Rives Audio is owned and operated by one of the long-time Audiogon "regulars", and I have always found his comments to be technically sound and helpful.
I recently purchased the "Rives Audio Test CD", which is used to test your room acoustics to see where there are peaks and valleys in the frequency response curve. There are 2 sets of frequency sweeps (each with 32 frequencies), and one of the sets of tones is specifically calibrated for use with the Radio Shack analog SPL meter. The test disk, with shipping, is about $20, and is an excellent tool for evaluating your room's acoustics.
I suggest you buy the Rives test CD (and the Radio Shack SPL meter, if you don't already own it), and evaluate your room. Then you can talk to Rives directly to determine if their PARC analog equalizer can improve the frequency response in your room, or whether you will need more sweeping changes.
