John,
FWIW, you don't need a "MC phono" since your cart has 1.2mV output. Both the EE and the Concerto will have enough gain for your cart. The Concerto has two outputs, one with 45db gain (iirc) for high output MC and MM carts and one with 54db gain for medium output MC carts.
I've poked around inside the Concerto and it seems very moddable and has a great PSU, if you are into modding/tweaking. I have no experience with the EE.
