Teddy, that is really how it goes!
Surprisingly, with certain inductor combination, I realised that TA seems to take more power than the gain stage! Did not measure it ever - just observed how it was taking voltage down by the current thru the inductors.
While gain stage by it's count, reapped more by the dedicated 0V runs than the TA.
Now, I am having each resistor and transistor separated by their own dedicated RC but VBE has been in my mind long time. Nice to see you did it. I have no doubts what so ever for your results.
This is (as Andy once said about the dedicated 0V runs) how the very best preamps are made. At least one way to make it.
Thanks for your effort and splendid photos, Teddy!
Must say I envy your space in 102. I gotta do it in a shoebox 62.

P.S. You need a lot more 0V runs from your gain stages!
Then you'll know. That is the enlightenment. A Super-NAC has to breathe freely!
One common 0V rail from a stage is like having a hyperventilation going on..
