@overthemoon "My interpretation is detail without coloration."
That about sums it up in the fewest words. This is what the OP was about, initially.
After a few decades of messing with caps and cables, and too many different amplifiers and tubes - recently went back to following and learning from a few different amp designers and hardcore techs. Have been revisiting, learning, and understanding voltage/current and associated manual re-biasing of amps opts, or tubes, reconfiguring to full Class-A operation, and how this impacts sound too. Interesting and rewarding.
I’ve come to the conclusion I still prefer a type of sound and presentation about half way between the old era of golden sound and the new era of hi-fi sound. Finding the preamp and amp designers who strive to achieve something close to this type of sound has been an interesting journey in itself. Ears and preferences vary.

Thanks to all for the varied and interesting replies everyone, along with your own interpretations and examples! Its clear people enjoy hunting for the type of sound they prefer most and trying different components to help get there. Keep up the good work - as they say 👍
