“After breaking in, bais is very stable. Tubes sound much better comparing to old stock tubes from ARC which is expected. But buying from upscale give me the peace of mind that I am getting top quality stuff for my Ref75SE.”

“The sound is proving to be impressive after a few dozen hours. I’ve docked a star because one of the 4 tubes I received is noticeably smaller in its egg-shaped glass (but the internal parts look the right size) than the others which gives an unbalanced appearance to the amp. Maybe I was given an older tube from a different production run.”
