I agree with pretty much all of that. The next question is how can I compensate for it with an amp's EQ. I tend to either run everything flat, or cut the bass. sometimes I add treble. Unsurprisingly, that's usually what my guitar EQ looks like too. Obviously this is room and volume dependent, but what else can I look to do?
I pretty much run my amps flat. I may boost the bass signal or cut the treble by one digit as I like everything as flat as I can - similar to you. Much of what Mark does I tend to do as well. Other things I do is lift my cabinet up in level so that my knees are not getting blasted by the amplified signal. Like Mark I use an Xotic RC to pump the solo volumes up. On single channel amps with a preamp and master, I prefer to kick the master up and use the preamp to control the overall volume - sort of opposite of what the controls indicate. This way I avoid as much preamp distortion as I can while lessening the amount of distortion coming from the preamp volume control. On single channel one volume amps - really no issues.
This is what works for me.
Outside of that, turn down.
