SUT to MM cable? what should i get? cable mis-match


So I took thee plunge on the advice of some very helpful audiogoners and decided against the FR step up transformer. I decided to first try out an Entre ET-100 as it has inputs for 3 arms with difference impedence settings.

My question is this, having regard to the arms and cables i have acquired. I have a :

- HELIUS OMEGA with a silver cryo cable which goes from tags to plugs.
- FR64
- Moerch DP6
- SONY PUA7
- Mission/Jelco
I have a few different cables available to me:
1. Nordost Tyr
2. Cardas Golden Reference
3. TCI
4. Townshend

What kind of cable do i need from SUT to mm stage - tonearm cable? normal shielded interconnect?

Silver or copper? - length? Any specific specs - ie low capacitance???

Dear chakster, How many tonearms and cartridges our members
own according to you? ''at least 4 inputs is a must have''? 
Must have for what? 
Inputs on LINE LEVEL PREAMP that can be used for DIGITAL too, not only for analog. I use all 4 for analog only, but i have 2 turntables with 4 tonearms. 

The OP own 3 tonearms, so he could connect each tonearm with separate phono stage (or sut and phono stage) to line level preamp. 

It's not necessary to have a SUT with 3 inputs, it can be 3 different separate devices (SUT, Headamp or Phonostage) connected all together to ONE line level preamp
@nandric - seeing as you are goading me into an answer...

...

My reasons for the ET-100 - which i don't have to justify, but i shall so that my question is in fact answered about cable is as follows:

1. it's not so much comfort as a lack of space getting to the back of my components as space is a problem.
2. In addition to this different cartridges need different impedences.
a. The Whest can be altered on load reasonably easily -
b. the Vendetta is more of a pain and requires a multimeter to do it very accurately along with taking the lid off.
c. With 2 young kids and a demanding job i get the best of 1-2 hours to listen. I don't want to sit their fiddling around every time I want to try and listen through one of my other decks - not my idea of fun - i enjoy listening to the music.
3. If i was to be tied down to one input on an SUT I wouldn't bother and just stick to a single to the phono stages I have - which may still be the best sounding.
4. On the other thread i understood that actually the FR is not that brilliant and in fact the likes of Denon Ortofon and Entre are better options.
As I am trying out - i went for the Entre.
Just because I have put out a question, digested the answers, and followed one route does not make me a luddite. As it happens I don't change components every day and amass components like many people. I am entitled top experiment as well
@lohanimal
Given that nandric appears to have not experienced an Entre ET100, then his opinion is speculation at best.
The Fidelity Research step up transformers I have experienced, including the top non switched ones with their matched FR cartridges, were awful - demolished by vintage Peerless’s and newer Jensens.
If you talk to cartridge designers you will find that they have theoretical preferences on optimum SUT depending on the actual cartridge design. For example I have seen JCarr theorise that specifically a toroidal based SUT would give the best outcome for a specific cartridge. This is based on the type of distortions inherent in toroidal vs other transformers and vice versa.
Transfomer matching to cartridge is much more than gain and impedance and in my view is Russian roulette. There never is one best solution.
@lohanimal I have an Entre Et 100 as yours , and very happy with it, actually I bought it from Raul a couple of years ago,  I also have two turntables and 3 arms so its very convenient. My only recommendation (and actually was Raul,s ) is to rewire internally with better more recent shielded cables.  In my case i did it with discovery cable plus 4 and very happy with the results. the technician that did the Job told me that the selectors and transformers inside are top notch even by today standards. Another friend of mine also bought one from a seller in Japan and had it rewired by Steven Leung of VAS and is very happy with the results.  BTW Entre was a company led by back then by Matsudaira San of My Sonic labs.  Enjoy,
