“Over the past few months I have been auditioning current stock 12AX7's for my SixPacs. The Mullards were last on my list, but they are the keepers. Smooth and natural. Sets the soundstage back the way I like it. Excellent detail, timbre, especially on piano and vocals. Unexpected fullness and body in the mid-bass. To my ears these are a tube I can live with and listen to for hours without fatigue. Let them burn in for at least 20 hours before you form an opinion.”

“I am not a tube roller. I donÂ´t have the means or the oppertunity. But I wanted to replace the first 4 tubes in my Rhea phonostages. And I am very pleased. More detail - less hiss - more texture and better seperation and sence of soundstages. I did go with the premium grade and had them cryogenically treated. I am very pleased.”

“I have rolled few tubes at this point in my Vincent SV-236 integrated amplifier but these Mullards (I picked up the highest grade) were really shocking in their performance improvement over the stock tubes and even vintage Amperex ones I've tried. The midrange is straight up holographic and represents easily the strongest aspect of its performance. This is not a laid back sound, but is not forward either. There is definite depth to the soundstage as well as solid, focused imaging. The tonal colors and timbres really shine with these. What a find!”

“After trying RCA black plates, EI, Tungsol reissue, Gold Lion Reissue, I always seem to come back to these tubes. They just seem to work well with all types of music. The RCA's can be very ear pleasing but tend to be picky on the type of music being played. The other tubes just don't have the full tone that the Mullards have. Just need a few more reissue 12AU7 and all will be good. Currently using the gold pin JJ 802s which seem to work well with the Mullards for now.”

“Probably not a fair comparison, as so far in my limited experience vintage tubes (GE's and Sylvania's) have been night and day better than anything current production, but based on the reviews here I thought I'd try a pair of these in place of my current GE 12ax7 long plates. What I'd hoped for was the warm, sweet, detailed sound previous reviewers were reporting with these Mullard re-pros. What I got, at least on my system, was a smaller, curiously flattened soundstage with a sound I'd characterize as soft and dark. If you're trying to tame a very bright sound, these may be just the ticket. To be clear, the GE's are hightly regarded vintage stuff and well broken in, and these are Mullard re-pros with only arbout 10 hours total, so may not be an entirely fair comparison. I just know no tube is forever, and had hoped these would be a good replacement pair to keep in reserve--but based on listening so far, in my space on my equipment, I guess I'd better just stock up on the GE's while they are available from Uncle Kevvy.”

“These are amazing. They are quiet. They are well made. And the sound! Full deep bass wiout bloat. Classic Mullard mids to die for! And the MOST beautiful highs. Clear, balanced, unforced in any way and supremely easy to listen to. Overall I rate these as being the best of the currently available 12AX7''s and better than most of the NOS 12AX7s I have owned and listened to.”

“I have rolled tubes in and out of my PL dialogue one liking the different flavors of sound, BUT this new mullard reissue is a home run. Sweet smooth highs and very nice detail, air and warmth from top to bottom. The bass is tight without any bloat at all. Just a wonderful sounding tube and they are dead quiet and seem to last, these are staying in here and trust me I have plent of NOS on hands These are that good, try a pair your ears will thank you”
