“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.”

“This tube improved the midrange clarity and musicality over the stock EH and the Gold Lion tube in my Auris Nirvana headphone amp.”

“Bought 2 platinum pairs around 2 years ago. Put them in the front 2 slots of my pl Dialogue premium hp amp &pl Dialogue premium preamp. Amazing sound across the audio spectrum. Gear &tubes still working &sounding excellent. Great gear,tubes, investment. Once the great nos tubes are gone, that's it. Brimar 4003 really are special. If you get more, let me know!”

“I'm sooo very happy that I purchased a matched pair of these for my Yaqin MC13-S amp to replace the stock Chinese tubes. The air in the mid-range was almost too much at first, but the tubes settled down after several power cycles over 10 or so hours of playing. All I can say is wow. In addition to the Brimar's I did go ahead and order the Russian Mullard 12AX-7's. This combo has proven to be the magic bullet with my setup (Marantz pre-amp, MC13-S, Cornscala speakers) - - fully articulated bass, liquid and airy glorious mid-range. Need I say more? Kevin at UA really knows his stuff when it comes to tubes. Thank you!”
