“I have put about 50 hours on these tubes in an PrimaLuna Evo 300 power amp. I can’t say that they are mind blowing, or changed the quality of the sound in a positive way. There is nothing really wrong with them. However, I really prefer the PrimaLuna branded tubes. Maybe they will be better in a different application. That said, Upscale Audio has always done me right. I got what I paid for in a timely manner. Everything was packaged professionally. No real complaints. I’m just not really impressed with these tubes.”

“I bought these to add a bit of high frequency energy to my sound. They were too bright there, but moving them to the secondary preamp tube sockets in my PrimaLuna Dialogue Premium HP Integrated did the trick.”
