@adasdad , I’m surprised no one has mentioned my lowly Gryphon Diablo 300 DAC module before you did! You are right it is a bit of a mismatch. Cost wise the MU1 is only a little more expensive than my DAC module (although the DAC doesn’t have a big chassis so…) but that’s not saying anything really.
Not sure if there is anything to it but I’ve heard many say “It’s not the chip, but how it’s implemented”. That said I’m very familiar with the DAC’s strengths and weaknesses, and I’m sort of tied to it’s character, and the fact that I don’t need any extra cables or boxes. It does have a very slight hard edge in the upper midrange, but it’s offset by a dense and rich tone everywhere else (which I like) so it’s not really noticeable. Unless you crank it up, then it sounds hard/shouty, but I don’t listen loud.
In my experience, I’ve found that lesser components keep on sounding better and better if you keep feeding it with better upstream components - I’ve not found that lesser components hit a ceiling when fed by a component of a certain level or higher. Of course a world class DAC would sound better than my Diablo DAC module, but I’m fairly certain an MU1 class streamer/server would sound better with my DAC than a lesser class streamer/server. I’ve heard a school of thought that at beyond a certain level of streamer/server, the DAC stops mattering as much, and vice versa - at a certain level of DAC and beyond the streamer stops mattering as much.
Interestingly, Innuos seems to have launched and demonstrated it’s uber expensive Statement Next Gen (costs almost 2X the MU1) in Munich last year connected to a Gryphon Diablo 300 with its DAC module! At least it appears that is the case from the YT video. There is no DAC visible and just the Gryphon and an Isotek conditioner.
