Mullard 12AX7 re-issue Cryo vs Non Cryo

Has anyone compared the Mullard 12AX7 Cryo to the non Cryo. While the Cryo exhibits a startlingly clear upper midrange and treble, it does seem somewhat tipped up and a little cold compared to my control tube. Probably perfect for someone but not for, what I consider, the neutral balance of my system. Has anyone else had this experience? I foolishly bought the Cyro version without ever having listened to the non Cryo. Is it worth my while to try the non cryo or perhaps the Groove Tube version?

I appreciate and respect conjecture but would really like some actual accounts if possible.

Appreciatively,

I have the Mullard Non cryo and found that the Ei cryo ( tubeman.com )is a much better tube..Nothing wrong with the Mullard repro but the Ei cryo is much more refined and more transparent... ( Thor T1000 mk2 linestage )

I only tried the Ei Cryo version from Tubeman.com and very satisfied with it ( $50 ish pair ) ..The 5751 Rca black plates ( which I have ) sound totally different..Warmer and more lush ( but a great tub )..I have tried a ton of 12ax7 new production and NOS and found for my likeing the Ei cryo ( as mentioned to be the best ( keeping the sound neutral )the best....

I do think that all tubes mentioned are all good tubes..You really have to keep in mind that most will agree thats its all about System Synegry...I have been using Thor T1000mk2 for many years and have talked with many Thor Users and many of them have there tube set up a little different..Knowone can guarentee a perfect tube in a given situation..All that you can do is offer advise on what "might" work...or what works for them...
