MHDT Orchid or Lampizator Amber 3?

Used the Shuguang CV181 in my Modwright LS100 preamp, found it very good sounding. If you want a suggestion for another very good sounding (TME) new production tube you might try the  Sophia Electric 6SN7; I use that it the LS100 now. 

I have a couple of Sophia Electric 6SN7 tubes from my LS100. Has anyone asked Jiun about using those in the Orchid?

My Mullard 6DJ8 variant is still on the way to try out in my grannyring modded Orchid, but your experience with the   CV-181-Z is certainly intriguing. I can't imagine though leaving the dac uncovered, and I have no idea as to how I would go about enlarging the hole for the larger tube. Have you given any thought as to how you would  do that, and make a neat job of it? Would be nice if MHDT labs offered a lid with a larger tube opening, but I don't know if they would go for that.

Decent machine shop could do it, only needs it if using 6SN7 or CV-181.
