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.

Exactly what I was looking for, sounds great on my Crack amplifier with a 5998.
