5 of 5 Brimar CV 4034 December 8, 2016
Reviewer: PureAudio from Scotts Valley, CA United States  
I put a quad of the Brimar CV 4034 into the front end of my Zanden Stereo power amp and quickly found them to be the best 12AU7 type I've yet heard. Easily surpassed previous trials with top rated Philips and RCA brands in all parameters.

High in resolution and control and low in distortion while being quiet.

Thank you.

5 of 5 Superb Tube! December 3, 2016
Reviewer: Brian Breslin from Vancouver, BC Canada  
I bought a pair of the Brimar 4034 from Tubemonger.  They are brilliant.  After placing them in the front two positions (of the six 12AU7 in my Primaluna Dialogue Premium) the sound is now more delicate, with life-like rendition of human voices (both male and female), and a wider, deeper soundstage.  After a recent unpleasant transaction with another Ebay seller, this was a great outcome!

5 of 5 Audio Excellence-BRIMAR CV4034 November 15, 2016
Reviewer: Mike G from Anoka, MN United States  
First off-Great flying lead to pin conversion-First rate job! I replaced a pair of BRIMAR 1960's CV 4003's in my PL Dialogue Premium Preamp with the  CV4034's in the front slots. Total sonic improvement across the audio spectrum, better bass, naturally realistic midrange, & stunningly clear & detailed top end without glare or tizz. The best 12AU7's I have ever used, totally impressed! I got a second pair for the front slots in my PL Dialogue Premium HP Amp. Like others have said, just put these in you're gear & enjoy the music in the way it is supposed to sound. Flat out AAA+ recommended! They arrived quickly, safely,& packaging is the best I've seen. Great company, I'll be doing business with you again soon.

5 of 5 Excellent tubes February 21, 2014
Reviewer: Jeff  
These are the best 12au7 type tubes I've tried by a long shot.  I have a Unison Research Simply Italy amplifier, and these tubes absolutely brought it to life.  I tried a number of other highly regarded tubes including the RCA clear tops, Mazda Cifte, RT, etc, but the Brimar are in an entirely different league.    They are crystal clear, detailed and just beautiful to listen to.  Zero listening fatigue, and I can hear into a recording like never before.  Don't waste your money on the others.  Just buy these and be done with it all.

5 of 5 Audio Bliss February 8, 2014
Reviewer: Finn Mölmen from Oslo, Norway  
A week after ordering I received a pair of nicely packed Brimar CV4034’s with bakelite base and new pins, all shiny and appearing brand new. They are to replace a pair of Brimar 13D5’s, that unfortunately create a steady hissing sound.
In my preamp CV4034’s possess the supreme, sonic beauty I have grown so addicted to with the 13D5’s, and sound even better than the 13D5’s! And they are of course dead silent.
With the new old stock pin-fitted Brimar CV4034 in my gear
• dynamics are enhanced,
• treble clarity is almost paranormal yet sweet and pleasent,
• midrange presence makes me fall in love with the singers through their voice,
• bass is manly yet perfectly controlled to make the music play with enticing rhythm,
• sound stage is revealingly three-dimensional,
• there is no instrument meandering, the positioning is rock solid.
Every other pair of tubes I may buy in the future will only serve to prove the supremacy of these tubes. A real bargain – a tremendous upgrade.

5 of 5 Outstanding Premium Tube Over all Other Tubes May 20, 2010
Reviewer: David Picarsic from Augusta, GA United States  
I am going to make this simple. All the great things you have read about the siemens/telefunkel tubes, multiply that by 2 and you get Brimar CV4034. This is a must have to step your highend system to the next level.
