Well, coming to this late. Having read through this chain, or much of it, I'm left with a few inescapable conclusions: 1.) Amirm has been bizarrely aggressive, especially for a staff member who designates himself CFO, or Chief Fun Officer. There's fun, and then there's a peevish rant intended to give grief and express indignation . 2.) The Ygg costs $1k more than the RME. It'd be really bizarre if it didn't sound better.
The review from the musicians didn't give me pause until the line about the 8 year old son. I was a professional classical guitarist specializing in Bach, with a goddam golden virtuosic ear--and Amirm, you really shouldn't discount that so readily. It's true that audiophiles are absolutely up-to-the-task for identifying technical superiority, and often musicality--but while audiophiles without a musicians' background can and often do arrive at the same conclusion, I typically give more weight when musicians lend their opinion to musicality. Euphony and timbre is all musicians care about. That's their realm. That said, I've seen electrical engineer-audiophiles arrive at the same conclusions as me.
But . . . whatever my training, I can't imagine ever saying something like that as an 8 year old, unless I was Mozart. Or Bach. Or some other prodigy. Really? Because to me, the RME was lightyears ahead of where I was. Saying the RME sounds bad is just silly. Maybe in comparison to angels singing from the heavens--and maybe that's what the Ygg is. But I spend 4-10 hours/day listening to the RME--absolutely entranced by it, which is kind of distracting when I'm supposed to be working. That really does make it sound like the settings between the Ygg and RME were incomparable (though I'm perfectly willing to believe the Ygg sounds more musical).
I upgraded my 8 yr old Gungnir to an RME ADI-2 Dac. The RME was a world above it--as you'd expect. But above the Ygg? I'd actually have to hear it. Measurements will only get you so far. Try measuring paintings and see how far that gets you in the world of art. Measurements don't tell you about musicality. I can tell you Mike Moffat has a hell of an ear. But I'd also say, the RME has a good Equalizer, so it's pretty versatile, and can compensate for a lot of component / cable / tube shortfalls--but just frequency dynamics, not detail, imaging, and soundstage.
Oy, the internet.
