Seems like it would be better, say, with a 24 channel setup, to have three ADAT cards (like the $19.99 EWS88D i recently won) and then run lightpipe to a cheap D/A like http://www.aphex.com/141.htm or even better to an ADAT->AES/EBU ( http://www.aphex.com/144.htm ) and then run AES/EBU to small powered monitors.
or hunt an old rme digi or hdsp 9652 on ebay, they have 3 adat i/o (plus spdif), good for up to 26 speaker feeds, if you want to go there.
but before you spend several kilobucks on that many speakers: most of the content out there is first-order, which will actually sound worse over that many speakers than, say, a dodecahedron or (as fons suggested), a cube or bi-rectangle.
more power to you if you build a HOA system at home, but unless more people (i.e. other than yours truly and maybe a handful of mad scientists at orange labs) get out and do actual HOA recordings, you'd better be into contemporary electro-acoustic, big time :-D
