Best MC step up transformer


I am trying to find the MC transformer for my system. Now I am using Koetsu Urushi + Audio Research Phono Ref 1 with Jensen inside. The sound is pretty good but as always I wanna make it better. I've tryed to use old Koetsu MC step up trans but was unhappy about it. The sound was dull, not clear. When I've looked through ebay and audiogon, I've recognized that they are a lot of unknown for me variants (from 6k$ kondo to 100-200 $). Could you advise the best variant from quality/price point of view ?

Least money expenditure is the Quicksilver. Order with RCA's on both sides. No captive cables. Then grab .5 meter of the Neotech two conductor 22 awg solid silver interconnect and build your own cable if possible.In my experience all coax wire is inferior to two conductor with shield wire. The Neotech is very low cap also

@shmelev_dm Whatever transformer you get, keep in mind that loading it correctly will be the key to getting it to sound/perform correctly. This is why the spec sheet as @syntax points out is so important.

Jensen Transformers has a pdf file that shows the correct loading for their transformers (which is a thing that changes depending on the impedance of the cartridge).

Your Audio Research has 47dB of gain in MM mode. That is a bit higher than a normal MM phono that has 40db.  You  also did not specify which Urushi you have. It is important to know that so you can get the proper match.

 

The best, well thats debatable. As mentioned by leemark, the legendary Stevens and Billington tx103 SUT's are as good as it gets. But you can only buy them through Music First now in their own device. I owned the Bent Audio SUT's that used the Stevens and Billington tx 103's. Long out of production and hard to find on the used market. Very high on the "cool factor" and exceptionally well made. 

If you can afford it, the Ypsilon Moving Coil Transformer is as good as your going to get in whats available retail. Used, almost never find a used one. 

 

Dear @charliee   : The best SUT is NO SUT.
