“Though still breaking in tubes are already shining very velvety sound. They are very silence and resolving. Once fully broken in, I'm sure they will sound gorgeous.”

“One of the tubes experienced a filament flare-up after 10 hours of use. While I was advised by company staff this wasn't an issue, I didn't like the look of it as none of my other tubes ever did this. I also noticed that my power meters fluctuated at start up using these tubes (which didn't seem right). I replaced them with a matched set of Mullard-made 6060 blackplate 12AT7 type tubes designed for Zaerix.”
