Mullard 12AU7 Reissue | A Very Engaging Tube

by -

I wasn't happy with the stock tubes (Shuguang) in a new PrimaLuna Evo300 Hybrid amp. Too clean and clear (not bright) for me in my system. It felt just a little forward and like I was being a little bit shouted at at times. Tried two Mullard 12AU7's in the innermost sockets. The highs and mids wonderfully meet my hopes and tastes. There is sweetness, warmth, richness and a softer comparative sound, engaging and musical. I however thought the bass was a little loose, or a little bit woolly. If I don't find something even more suitable, I can likely live with this as it is very good, allowing me to enjoy music. So very close to being job done. I'm not an audiophile so please take or leave my opinion, but hopefully this helps someone.

Mullard 12AU7 Reissue | The bass is amazing and overall integration is...wow!

by -

Just received a quad of this MU-12AU7 tube, and right out of the box into my Schiit Freya+ preamp, and they outperform it's price range, way way above. The mid range is clear but unobtrusive, the upper ranges a sprightly clear, to my liking, it's not bright but expressive enough to give music a liveliness. On the overall, it leans slightly to the warm side, and the mid-low bass is the Star! It's the best 12au7s that I've had. The other one is Northern Electric 12au7 (make sure you pay for the matched and balanced); this one the upper ranges are more open and transient. But, it's no match to this Mullard's bass! No tube is perfect right? :)
