User Experiences on Sophia Electric Aqua III 274B Rectifier Tubes

Here are my thoughts about the Sophia Electric 274B Aqua III

What can I say? This tube is fantastic and brings back the soul of music in my setup! I can hardly believe that it has such a big influence on the sound, really incredible. The tube replaces an EML 5U4G mesh, which sounds nice and airy and transparent, but lacks substance, power and timbre. My system therefore tended to sound thin, somewhat anemic and somehow cold, as if the soul of the music had been lost.

Thank you again for your advice, your tube is also a perfect technical fit (no arcing).

As an experienced tube roller, I can say that it is the best tube upgrade, and I didn't think it would be the rectifier 😉.
