@fjrabon , I have come full circle after spending a little more time on F1 with the Grace. I bought an M900 myself and now think it sounds better than anything Schiit makes below a thousand dollars. It just sounds much more transparent (easier to pick out guitar amps and vocal effects) with much more variance in instrument and vocal tones depending on the recording being played.
The Schiit and DACport implementations of the same AK4490 chip just sounded way more colored when used as just DACs than the Grace too. It makes me really want to hear the new RME ADI-2 Pro converter that everyone is raving about how it performs superbly both objectively (highest AD SNR specs ever, DA SNR competitive with Yggy but below the Apogee Symphony) and subjectively (sounds much clearer and less colored than the Apogee and other pro stuff that measures better than it in Digital -> Analog). The RME headamp section is supposedly warm and way overpowered for dynamics and but not enough for the HE-6 though.
