“I think these might be the best bang for the buck in NOS 12au7s.”

“Great tube! I haven't done a lot of tube rolling up to this point, but glad I started here. As described, the mids are unbelievable and really stand out. If these was the only 12AU7 I could ever use I'd still be happy.”

“This tube has incredible clarity and space portrayal in my AN DAC5. I would not call it warm as some have suggested buy smooth is definitely correct. It is the only 9 pin tube that reminds me of a DHT. Very special indeed.”

“I bought 2 matched pairs, I use one pair in my Rogue RH5 and the other pair in my Schiit Valhalla II (with adapters). A nice full bodied sound and not too bright. I have many other of this type and there are so many good ones it's tough to pick a winner but I don't think anyone would be disappointed with the Brimars.”
