Yes, but it is yet undecided if changing gain from 0x80000 to 0x7FFFF will produce bit-correct output with correct phase. See this head-fi thread: http://www4.head-fi.org/forums/showthread.php?t=106249
Unfortunately I don't currently have audio HW capable of recording digital signals with sufficient quality to figure this out myself. If it is verified that the Squeezebox can give bit-correct output with phase both inverted and non-inverted, adding a phase-invert control would be of interest to the audiophile community...
