I agree with others on their adulations of the ARC Ref 3/3SE phono stage (I have a 3SE). It will ascend you above the fray of the ~3K phono stages. It was a big difference when I upgraded from $3K stages to this next level. Also my VAC Renaissance SE phono is above the fray, just a different voicing than the ARC and a bit more fidgety with tube rolling :)
I also prefer using a quality outboard SUT, even with the 3SE. But it’s absolutely not necessary, and very specific to your cartridge choice.
A SOTA Nova with a great vintage arm (ET2, FR64fx, etc) and MC cartridge (your choice - I’ve successfully used many) will absolutely scale brilliantly with a top class phono stage. I know because I’ve tried that. It’s uncomfortably close to my Clearaudio Master Innovation lol.
