Setting gains without a load is fine BUT all amps when spec for rated output are ran off a load and at typically a 1k wave. Now sub amps are a while different animal nit worth discussing. Unless you have a resistor bank the load setting is not possible. I have done both ways, especially initially checking clipping point with scope. But none the less gains are so sensitive I find making a mark trivial as even the slightest increment more or less can be as big as 50+ watts depending on amp and source voltage. YMMV. Practice the kiss method people.

Just jacking w ya brotha in good fun. OCD kicks the shix out of me even when I sleep man!!! It can be a good thing though. We like shix done right!!!

On point, I have not used any of my tuning equip in at least a year so my ears are getting wiser. Just never had any luck setting a number and getting quality or effective sound.

You are a young fella. At 55 my ears might be wiser, but I'm deaf.
What is an aceptable volume level for must people around me, it is extremelly low for me, and viceversa.

Fluke 179. Expensive as shix. Worth every penny. It's a lifetime tool. Amazon is your friend.

Used Flukes in the Navy so agree with you there. Probably too pricey for a single audio upgrade though.
