Hi all,

I would be up for this as I have a 12 card SDS7 system. However, I can
forsee one major problem: analogue to digital conversion (assuming
sound files are going to be posted for comparison). I use a Mytek
8x192 which is reasonably hi end i.e. transparent but using 
converters that are either coloured (Apogee) or of lesser quality will
introduce artifacts that may mask any small but significant
differences in sound between modules. I am not being a gear snob but
in the transparent converters group Bob Katz includes: Weiss, Lavry,
Cranesong, Benchmark, dCS, Mytek and Prism. I would add iZ Radar,
UA2192, DAD AX24 (Digital Audio Denmark) and Lynx Aurora. The Metric
Halo ULN-2 is decent but probably not as transparent as the previously
mentioned makes.

Additionally the DAW used to encode the .WAV might play a part in
shaping the data (dithering algorithms differ significantly) and
therefore the sound. I'd be using Logic (not a recommendation, just my
current sequencer.
