“Hey! These are the real deal, worth every penny, as you will hear where your money went once they break in! They sounded a bit warm Initially but had plenty of crisp low end and slam once broken in so do be patient during break-in period. Increased Depth of sound and Extended sonic presence of midrange and high end were particularly noticeable for vocals, horns and guitar. Even the sound of Digitally recorded vinyl is enhanced. This one‘s a no brainer boys!!”

“Original two tubes had one bad one. Shipped it back and was replaced. Now I notice that the one original is very black on the top, compared to the replacement.This does not appear to affect the performance, it just looks a little worn compared to the other five shiney silver tops ( four PL and one other Brimar ) Nice clearity and airy, if you will. Nothing to dislike. I would buy from Upscale again and am considering Tung-sol KT120's”

“I have tried several input tubes on a Prima Luna Dialogue Premium Integrated and these are my favorite for their clarity, detail, and black background. They represent a high value upgrade over the stock tubes.”

“Swapped from the stock tube in my Vincent phono 701 preamp. Worth the purchase for me and my setup.”

“Overpriced. I paid for highest grade and these were noisy. There are many better tubes for the money.”
