Yes, circumstances. Like I said, it depends greatly on the size of the venue or bar. If youre letting a bunch of volume off the stage that the soundguy has no control over.... you arent doing him any favors. So unless the bar is small and the PA isnt very adequate it shouldnt be a large difference to the crowd. Certainly not enough impact for somebody 20 feet back at a bar to hear the smaller portion of bass that is coming from the cab and think to themselves that it sounds like a Class D.I have played several thousand gigs during my time as a working bassist(on pace to do 135 this year, in fact) - in settings from small bars to huge outdoor concerts... IME, a rock band with a loud drummer and backline to match most definitely can be heard from the stage - in addition to the PA... Now, this also depends on where a person stands - fairly close to the stage, they'll certainly be able to hear the backline a bit - whereas, further away it's probably all PA... None of that requires a person "playing too loud", as you inferred - it's just varying circumstances...
Thats the whole context of this thread. The talk of Class D making a difference or not. So I was simply pointing out that in many scenarios, from the perspective of the crowd, more of your sound is coming from the PA than your cab.
I like Class D...and I like my giant old school amps as well.
