Well, it all depends upon how one should interpret the spec's they've posted now.
The speakers' DSP is 32-bit floating point.
And previously, the coax s/pdif feed was up to 24/96 - and whatever entered the speaker, both s/pdif and analog, would be bumped to 24/96 before being sent to the DSP for processing.
But now the spec's state 32-bit 32/44.1/48/88.2 -- and have omitted 96. Which is such a strange decision that I'm pretty convinced they've simply forgotten to add 96 on the official page. I was told of the 32-bit in a phone call, and am not certain that this is the case. I would suspect that it should be 24-bit 44.1/48/88.2/96, as it used to be.
The fact that 96 is mentioned in the service manual for the latest version seems to confirm this. But do we know for certain? An acquaintance has been told by his dealer that the newest version does not accept 96 and that an attempt to play that will result in distortion, and that's what got me started down this trail.
