Do I need a sut?

Dear @folkfreak : With all my respect to you it's dificult for me to follow your " common sense " to achieve the best for analog. There is no doubt that you have the kind of money to do it but maybe not the rigth advisors to do it because you will add a VOSS phono stage that needs a SUT and al those  will be connected to the AR tube preamp.

You said: "  In a purist world I'd ...."". For me in a " purist world " ( and talking of analog cartridge signal. ) what my common sense dictates is to own the best direct and shorter path for the LOMC cartridge signal and that is: an active high gain integrated PHONOLINEPREAMP with no single cable/connectors/SUT in between and this kind of units exist.

Let me ask: do you really want to achieve the very best analog quality cartridge level signal to listen to? because the " road " you choosed,  and does not matters how many $$$$$ spend,  just can't  help you to achieve that " dream quality levels ".

Maybe I'm loosing something you know that I just don't know or understand.

Regards and enjoy the MUSIC NOT DISTORTIONS,

@rauliruegas do you have some sort of problem with me? Have I ever commented on your system or tastes? I’m happy to invite you round to hear my system if you’re ever in the Pacific NW but in the mean time could you do me the courtesy of refraining from insulting my audio preferences or experience.

That's what Raul does. Apparently him and a friend came up with a solid-state phonostage so now all tubes are crap and backwards technology.  He focusses on the fact that the specifications of solid-state are better than Tubes regarding frequency response and distortion but conveniently ignores the fact that the ear hears different distortions differently.  
He is  probably one of the, if not the most annoying opinionated individuals on this forum. 

Dear @folkfreak : No single problem with you or your system, I was only trying to help for its quality level performance be better if any.

You are rigth and my apologies to talk about in a public forum. I'm sorry for that, my fault because I took in count only what I was thinking with out take in count your legitimate side.

I know you are a decent, honest and mature human been and a true audiophile and music lover.   

Again very sorry to disturb you in that way.

Sincerely,
R.

I have a Bob's devices 115/130 passive SUT running into the Herron VTPH-2 from a VPI Prime Signature with a Van den Hul
Stradivarius cartridge (.38mv) and it sounds terrific at 1.15 step up.
If you want talk with someone who KNOWS about SUT's talk with Bob at Bob's devices. He can be very precise about what will work with your cartridge and system.

I have no business connection with Bob or Bob's devices. I do own one.
