Just in case you were thinking that prices for cabling were fair and reasonable, I give you this:
“High quality” cables don’t make any sense in most modern home entertainment setups. As soon as your signal is digital, you’re dealing with packets - packets with checksums and resends and all of the techniques that let me send an email flawlessly to Australia on a whim, even over a crappy dialup connection.
Unless it’s an analog signal, or perhaps a crazy-long cable run, the quality of the cable should be almost entirely irrelevant.
