As others have said Aperion is worth a listen since you have 30 days to return with no cost to you. Do you have a preference with how you listen to music? IE. will you be using a subwoofer, or listening in a 'direct' mode with only the towers?
The reason I ask is if you prefer to listen in 'direct' mode with no sub, I would suggest trying the 6T's over the 5T's. If you plan on using a sub, then it may not matter quite as much. I don't know what your buying plan is, but you do not need to get everything at once, maybe start with 3.1 and add the surrounds later when you have funds again. Also, if you order the Aperion's, check their Open Box area under the product list first, or contact them. If you can find what you want to order as an open box it's 15% off, and I believe you still get 30 days to audition.
For full disclosure, I have the 6T's (and a 5C), and listen to music in 'pure direct' mode.
