MHDT Orchid TUBE ROLLING

Interested in hearing about tube rolling experiences with the Orchid and other MHDT dacs, namely, the specific comparative sonic characteristics of the various 396a, 5670 and other compatible tubes used in the output buffer. My only experience is with the WE396a that Linear Tube Audio installed in my new Orchid.

I have followed the recommendation made by 213cobra and have now rolled an Amperex made in Holland 6DJ8 into my Orchid.
I know my new tube has not burned in at all yet.But out of the box I am hearing what he has predicted. I'd describe the change as a more fully fleshed-out tone. I suppose what that means for me is that the already very good midrange of the Orchid has filled out even more. The female vocal I just listened to has more depth and sounds warmer and more beautiful.
Really looking forward to the sound improving as this tube burns in.@213cobra Thanks for the recommendation!

I should have mentioned that I'm using the 5670/6DJ8 tube socket adapter available on-line. It did not require any circuit modifications.
Also, now that I'm a couple of hours in, and listening to some orchestral music, the new tube continues to provide a more fully fleshed out timbre. I'd describe it as the note fundamentals are fuller and a tiny bit more realistic, though I don't know how that is possible.
