I'm thinking of selling my current speaker setup and getting the new Pinnacle Quantum satellites and the Subsonic sub. I'm currently using DefTech Pro Tower 400s, and Cambridge Soundworks Center channel plus with Surround 5.1's. Has anyone heard these speakers? I've read some good reviews. My wife hates the imposing ProTowers, and I thought it would be a good excuse to buy something new. Would I notice any difference from my current setup? It's all driven by an Onkyo TX DS-777.
