Take the store up on the in-home demo. That is the only way you will know for sure. I had to sign up for an in home demo at 1 local store and the salesman suggested picking it up on a Saturday. The store is closed Sun and Mon. Another option would be to bring your speakers to the store but the chances they have the same electronics and room configuration is pretty nil which again you should take them up on the offer.
Good Luck
