I have been following this series with great interest And as it happens a wile back I acquitted a few D3a’s for another project.
Bas Horneman is working with them in his LD 91 and I see your positive reports. I am going to give them a go in my WE91’s. The question remains weather to load them with anode chokes or CCS.
This amp need a kick in the ass. It sounds good, very good, but they don’t have the dynamic drive of my puny little DRD 45’s on my 97db speakers.

I have more to say but out of time…John
