You either have no experience with an SL12x0 Technics turntable or you are confusing it with a latter day copy by another manufacturer. The Technics SL12x0 series turntables--all of them--do not have--and never have had--a built-in phono stage. They were designed in the '70s and early '80s, when *every* receiver and integrated amp had a phono stage.

I wasn't suggesting that you bypass the phono stage in your Anthem. That should work just fine for your needs. The TT itself has a built in phono stage, and if you can't bypass it for some reason, you can't use the one in the Anthem, or any other one in between. You'll have to plug the TT directly into a line level input on your integrated.
The output of any SL12x0 direct drive turntable is RIAA signal coming off the LP. Period.
There are latter day and cheaper turntables that have built-in phono stages. Two such are the Audio Technica PL120 and PL240 direct drive turntables. They are styled like the Technics and they're decent for the money, but they aren't in the same league as the SL12x0 series when it comes to close tolerances and slick and silky feel. And they were designed after most mid-fi receivers and integrated amps only had line-level inputs.
