I still think that the D1 with AD743 on 2>1 adapter and LME6655 makes the D1 amp equal to its DAC. There are a number of other opamps that also sound very good. The updated opamps that come standard are much better than the original offerings of the D1.
Keep in mind that the recommendations that are put forth on the forum are personal preferences only. It doesn't mean that there is one "best" combination that will fit everyones individual tastes.
We sometimes overlook that point as we attempt to describe the sound of various opamp combinations. There are, perhaps, at least a half dozen that are *very* difficult, if not impossible to tell apart in blind listening tests.
