IMO buying from Best Buy is pretty much the worst thing you can do ever. I usually buy my cables online at someplace like mycablemart.com or cabletrain.com or whatever has the best price. Considering the prices at Best Buy are anywhere from 5 times to 10 times more I haven't ever thought twice about it until now.
However, I am no expert on cables so I was hoping someone could enlighten me a little. Buying an HDMI cable here pretty soon, is there anything I should be concerned about? I've boughten optical audio cables several times over from places like these and have never had a problem, however I think HDMI might be a little different (i.e. more magical and mysterious) than the optical's. Any thoughts?
