I'd be careful about impedance compatibility between the phono stage that you choose and your Ayre integrated amp. The Ax-7e's input impedance of 20K unbalanced and 40K (20K per phase) balanced is too low to be optimal with either the Herron or ARC phono stages that have been suggested. Or with many other tube-based phono stages, for that matter.
Also, +1 re the ART9, which I use in conjunction with a Herron VTPH-2.
Good luck. Regards,
