I *must* recreate the magical
expereinces of hearing "On Land" on a toob setup for the first time..
a memory from 10 years ago that still makes me quiver at the thought
of it. That was some Audio Innovations rig, but I couldn't tell you
which.

Sorry to burst your bubble, but I don't think recreating such fond
memories isn't possible.
I remember hearing Faure's Requiem for the first time when I was
little. That was on my father's system, which consisted of Quad amps
and Quad ESL-57s at that time.
It brought tears to my eyes and moved me in a way I never knew was
possible. It never happened again after that.

No system, no matter what price class or quality, ever brought back
that same feeling that I had back then.

Audio Innovations: they had some very special gear at that time.
Could have been the "First" or "Second" amplifiers, both triode jobs
with either 2 x 2A3 PP per channel or 2 x 2 x 2A3 PP per channel.
Those things left me speechless when I heard them for the first time.
They were also among the first DHT triode amps to be available here on
the continent at that time AFAIK (1989?)
