A SUT will alter the sound of a cartridge slightly, as the loading is marginally different between each one.
We are talking minor differences.
Having a SUT will give you greater flexibility to try any MM only stage.
I have a SUT that you can borrow until you find one to buy if you wish.

I love Hendrix for so many reasons. He was so much more than just a blues guitarist - he played damn well any kind of guitar he wanted. In fact I'm not sure if he even played the guitar - he played music. - Stevie Ray Vaughan
