You might want to ask Marco which one he would recommend as he uses a 103 and has used at least a few of those SUT,s although now I think he uses a headamp.

I wrote this page all about choosing transformers for Denon cartridges:

Did a Google search not come up with the page? I'll have to have words with them about that :lol:
Pretty much any turns ratio between 1:10 and 1:20 will be ok and the same range will work for the Audio Technica too. The 1:10 end of the spectrum will give you less voltage into the phonostage though not enough to be problem, but generally a lower turns ratio gives a better frequency response (all other things being equal, which they never are).
Andrew,
I have read your page, which was very informative.
I am tempted by the MCL, but still have doubts about SUT Vs Headamp.
The thing about decent SUT's, is that they hold their value, so should you buy one to try at a sensible price and decide against it, you can re-sell it at no loss, apart from postage.
We have a distributor in France who may be able to arrange a SUT/Headamp demonstration for you

Or you could ask for opinions here regarding SUTs and headamps but I suspect you will get a 50:50 split with half saying that nothing can beat a SUT and the other half saying that SUTs are rubbish. OK, maybe not that polarised, but enough conflict to leave you feeling none the wiser.
Are vintage Haufe SUTs worth looking at?
Yes, as I mentioned in my post above, the Haufe T-7883s are ideal for the Denon 103. They are used in the well-regarded Auditorium A23 SUT, which for many was the SUT to use with the 103 and 103Pro.
The Altec 'Peerless' range of SUTs are also well regarded: Cinemag being their modern equivalent (Altec sold their transformer division to Cinemag).
And there are a couple of Lundahl transformers that are also popular with Denon 103 users.
Thanks Barry.
I have just bought the Haufe SUT. It is a 1:20 version though, but was not that expensive.
That leaves me enough cash for a Rothwell Headspace as well.
With Denon 103R I used Rothwell MC L . Suited my rig to make quick transients staging and tight bass from valve Ear phono.
The SUT has arrived.
I have plugged it in, and I am listening to the first few tracks. There is no noticeable hum, and it sounds quite good so far.
