Doesn’t the REF 3 already employ an SUT when running through their MC input. I think at times it’s overlooked, but most tube phono stages have built in SUT’s. Manley, Aesthetix, and as all who frequent A-gon know, Atma-Sphere, do not use an SUT. IME, 68 db should drive a .3mv Benz. Not an easy task for a tube stage without an SUT, but 68db should work, pending it's quiet enough for you. I drove a Benz Ruby 3 with a Lamm LP2, and the 57.5 db gain was not quite enough....

When is it time to consider adding a SUT?
I have an ARC reference phono 2 and am about to take possession of a Benz LPS with a low output. I have heard that installing a SUT such as one from Bobs devices can help the phono pre and provide better end to end performance. Would this help a quality phono pre like the ref 2?
