One uses unsigned sample data and the other uses signed. This means that in order for sounds digitized on the Mac to sound correct on the Amiga that each byte of the sound sample data must be exclusive or'ed with hex $80 or the sound will be garbled/staticy. Otherwise, Mac samples should sound Excellent on the Amiga (at 11.1 KHz). I am not sure if AMax II automatically makes the desired conversion, and frankly I am not sure if it is possible for AMax to do this at all. Thanks for the reports on AMaxx II.
