User Experience on Sophia Electric Blue Glass 6SL7 Tube

Hi Sue,

Once again, I am thanking you for an amazing tube (6SL7). I could not believe what my ears were hearing! From the moment the music started, the difference between the Sophia 6SL7 and the Tung-Sol was incredible — the bass was so much tighter and punchier, the mids and highs were so extended, and the vocals sounded so natural and clear. This is only the third night. Without a doubt, it’s the best I’ve ever heard — and it’s also a beautifully looking tube. Thank you for another wonderful experience.

Regards,

Dan from Australia
