“Installed in secondary postions on a PL integrated 400evo. A great combination with the Brimar tubes as primary. The GEs replaced the stock tubes. I really like the sound. I keep coming back to Upscale Audio for equipment and tubes. Thank!!”

“Using in a brand new Decware ZRock3 after I stupidly broke the tube it shipped with :( No problem, sounding great with the help of the pros at Upscale Audio. Let me also take a second to mention the customer service and support I have experienced over the years at UA - it's absolutely top-notch. Friendly, knowledgeable, super quick responses to pre-sales inquiries and housekeeping issues like when their customer (me) keys in the wrong address. I'll be back!”

“Still in the break-in period so I'm expecting them to open up and get sweeter as they come along but right out of the box, they sound very nice.”
