan Banquer title " Bulletproofing Your System from Interference " for tips in combating noisy environments.

For even HDTV reasonable deviations from nominal impedance will usually be found under the hood in these electronic units because it's really not that critical at 37Mhz video bandwidths with 2 and 3 meter cables-even RCA plugs eg. are not designed to be 75 ohm - probably more like 35 (compare to BNC or F conn)..IMHO
