I'm pretty sure we've had this conversation before, but even the Mojo would beat out most $10k DAC on pure measurements because of Chord's approach. If you want to argue that the Mojo is a better DAC than the Rossini, that's a bridge you'll have to cross. The Dave isn't immune from the Objective 2 debate just because it costs $10k.
Hifi is about pleasing distortions, and all of these DAC's are so competent that tuning differences are the main reason why there's any deviation in output between DACs at all. In that regard, I do feel that Chord comes up short, and just isn't as engaging as Nagra or DCS's top products. If all you care about is a flat reproduction profile, there are far cheaper products that will get the job done.
MSB is extremely overpriced, and their dealer support network is kind of poor, that I agree with you completely.
