I have a Primaluna Evo 400 preamp and amp. I really like these two in the front of my preamp. They are extremely clean and detailed.

My primaluna evo300 integrated sounded great with the stock tubes, however these Brimar's in the driver position made a Big difference. Smoother highs with no roll off and wonderful mid range.

My Cronus Magnum 3 12au7 center socket does not seem to like this tube. no matter how many Brimars I have tried there was some small amount of hiss in one channel or another. The manufacture of my amp. sold me a NOS 1972 Sylv. tube that is working out just fine.
