In a month or so I will be getting my first HT system. I live in a 2nd floor apartment and my living room is roughly 12 x 12. Just in case it matters, here's what I'm planning on getting: http://www.psbspeakers.com/ Image 4Ts, Image 1Bs, Image 8C, Subsonic 6i with... http://www.bestbuy.com/site/olspage....3&type=product Yamaha HTR-5590 So, I know the system I want, but what are some specific products I'll need? What are the little things that people always forget or are needed to perfect the system? Here's the things I've found looking through the FAQ. 01. A Calibration Disk - I'm leaning towards Avia because I'm a newcomer 02. A SPL Meter... brand/model suggestions? 03. Banana Plugs - How many? What brand? 04. Speaker Wire - How much? What brand? What gauge? 05. Surge Protector - brand/model suggestions? 06. Component Cable for Receiver to TV - brand/model suggestions? 07. Xbox High Def Pack or Advance AV Pack. This one's weird. I'm not crazy, right? This IS the same product, isn't it? http://www.xbox.com/en-US/hardware/advancedavpack.htm http://www.xbox.com/en-US/hardware/h...tionavpack.htm My PS2 and Gamecube already have S-Video, so there's really no reason to buy component cables. So, opinions and suggestions are obviously wanted Also, did I miss anything? Thanks in advance everyone!
