"I'd suggest getting a pair of the Axiom surrounds to replace your Polk's and stick with 5.1."
I had that thought also and figured someone would suggest it. For some reason, it is psychologically distasteful to admit failure on the initial research and purchase. I have no use for a pair of surround speakers so I would have to conclude that I wasted the money spent on the Polk surrounds.
On the other hand "Upgrading to 6.1 to improve the sound" seems like a very attractive option :-) Plus it is only 1 speaker so it is half the cost....
I can't afford it this month anyway, so I'll mull it over for a while.
