I'm on the virge of picking up a BFD, but have noticed that some stores carry different models. There's the DSP1124P and the FBQ2496. The FBQ looks more complex, and is about $100.00 more than the DSP. I believe its the DSP that most people are using for sub equalization in their HT, but I wanted to check before I buy, and see if the FBQ had any advantages, if it just adds stereo capability, or if it's just plain wrong for this application. Any insight here would be helpful. e: Also, has anyone found that certain RCA adapters work better or worse than others? Thanks!
