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!

I have the Mystere CA-21 preamp and leave the tube cage off all the time for better ventilation and appearance. You can leave it on if you prefer for better protection. I am very impressed with Mystere's performance and build quality.
I have an Octave V70SE and I leave my cage off all the time. It (as I was told by the dealer) is for protection in case small children or pets touch the tubes while it is on. Looks a lot better without it and I don't have to take it off when I decide to roll tubes.
Thanks guys for your responses. I didn't think it would hurt anything to keep the tube cage off but wanted additional perspectives. Since I don't have children, the issue with protecting the tubes from wandering hands isn't relevant. Like Hiendmuse, I agree that the Mystere preamp build quality is quite extraordinary. I enjoy the sound and performance that I receive from my gear at this stage.
