Best step up transformer for Benz Micro LP S


I'm owner of a Benz Micro LPS and looking for the best possible SUT .
I have the Lundahl's LL9206 Transformer but i'm looking for LL1933 or LL1931 . Another option is the SAC Thailand SILK Supermalloy MC-step up which is going to be custom for my cartridge . Great option could be the step up from Ypsilon MC10 but is very expensive and never hear of that , Anybody has any experience ? In my system the cartridge sounds best at 370 Ohm load

I use a Bob's SKY 30 with my Kansui. It utilizes Cinemag Blue transformers and is switchable from 1:15 to 1:30. Excellent sound.
I have tested  Lundahll LL1933 whitch is 8X and 16X  . The cartridge actually play good in 10X , and i borrow from a friend the Ypsilon MC10 step up . The ypsilon is the best by far i ever had  listen but is expensive to me !
I'm running my LPS at 1000 ohms on my BAT VK-P10SE with the Lundahl
LL9226 chips.  Sound great to me!

I have a parks audio budgie which is identical to the bobs devices cinemag blue. It costs 400$ one third of the bobs devices. Great bang for the buck. Check their website.
