I agree with John. You need to get out there to someones house to listen to the Axiom line up. Bring beer.
The issue you are having with the 901 is that you have little to no base in them. For the classical high notes they may sound great but once you go with lower, base effect music you loose out on the effect. Same for the Lifestyle 25 (what cheese d**k came up with that marketing machine of a name). Once you get a good center and great sub your eyes will pop out and you will kick yourself for not making this move earlier.
You do need to take a look at your reciever and let us know what you have (model #) and we will steer you in the right direction if it is needed.
