300B or 2a3 SET Class A for Heretic Model A?

Wondering which one would be the perfect match/magical integrated? 100db is more than enough to drive almost everything.

Between these: Mastersound Compact 300B, Trafomatic Evolution Two, Robson Acoustic 300B Masterpiece, WE91E or even Luxman SQ-N150.

Thanks in advance!

I look forward to getting them built and comparing them. As stated above, I would be looking into a PP 2A3. Very curious about how tyt would sound. I use a DIY SE EL84 with my Cornwalls and it drives them with comparative ease. Now, I don’t play particularly loud, and I’m not a bass head, so others may not find that satisfying. Do really like EL84’s, I do :) Listening to a pair of UA-1’s now, and even in their poor state (just got them) they sound quite lovely.
