I have been using the H-Cat phono for several years. I has the same character as the P-12BX line stage, namely very transparent, open, and clear. It has excellent top and bottom ends.
I have not tried other phono stages lately but were I to do so, it would be the Einstein Tube. I have heard it in other systems and can say I heard how quiet it is and been impressed with its sound. I also have friends who rave about it saying the reviews which are raves fall short of telling what it is capable of. Until I try it in my home, I will not know whether it has the "magic" of the H-Cat.
