User Experiences on Sophia Electric 12AX7 Tubes

I am using them in my SunValley SV-EQ1616D phono stage. The SunValley has a very vivid and energetic sound and can very easily get into the realm of sounding too bright for my tastes. After reading some reviews on your site, I thought I would give your tubes a spin. I was very pleasantly surprised. They somehow manage to capture the best qualities of some of my favorite European tubes. They have a sweet and musical quality to them, but are still warm and full-bodied. They capture all of the wonderful and nuanced little details and still have such a wonderful and natural weight to them. Sounds stage is also enormous! I am very, very happy with these!
