Small system with Devialet 250/Focal Diablo Utopias - worth upgrading to 800?

[Dr Tone]

Apart from being true dual mono and completely removing any stereo cross talk that could happen in a single unit, there is also the 384khz over-sampling that starts happening in dual mono mode.  More power might be the least important part of the change unless you have particularly difficult speakers to drive.

What exactly is this 348khz over sampling?  I have seen this figure mentioned before but only in general terms.  Do you have any further details of how this is implimented or what it actually means?

I don't know if there is specific literature. My take: each unit has the processing power to do DSP at 384khz if only doing a single channel per unit.

There would be no advantage to over sample and then immediately going back down to 192 for DSPing so I have to assume it stays 384 all the way through in the 400 and 800.

But I've been wrong before...
