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
