“Remarkable tubes. Truly rounds the system out. Exposes a extremely analog smooth warm sound. Rich texture. Excellent fit for my Evo 100 mono blocks. AS.”

“This is why I only buy tubes from Upscale Audio. I wanted a specific tube for my Evo 300 integrated, and I’m not going to say what that tube was. Needless to say they would’ve been a lot more money for these specific tubes, I thought I needed. But was told the Kt-66 would work better and I would enjoy it more because it’s working more within the parameters of my amp. How many companies would turn away $350 on a sale to do something better for the customer, not many. I can think of a lot of places that would’ve sold me those tubes. And I would’ve been unhappy running the those tubes. This is why I shop upscale for tubes, they know their shit!”

“Used these in my Line Magnetic 845IA to replace failed stock tubes. After the better part of 100 hrs, they still sounded a bit thin, lacked dynamics, and were somewhat 2 dimensional. I purchased these based on the great reviews, and I’m certain that in the right application they are wonderful. The LM just doesn’t like them. Changing to Mullard 6L6GC’s brought the amp back to life. As a side note, several years ago I purchased Gold Lions for the input stage from upscale for the same LM. Those are 5 star and highly recommended!”

“The product has only been used for a short period and still in the break in phase but sounds amazing, I’m looking forward to hearing how good these tubes will sound.”
