Mullard 12AU7 Reissue | The bass is amazing and overall integration is...wow!
by Barney Wee -
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? :)
