Hi Sonicfox
I had a pair of Infinity Composition Overture 3 fronts and RS3 side surround speakers (Infinity CC3 center). I picked up a pair of M3Tis and was floored. I liked the little Axioms better than the Overture 3s! The Axioms are more accurate and much more pleasant to listen to. The Infinities always sounded like nice speakers. The Axiom, on occasion, sounded like live music. I sold all my Infinities. I had a pair of M50s in the front, but replaced them with a pair of Axiom built M60-like M665s. They're incredible. I have a pair of Axiom built M22 like side surrounds (M55s) and love them. For a center channel, I use the Axiom built Merak MC6H 2 x 6.5" drivers and a great 7" horn tweeter. Love that speaker!
I think once you get some M60s you will just shake your head in disbelief at how totally superior they are to your Infinity RS4s. JMO.
