I was thinking of something similar today. Many M owners with HD621 processors benefit from apodised over-sampling of 44 & 48k audio up to 88 or 96k.

Some of this will be 24 bit audio, and some multi-channel. And we know that apodising is heavy on processing resource.

If speakers could accept 192k, that would presumably push the apodising burden up much higher, wherever it is performed.

Applying speaker levels, delays and crossovers is one thing, but I bet room correction and apodising of HD MC audio is very demanding. Maybe too demanding for current hardware?
