So, I'm considering upgrading my speakers. I currently have the original Energy Take5 satellite speaker system, and am wondering if there's anything out there that would be a significant upgrade, that I can get for $800 or less, including tax, (or shipping if out of state, CA) or tax+shipping if mail order in state. I just bought an SVS 2039pci, so the sub is taken care of. I've considered the AR15's and the AR2C center... but am just not sure. I'd like to consider something I know a bit more about, or can at least audition.
