Audio-Magic Blackout Paint

Sounds kinda weird I know, but as I am a true believer in everything that Jerry does at Audio-Magic, I decided to give his tube paint a try. Apparently, it keeps EMI/RFI from getting into the tubes. It also prevents stray tube emissions from affecting any adjacent tubes. All I know is that it works! I painted the power supply tubes in my phono stage which consists of one ECL 82 power tube, one EZ80 rectifier, and one StR 85/10 regulator tube. The difference in tonality-richer and more dense midrange, was apparent right away. Because the paint is easily washed off with a moist cloth, I was able to hear back and forth what was going on. Sure enough, the naked tubes sounded threadbare and a bit coarse and grainy. I brushed up the tubes again, and re-listened. The dimensionality and focus came back. What I also heard was a "realness" to the music-like I had more of a connection to the performance.
The cost of this upgrade is very small in relation to the performance boost. Give it a try!
