paulgardner - When you say tuning of upstream components, what are you referring to? Things like tube rolling? Adding an EQ? Room treatment? Thx
Paul - yes but it depends. let me explain, but its getting outside of your OP question. I break it down between big rocks and smaller rocks. Bigger versus smaller expected changes.
For example you mention tube rolling.
I consider tube rolling a smaller rock. It’s a refinement, of what you already like. You're on the same road.
Now going from Solid State to Tubes, and Vice Versa - that is a bigger rock. That is a change in the road. Now IMO, one can (and I have and do) run B&W 800 series with Tubes and SS, it just depends on the size of the room and your listening style.
make sense?
