Hey all, A great deal came my way on 6 Pinnacle Quantum Speakers and the Subsonic subwoofer, so I decided to go for it before purchasing the receiver. When I buy the 7.1 receiver, I will eventually add a 7th surround speaker to the mix. I have an average sized den (around 1800 cu. feet) with lots of furniture. I plan to put the speakers on the wall above the furniture, and the subwoofer in the corner opposite the television near the couch. Any set up suggestions? Currently, I am considering 4 receivers in the $800 to $1100 price range. They are the: Harman Kardon AVR7200, Yamaha RX-V3300, Marantz SR7400, and the Pioneer Elite VSX-55txi. My DVD player is a Pioneer 563A DVD/SACD/DVD-A player, so obviously bass management is important to me. My television is a 46 inch Mitsubishi WT-46807 with separate HDTV tuner. If anyone has any experience with Pinnacle Quantum speakers and/or the receivers I am considering, please give me advice. If you have a different receiver with the Quantum in my price range, I would much appreciate it if you could tell me what the receiver is and how it fairs with the speakers. Also, could someone give me a recommendation as to what the best calibration method would be for my type of setup, whether it be a setup disc, a Sound Level Meter, the receiver MCACC, or another method. Thank you for any help you can provide me with my soon to be home theater setup.
