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

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. 

It alllows switch carts and impedenced

@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.
