I may have missed the follow up posting - but what was the outcome of the breakfast meeting with Bob?

I'm curious regarding the technical quality of the MS600 digital out in relation to the 8xx/ID40 options. Certainly from the internal photos the two alternatives appear to share the same chip architecture.

I've noted that various contributors here have suggested that the ID40 is superior to the MS600. Conversely I've read an independent mainstream review (somewhere) that suggests that, via the digital output, the audio from these units is indistinguishable...

The MS600 casing would appear to have a lot of spare real estate for a highly regulated linear power supply.
