Wow, 2400 sources is an awful lot of mixing to do, no matter how well the mixing loop is optimized.  Furthermore, once you get above 30-60 sources (depending on content), the benefits of adding more and more sources to the soundfield start to diminish.

It's not too difficult to implement a management scheme that can pick the n most important sources (nearest, loudest, whatever your app needs) and only render those sources.  My experience has been that it's difficult to tell the difference in a practical application (except for the CPU time you recover :-) ).
