I am new to this site and new to the home theater components, over the past year I have been building a home theater and sound system in my house. I purchased the boston acoustic mcs130 system and upgraded the rear speakers from the smaller speakers to the lcr 130 large speakers and then added two more to make it 7.1. I run this off of an onkyo 706 with monster cables and what not, and I have to say I have been very happy with the system for movies and music. Recently my wife and I were in best buy and I listen to these floor standing klipsch speakers and I was taken back with the sound. So I am thinking of changing out 2 of the speakers and adding 2 floor standing ones, but this is where I am stuck. Ive been looking at the klipsch rf-52, boston acoustic cs226, and the paradigm phantoms. I am wondering if I change the company will it mess the sound of the system up, and which one is better for the money. I want to stay under 1000 for the pair. Please help. Or does any one have better speaker ideas, I like Dave Matthews type music and action movies on this system. Thanks for any help.
