Having said that, I am afraid you have infected me with the bug. Now I feel I need to build the speakers, too, in order to maximize value. Crossovers and what not scare me, but that is still a bit off as I am not even sure what the different types (numbers) mean. I am thinking about the SEOS kits from Erich, and I see a lot of people using them in builds, but I can't really find anything that talks about WHY they chose the set they did (what the numbers mean in terms of performance/sound type/etc).
The HT will be used mostly for movies, and I am trying to decide between the Marantz AV7005 (http://www.accessories4less.com/make-a-store/item/MARAV7005/Marantz-AV7005-Networking-AV-Preamp/Processor/1.html#!specifications) or the Denon AVR-3313CI (http://www.amazon.com/Denon-AVR-3313CI-Networking-Receiver-Capacity/dp/B00829USKS) if it ends up making a difference on the advice you give for the speakers.
I would like to have at least five channels, but I could settle for LCR for now if I have to for quality. I think I have about $1,000 left to spend, perhaps a bit more (haven't factored in all the shipping and taxes yet, so attempting to conservatively estimate).
Could someone be so kind as to enlighten me on what the differences are, which sets might work well, or just anything to help me sift through all of this? If you would prefer to link me to things instead of explaining, I am ok with that, just need to figure out which direction I am headed so I can move closer to the buy/build!
