I've a matched pair of Sophia Electric Grade A 6sn7. I've used them in ModWright LS100 preamp for few months. I guess around 400 hours on them. Sophia Electric 6sn7 are very long lasting tubes. They are very dynamic and linear. I also have a create audio/synergy HIFI 5AR4 that I also used with ModWright preamp. Excellent combination. I'll give a good deal if someone buying the 6sn7 and 5AR4 together.
