Hi Hal,
In the case of an integrated amp (or a power amp), if the design is fully balanced there usually will be statements in the manual and/or marked on the rear panel cautioning against connecting the negative speaker-level output terminals to any kind of ground point. Since in the case of a fully balanced amp that terminal provides a full amplitude signal, having opposite polarity relative to the signal on the positive output terminal, which of course should not be provided with a path that would result in its being shorted to the amp's circuit ground. And I see no such indication in the manual or in rear panel photos of the M6si.
That same caution, btw, would apply in the case of an amp whose outputs are internally bridged, as well as in the case of some older class D amps whose + and - outputs are offset from ground by a substantial DC voltage. So while the absence of such a statement is usually a pretty good indication that the amp is not fully balanced, the presence of such a statement does not necessarily indicate that the amp is fully balanced.
Also, as Ralph indicated above I would expect that the manufacturer's description of a fully balanced amp would usually proclaim that fact proudly and prominently.
Best regards,
