OP,
Remember, new ones need break-in. Brent Jesse told me: Leave on for around 60 hours (no signal required), then compare.
Are you saying listen to spares of the same brand? I would not bother unless I suspected a problem.
If you mean, try different brands, it is fun to satisfy curiosity and learn. I blew one, bought matched pair new 6SN7's for my Cayin, hated them.
Tried some old tubes I had in a drawer (I've got a lot of NOS and used), loved em. Brent Jesse let me return and exchange for new matched pairs of those, and they cost less, gave me a refund for the difference, no restocking charge.
It's not just the power tubes that can make very audible differences.
You can confirm your current choice sounds best, or find something else you might prefer.
Cost: nothing but time (after you buy a toy tester).
