So this is going to be a little bit of a rant as this is a huge pet peeve of mine.  Ever since I've been into electronics (AV stuff specifically) I've been a fan of just about the cheapest cables I can get.  I usually get my cables at Home Depot and the best advice I got a long time ago was to use lamp cord (you know the bulk stuff you can buy to rewire lamps and such).  I've argued this a lot with people, mostly with sales guys trying to sell me the expensive stuff.  There have been study after study (and even a $1 Million dollar bounty if you can prove the difference) that show that the human ear (or eyes) can not hear the difference these extremely high end cables give.

While this is a little hard to argue for analog sources, for digital the argument is totally ridiculous.  Recently a salesman at Best Buy tried to sell me a 3 foot $265 Monster HDMI cable.  I burst out laughing when he suggested it and tried to explain to him "if it's digital, then it's digital".  He just couldn't understand that if ones and zeros are flowing then ones and zeros are flowing - the fucking cable makes no difference whatsoever.  Then yesterday I find this great post on Engadget showing that not only can people not hear the difference between Monster cable and cheap cables they went one step further and used COAT HANGERS to connect the speakers!  And guess what, no one could hear the difference between the coat hangers and expensive Monster cable.  Hey, anyone want to buy some $100 coat hangers???

Next time you need cables get the cheapest ones you can find, especially if they are HDMI.  Don't ever let the sales guy talk you into the expensive stuff no matter how hard he pushes.  If you need HDMI cables here are the ones I have, I have about 5 of them and they all work great (oh and they are $4.99 each!).
