Well, I guess that rules out the Klipsch. No point in getting a 5.1 system if I won't have 5.1 sound. (Too bad too cause they look pretty sweet)
So, that leaves the Z-560 and Z-5300 again. I just can't justify spending over $200 absolute maximum for new speakers when I could upgrade other things with the money instead.
Hopefully in the next few days I'll get around to seeing if Best Buy happens to have both to test them out. Until then, any input between the two would be greatly appreciated!
