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
- 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???
Short, very well shielded with nice RCA connectors is what you need.
Silver or Copper is a matter of personal preferences. 
I think you made wrong decision. Depending from impedance
of the used carts you should chose for FR low, mid or high
SUT's versions . Those are ''purist'' in the sense that no
additional soldering points or switches are used. All those
switches have aluminum parts in the signal path.
By FR kinds one need only to check output cables and replace
them if corroded.
Raul mentioned this many times.  
In addition to short and shielded, low capacitance is critical.  This is a high impedance node which makes it ripe for hum pickup and premature rolloff / phase issues from excessive capacitance.

If truth be told I want to give it a try and have 3 inputs from one device - because i have more than one turntable. My alternative was to by something like a MAnley Skipjack - which remains an option. If i don't like it then it's not so costly and I haven't lost a penny.
lohanimal, you are confusing different impedances with different
TT's. Different impedances are meant for  cartridges with
different impedances. Say low ,mid , an high impedance carts .
Not for different TT's.  The switch on your SUT is meant to switch
between carts with different impedance. 
@nandric I can use one sut with three inputs for 3 arms that means 3 cartridges - i have one turntable with two arms and one with a single arm next to one another - they can use the SUT. I am a bit puzzled with how you think i made an incorrect choice given that amongst those recommended was an Entre over and above an FR. I did indicate that i wanted a multi input SUT, otherwise i would have just got a switch box

lohanimal, Well I owned FR- frt 3 and 5 with switches. By inspecting
their inside construction I have seen more soldering points then
by any tonearm with removable headshell.  What is more I got advice
from our ''old member'' Dertonarm who preferred FR ''everything''
above any other products. He advised FR- XF-1 (L)  which he used
himself. But my problem was that I own MC carts with different
impedances such that I would need all 3 (+ m and h kinds) . 
I also own Kiseki step-up (low impedance) made by Kondo san
(AudioNote) for his friend Van den Dungen. However I use step-up
only for my Ortofon MC 2000 with 0.05 mV. My phono-pres can
drive all other MC carts . So my advice is based on my own experience . 
 As should be the case with all advices. 
I see your preference is based on your ''comfort'' instead on
''optimal results''. Sorry for my misinterpretation. 
In my opinion a line level preamp with at least 4 inputs is a must have, then we can use various phono stages and SUTs to connect them to the line level preamp where we can switch between 4 inputs. 

SUT or MM phono stage can be very small and to find what's the best we have to try many. 

With 2 turntables and 4 tonesrms i am happy with Pass Aleph L pream with 4 inputs where i can connect all my phonostages (with or without SUTs or Headamps) to switch between 4 tonearms. 
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
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,
When I needed to decide which phono-pre to buy one of my
conditions was two inputs for the two tonearms I use by my
Kuzma Stabi reference. Next to ASR Basis Exclusive which
consist of two separate but identical pre-amps there was one
other German phono-pre in tube like construction which got
very good reviews .  I forget the name but there were two
version one of which was fully symmetrical. I noticed, uh, 
''only one input'' on its back side and wrote to the manufacturer
asking ''obvious question'' if they would be so kind to make
one additional input for me. To my big surprise the designer&
owner refused refused to do so. According to him this would
''ruin'' the performance . So I bought Basis Exclusive on which
I connected Reed 3P in ''balanced mode'' with 100 Ohm and
the other , Sumiko 800 in , say, RCA way, with 500 Ohm.
I hope dover will be so kind to again comment on my choice.
BTW my FR SUT choice was based on Dertonarm's advice .
He was a kind of ''our authority'' regarding anything FR's.
@lohanimal Send me an inbox with your email and i and send you a picture. Its fits very tight , but can be done.
