I do not have tube amps but my pre and phono pre have tubes but I cannot see them. What I can see on everything are big blue meters and they do have a calming affect on me while listening. Yes I am addicted to blue meters...!
Are tubes psychological?
This just occurred to me this morning as I listened in my rather dark listening room with the soft glow of tubed amps on the floor in front of me between the speakers: How much of my enjoyment of tubes gear is due to the relaxed state the glow puts my mind in?
Thoughts?
