I need to get a few HDMI cables, and a ton of speaker cable. I need some flat cable to run, about 75' total (so 30 for one and 45 for the other) and then for my mains. I know monster makes a good flat cable, but is there anything else I should be aware of? Also, previously I had used tyhe monster XP for my mains. I liked the price and build quality, but again, anything else I should see? And lastly, is there a good online store I can get all of this from?
