Tube Cage On or Off. Does it Make any Difference?

Hey guys. I have a Mystere ca11 tube preamp which I really like. It's paired with CODA 10.5r SS amp, Manley Chinook preamp, Rega Planar 25 turntable, Dynavector 10X5, and Totem Sttaf speakers. I enjoy taking the tube cage off in order to amuse myself by watching the illuminated tubes while spinning vinyl. The question I have is whether removal of the tube cage affects performance of the device or sound in any way. I've played albums both ways [cage on and off] but can't really discern any sonic differences but wondered about the scientific aspect of my decision. Your thoughts are appreciated. Cheers!

"tube cage needed for pets and kids”

And audiophiles who occasionally overdo the scotch thing.

Think of it as a bra. Appropriate at times.

My power amps sound better without cages. Don't know if it is a resonance, heat, or shielding thing. Most likely resonance.

Sometimes a tube cage is called a Faraday cage, but only by those that had college level physics. If the cage is metal and grounded to the chassis, it WILL act to block RFI from getting into the circuts, other than that, i see no reason why the sound should change.
