What quest have you embarked on?

Yes to all accounts! Please check my system page. From Martin Logans, to Magnepan, to Orion Plus, to Altecs.

I only need less than a watt at the speaker input for my normal listening levels during the day, less during the night.

I kept the Orion Plus though because the speakers are truly special.

To answer your question, an amp quest and I'm done.

The room defines the speakers (small speakers in a large room or large speakers in a small room are not going to get the job done). So for my small room (15' x 11') I selected Reference 3A MM De Capo i speakers. Then I went on an amp quest to power them;

up first a solid state amp, Simaudio W-3 125 wpc
followed by a hybrid, Blue Circle BC6 25 wpc class A
followed by a tube push-pull, Melody 2A3 18 wpc mono blocks
and finally to a SET amp, Aria 2A3 5 wpc.

Aria, 2A3/vt-229(6SL7) SET, Italian designed - French made,

...and it sounds even better than it looks!
.

i have embarked on a quest to minimize the inaccuarcy of instrumental timbre, from the perspective of a rear hall location at a concert hall.

i believe this may be attained by attenuating the upper midrange lower treble, selecting suitable tube components, and employing a speaker such as the quad 57.

yep. I'm making astonishing strides at being OK with what I have, rather than being infatuated with what I believe I need.
