I know you (and likely others) won't believe this, perhaps only the SELECT II owners will at this point, but the SELECT II is such a breakthrough in digital, that it really changes the way you see a system.
Before, people got whatever digital "du jour", and then worked their system around it. DAC too harsh? Tame it with a nicely colored preamp. Or cables. Or bass traps. Or they just didn't care enough about digital and focused in their analog.
With the SELECT II, you don't need to. What you'll get out of the outputs is as close to the original recording as currently possible. So, just add any neutral enough amps, and you're all set. A suitably resolving speaker must also be part of this, of course...
MSB was never the DAC "du jour", it still isn't, and doesn't want to be either.
The jury is still out there for the MSB Reference, but that promises to be the answer for a lot of folks' prayers, for a more reasonably priced SELECT II. So, couple that with the now mythical, hopefully still forthcoming, cheaper darTZeel monoblocks, and you have a killer system
