“In my Cayin HA-6A amp, these sound even better than the impressive NOS Miniwatts!”

“I purchased both Brimar 12AU7 and the Mullard 12AU7 (NOS) to use in my PrimaLuna Prologue Premium pre amp. I’m using the Mullard in the primary position and the Brimar in the secondary. There was a noticeable difference in sound quality. It’s remarkable how much difference these tubes bring to the music presence.”

“I'm no audiophile, but this tube really woke up my music. I have it in a Vincent PHO-701 phono stage, and it's amazing. The music just seems so realistic and vibrant. I can hear shimmer in the cymbal hits I've never heard before, and the kick drums have an added amount of detail that makes it almost seem like I'm in the studio during recording. Just outstanding sound!”

“Placed into my BHK Per. Only @ 10 hrs on them. Immediately notice an improvement in soundstage width and depth. Mids and vocals clearer. Seem to be well worth the cost!”

“Put a matched set into my preamp, and was pleasantly surprised at how good they sound. I have always found it hard to describe sound with words, as words have different meanings to different people. These are a great sounding tube, a very smooth sound. Makes music more engaging.”

“The Mullard CV4003 was always my favorite 12AU7 and I view the Brimar the same. It does everything well.”
