“My first experience with tube rolling. Bought a pair of these for my PrimaLuna Dialog Premium HP Integrated and replaced the stock gain tubes (front 2). Wasn't sure what to expect, and was pleasantly surprised with what I heard. It's not that it sounded so much 'different', it's like there was more of what I already loved about the HP. Maybe a slightly enhanced midrange, maybe a slightly smoother top end - it's hard to describe but very enjoyable to listen to. I loved my PrimaLuna with the stock tubes, but after hearing the Brimars, I'm not going back.”

“Rogue ST-100 My system was sounding a little clinical and I needed a 12au7 to help smooth off the sound a little and create a more realistic, deep and engaging sound stage. These did the trick. Shipment came on time, great condition, etc. Thanks”
