He is absolutely right. We all want to imitate the sound of the records.
I've seen all the great bands in the last 40 years. From ACDC (10 x) to ZZ Top. Among them also Rush, Santana, U2, Queen, Jeff Beck, Stevie Ray Vaughan*, David Bowie , Pink Floyd, Aeromsith, Rammstein, Metallica, Genesis, B.B. King, Huey Lewis, Eric Clapton, Toto, Bon Jovi, Dokken, Night Ranger....... and hundreds more.
I can't even list them all. But I have NEVER heard an amp in the room sound.
What I heard was either a great or not so great overall sound.
And it is a fact that the live guitar sound was not as nice as on the albums.
Except *
This was a great concert in the Amphi Theater at the Lorelei rock above the river Rhine.
The worst concert was in the early 80s. Van Halen. The whole band was on drugs or drunk or both. I was standing pretty close to the edge of the stage and the performance AND the sound was atrocious. Especially Eddie's guitar sound.
The best sound was AC/DC and PINK FLOYD.
The quality of the sound was and is dependent on the PA system and the FOH technician.
If you have a great "amp in the room sound" on stage, it's only until the drummer , the second guitarist and the bassist starts with his two SVT stacks. Then the nice AMP in the room sound is gone.
I have been playing with In Ear for quite some time. Actually all the bands I know here use In Ear. I just built a rack last week with a Midas M32 and three Midas DP48. In this rack also sits my AXE FX III.
And it makes no difference if we play in a club or on a big open air stage. The Sound is always the same and I save my hearing. After more than 3000 gigs I have to realize that I already have tinnitus. I do not want it to get worse.
At home I play with my studio monitors (PSI AUDIO A21). An incredible sound. I can absolutely recommend.
Amp in the room? I don't care.
