0.12mv is indeed way too low for just 60db gain.
My Chinook has the same max gain and I went with a Denon SUT to boost signal on my 0.24mv cart.
This worked very well so I would think the art7 would work equally well as with the SUT I still did not have to use much actual amp volume to get very decent sq levels.
