“Excellent tubes. Running a Primaluna amp with Focal Kantas. I was very surprised to hear a big difference with these tubes than others, including EL34s, and KT66 and 77s. The 6550s are very linear top to bottom, smooth and clear sounding. Highly recommended.”

“Had a 6550 go back prematurely so I ordered one replacement and just like that, my ears are humming again. Thanks for the very fast and friendly service....”
