Mullard 12AU7, Matched Pair

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!

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.

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”.

Tubes do sound different . If you are looking for a vintage, creamy, 70s style tube tone with a fat, warm midrange and bass then these are great. If you are looking for a more bright sound with clinical clarity and a sparkling high end then I suggest you try something else. Reviewed using a Rogue Sphinx V1 integrated amp, JBL 530 speakers via Kimber Kables playing both analog and digital sources. MMF 5 turntable w/ Gold ring cartridge and LPs , Music Hall CD player and streaming through Audio Engine B1. Enjoy !

These replaced my TAD 12AU7 tubes in my EAR834L line stage high-end preamplifier. After about 10 hours of listening/burn-in, they opened up beautifully. They have a tinge of warmth, with great detail, and are not harsh at all or fatiguing. They have great headroom with that live feel that only tubes can give you. They sound less compressed than other 12AU7 preamp tubes.

Running these in a Rogue Sphinx 1 and they sound excellent over the stock tubes out of the box. Tried out the Golden Lions at double the price of these, and not only sounded clinical and lifeless, but also lost a little gain. These are the ones you want. Don't bother with the rest.

Don’t know if I got a bad example, but I had to return them because my Rogue Sphinx v2 far preferred JJ EEC802s or 1960’s nos RCA tubes. One channel seemed to drop the signal a time or two and when working, they seemed to have a raspy edge on some voices. Dunno, but for the price, not taking the chance to keep trying to love them.

Works great in my Cayin HA-3A tube amp. Significant upgrade over the stock tubes.

Poor packaging since it came from America apart from that sound great in the sound system

Seit dem ich diese Röhren verwende ist das Zischen der defekte Röhre in meinem Kopfhörerverstärker weg. Zudem ist das grundrauschen des Verstärkers massiv zurückgegangen und der Dynamikumfang bei der Wiedergabe hat sich leicht verbessert.

価格は高いが、音質はずば抜けている評判通りでした。

Nice sounding tube thanks great match Tonal tubes highly recommend buying from them worth every penny fast shipping also they are the only place to get tubes they will beat price of any other seller I buy all my tubes here best warranty

１２AX7の球転がしでKT88と同時期に購入しましたが、 音痴の自分には余り判りません、ネット観てると実際本当に判って 記載してるのかなと思う今日この頃で、TRK-3488もキット 購入、現在オブションの抵抗も無き為、実装の物で組ました 恐らく、実装の状態が真空管AMPもベストかなと思います。
