Hellboy Greg, if you are planning to use with your duo Chi-Chi I'd say you should definitely give it a try. For me the PAS has been both inspiring and unspectacular. I think the overall sound and coverageare fantastic. The only time I heard it used in a hall was with a OMB and I missed the various dynamics of up and down volume and things like that - but that could have been the musician himself; he wasn't very impressive himself.
Give it a try.
