## Description

The Mullard 12AU7/ECC82 reissue is a great 12AU7 tube. This tube has low noise and low microphonics. A great tube for Hi-Fi amps and microphones.

Review: Mullard tubes are the best for warm, clear and balanced sound, nice and quiet too! - These tubes are very good! I use these in my vintage Dynakit/Dynaco ST70 tube power amp, in combination with Mullard EL34's and a Mullard rectifier tube. I find that my amp sounds better, and is quieter in terms of hiss/buzz/noise, than with other tubes and I've tried a lot of them. The Mullards give a nice balanced sound with beautiful mids and treble and decent bass. In my case I pair my tube amp with a small subwoofer to get the low end I like. Recommended!
Review: Very Good Tubes - I have an XDUOO TA-22 which I love. I have three sets of tubes for it and these are the most expensive and probably sound the best. The stock tubes were just fine, but a tad bright/clean for me. I like a bit of a stronger bass/sub-bass and a bit of a warm sound. I put these in and let them "warm up" for about 80 hours before I wrote this. The tubes provide a nice texture to the music and seem to fill in the bass/sub-bass just fine. The overall "warmth" of the sound seemed to be there. I listen to all kinds of music but mostly "Classic Rock" and, I feel Classic Rock on a tube amp is just **kiss*. Overall the tubes are an upgrade to the stock tubes and sound good to me. Worth the price in my book.

### ⭐⭐⭐⭐⭐ Sparklingly Great Sound
*by R***R on January 28, 2022*

Terrific buy. Purchased for my Rogue Sphinx V3. Was glad to see other owners in the comment section and their positive experience with these tubes. Ran the stock tube for a year and the sounded great. Then got some elevated rush from one of them and contacted Rogue and got some RCA Cleartops as a premium upgrade/replacement. Really liked their sound as well but had far better soundstage and upper end clarity. From there decided to try some others for the fun of it. Even my wife commented on the sound improvement. The Mullards really shine. Came beautifully packed with a matched pair of Tong-sols as well that I have yet to try. I would highly recommend to anyone new or experienced with “rolling”.
