for 3100$ i would go with the monitor series from paradigm...monitor 11v6(fronts).. cc390(center) and apd 390 (surround).Paradigm is known for this great performance line at an abordable price.
I auditioned the Paradigm Studio 60's which is upline from the monitor series. The Studio 100's were out of my price range. I was introduced to Axiom and was told that their M80's are very similar in sound to the Studio 100's. The M80's are also highly efficient. I was going for fronts and a sub but shopping in their Factory Outlet Store I saved 10% and then another 5% for buying 5 of more pieces.
So I am getting:
Pair of M80's
Pair of QS8 surrounds
VP-150 Center Channel
EP-350 Sub all for $2596 shipped from the Outlet Store
The EP 500 will bring you in just over $3000 for a complete system shipped and a 30 day trial period.
My system should be here some time next week. Can't wait!
Best of luck deciding. It's pretty tough!!!!!!!!!!!
