If you have been searching for audio nirvana, you can stop right here. The Amperex 12AU7 Long Plate is, without question, the smoothest vacuum tube I have ever had the pleasure of hosting in my gear. It delivers that signature “liquid” tube sound that enthusiasts crave, often described as being as smooth as a baby’s skin, yet it never sacrifices technical refinement or micro-detail.
What sets this tube apart from its peers is its incredible tonal balance. Many tubes attempt to provide deep low-end extension but end up creating an overpowering mid-bass hump that can make female vocals sound unnaturally chesty or “bass-heavy.” This Amperex avoids that pitfall entirely, maintaining a clean, sweet high-frequency response that is characteristic of the brand’s vintage pedigree.
The only downside? These are becoming nearly extinct. They are increasingly rare and, predictably, quite expensive. However, if you manage to track one down, it might very well be the last stop on your tube-rolling journey. While the thrill of the hunt keeps me moving to the next pair, for most listeners, this is the endgame.
Final Verdict: A legendary, highly recommended performer that balances lush smoothness with high-fidelity clarity. If you find one, buy it immediately.
My tube rolling stopped here.
Update: well not quite, but I did keep these in for a few months straight and that’s saying something. Very enjoyable, until I set “brand obsession” aside and really gave the Sylvania JHS 5814 Gray Plates a chance.
