According to the DA and Transport List, this used:
SONIC FRONTIERS SFD-2 2 x UltraAnalog D20400A – SM5803AP
Had it been a MkII, it would have had the PMD100 instead of the SM5803AP. Same parts as a Mark Levinson No. 30, PS Audio Ultralink. Of course the supporting circuitry, output stage, etc. is probably completely different, so just cuz it has the same chips in it may not mean much.
