Are tubes psychological?

It could depend on where you put the tubes, and what you've ingested before you're using them. 😉

It’s a beautiful thing!

Have an Amp with six KT88s on top of each monoblock.Generally listen in the dark. Except for the tube glow. Gotta say they make the perfect light once your eyes adjust. Sounds pretty good as well.

Yeah, a good tube amp is something else.  It just pulls out the atmospheric, ambient, and most importantly, the 3D musical shape plus the multiple layers locked away in the music.  While my Pass Class A amps sound good, they don't get the natural flow that my Lamm bottle amps cook-up.  The music just comes out from such a black background; it's an immersive and thoroughly enjoyable experience!  Music is one of those things that rejuvenates the soul, so in that sense, maybe tubes do have a psychological healing or relaxing element to it...  

Like "I emit, therefore I am?"
