ZYX Premium Cartridges

These new premium Airy 3 and 4D cartridges have been out since last fall.

Has anyone bought one and how do they compare to the older current versions?
Maybe the "magic" starts with the UNIverse, because my indirect experience with that cartridge suggests it is uncannily true to life, mounted in a Talea tonearm. What tonearm(s) did you use, David or Sbrown?
Zyx is for those who haven't heard a properly set up Lyra.
Lew, I use a Graham Phantom and I've heard the Airy 3, Atmos/4D and Universe in both Grahams and Basis Vector arms. I have no doubt that the uni sings in the Talea - a friend has an Anna in that arm that I am enamored with.

Judyasblues - your snarky reply is a testament to your ignorance as there are trade offs with both the ZYX's and the Lyra's. Ones personal preference and system compatibility dictate which set of limitations one is willing to live with.
Judy oft snarks,
With vaporous pith,
Her curt remarks,
Of content aren't with.

Doug, I like your smiley face better than the last line of your quartet. I am still trying to parse it, but I get the gist. Judy was just being provocative, I think. Judy, Judy, Judy, you are entitled to your opinion, however subjective it may be.
