My other concern is the 15+ decible peak at around 19 kHz. It might be noticable after you use compensation circuitry because it will translate to 15 db above reference. I wouldn't worry about it too much, though.

Ryan, after checking out the response graph, it seems to be similar to the PSD2002, except more ragged. You could probably use identical compensation circuits (perhaps use a slightly smaller capacitor value) and still get decent results.
