They are trained musicians and have a gift/talent/training to hear quality sound. but there is high quality sound that comes from a strat, or a les paul. high quality sound comes from a klipsch or a Keff.

Your making a point that "how come musicians can enter a crowded room full of equipment and within a few minutes be in total agreement about which units have the best sound" I don’t agree, and in comparison to audio equipment I think a crowd of musicians picks out a group of the best equipments in the room. But, still yet they individually favor one piece or the other.

I don’t see how anyone could say there is one best amp. One best speaker. Everything has a different sound or tone, not to mention every person hears differently. There’s lots and lots of great equipment out there.

It's my speculation that the musicians are quickly satisfied because they are 'producing' music and the tone they want is exactly what they are producing at that time in the moment. It is what it is, and that's exactly what they want.

Audiophiles and reviewers are looking for what they think or perceive as a perfect reproduction of what the musician played. It's not possible. They cant do it. They were not there when it was produced.
There’s just no perfect reference to compare.

Would it be close if you set up different systems in a recording studio. Right in the same room people played and compared the reproduction to the production? Only if your 100% sure there is no degradation from the production to the reproduction considering: mics, cables, recording equipment.

Why don’t you hear of musicians spending $5000.00 a meter for a mic cable or a guitar cord?

All kidding aside, I've noticed that the "tone" is more player dependant than the equipment a lot of times. I mean if I play a Les Paul with active pickups like Zakk Wylde does I can get a sound that approxiated his through my Peavey amp, even though he plays through a JCM800 Marshall. But I can't if I'm using regular pickups. So the equipment has something to do with it. But on the other hand I've seen really good players pick a POS guitar and run through their equipment and they still sound just like they always do. So a lot of it has to do with personal technique I think.

Why do a lot of people like the sound of a LesP through a Marshall? Because a large majority of music has been recorded/played live through this equipment so that's what we equate with good sound. Now I think a strat through a Marshall sounds weak, but completely awesome through a Fender Twin. Whereas a LesP through a Twin doesn't ring right. Why, because most of the blues players I've ever equated with being good play the strat/twin combo. Not all, but most (exceptions like Albert King, Lonnie Mack, etc..)

And the get all---most active guitar players I know try to listen to as much live music as they can cuz that's where the action is!

Was that meaningless enough for ya'll.
