Would it be correct to say though that the internal DAC may be better than the Metrum?
Therefore, digital source => Job would sound better than digital source => Metrum DAC => Job?
As such, it may be possible that a better DAC through the analog input would sound better, assuming that the AD/DA section of the Job is relatively transparent. After all, Goldmund equips its pre-amps with digital outputs for use with the Telos 360 etc amps so the DA section must be up to scratch, one would think.
