User Experience on Sophia Electric Blue Glass 5U4G

The recent 5U4G rectifier tube I purchased arrived in excellent condition. Thank you! I'm using it it in the power stage of my Woo Audio headphone amp, and out of the box it sounds truly amazing. I've lost count honestly (I think around a dozen), but this is one of many tubes I've purchased from you with no regrets. Currently, I have a quad of Sophia Electric EL 34s in my tube amp, your rectifier tubes in my preamp and headphone amp, and a 6SN7 in the preamp. I also have the incredible Magik Box.
