I have been following this thread, so I have to ask, for those of you who have built it, how does it compare to the Steve Bench 12AY7?

That 12AY7 cascode was what a mate had. It was best to all other tube phonos he had made, they were several well known schematics. But he sold it soon after he had made the Itch.

OK. I guess I need to build another tube preamp (I have the 12AY7 cascode and a Siren Song). So time to order parts. Is the value for the coupling cap between first and second stage correct, 47nF? Seems a little small. Also is there a schematic for the version used SSHV for this design?

47nF is correct. Gives opportunity for NOS small Teflon. There is high enough impedance to couple to. Can go up to 0.1uF with somewhat less VLF roll off control.
