“I swapped the Brimar 12AU7 tubes for the stock tubes in my PrimaLuna EVO 400 preamp. I immediately noticed the Brimar tubes gave a smoother tone with improved imaging. I like the stock PrimaLuna preamp, but the Brimar tubes have a more appealing sound in my system. Thank you Upscale Audio!”

“Absolutely fantastic upgrade to my Cayin HA 6A tube amplifier. No noise in any channels, pure analogue bliss! Recommended”

“utterly fantastic tube. Used in the cathode follower stage of an all triode RIAA that is very revealing, and this tube does not disappoint.”

“These have made the biggest improvements than any other tube I’ve tried in my primaluna evo 300 preamp. They have removed the little bit of harshness I was gettingvwith my Cornwall 3’s. There is much more instrument separation, more detail, a smoother top end, and more bottom end. One tube came to me cracked but Upscale quickly fixed that and sent me another.”
