Step up transformer recommendation

I am looking for a SUT to work with my Rega apheta 3 and audio research PH3SE.  Had the apheta 3 with the Rega Fono MC just did not do it for me.  I am thinking I can use my PH3SE but need SUT. 

I liked the way the PH3SE sounded with REGA Exact 2.  Upgraded to Apheta 3 and Rega Fono and it was not the upgrade I hoped for.  Want to dump Rega Fono and use PH3SE with Apheta 3.

Any help please.

Thanks, Tony

A step up of between 1:15 and 1:20 would be the best match.

The AR Reference 3SE has

Gain:

Selectable 51 dB (Low) and 73 dB (High) at 1kHz BAL; 45 dB (Low) and 67 dB (High) at 1kHz SE. (MC and MM compatible).

Input Impedance:

47k Ohms and 100 pF SE. Selectable loads: 1000, 500, 200, 100, 50 Ohms, and Custom.

You would use the 45 dB setting and 47K ohm setting with a Step up transformer.

 

If it is the  PH3-SE, with a fixed setting of 54 dB of gain, then you would probably want to use a 1:5 or 1:10 step up.
