I've now connected the SB direct into the 561M, and same result. But it does seem that this is due to the SB bug rather than Meridian (Slim Devices are more likely to provide a fix than M, me thinks).

An odd benefit of the SB bug, is that the 96/24 gets converted to 48/24 and so plays OK (the 561M display shows 48 for both the 96/24 and 88.2/24 files).
