“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.”

“Sound great, but I have not had a chance to roll them to see how much of a true difference they make.”

“These are outstanding tubes! These tubes are very quiet with no noise or microphonics whatsoever! As soon as I started using these tubes I noticed an improvement in clarity, instrument separation, and detail retrieval. I also noticed the warm nature of these tubes especially in the mid-range. Mid-bass is very prevalent but might not be everyone's preference. These tubes should be perfect with Sennheiser headphones or others that are light in the bass department. Very musical tubes. Highly recommend.”
