STEP UP transformers ??


Having followed this forum for many years I value HIGHLY, the views,opinions,and experience of all who contribute regardless of how small a contribution.

My question regards stepup transformers in particular the Auditorium 23 and the BENT MU. Currently my front end consists of a VPI HW-19 Mk4,OL silver,Denon 103 in a panzerholz body.all running into a Audible Illusions M3a. I've sort of narrowed my choices down to these two SUT's.In fact I already spoke to the Aud 23 distributor in my area, what led me to this dead end is the price. For the price of an Aud 23 I could get the Bent MU, which from what I understand is entirely more flexible(variable loading,captured IC's etc) while the Aud 23 is very good it is made expressly for the DL one-oh-three, and maybe the Ortofon SPU.
I'm sure some say it's a no brainer get the 23 but I don't plan to stay with the Denon forever. I want to make this my last SUT purchase (maybe next to last) as my phonostage may need to get addressed within the next year.
So has anyone had an opportunity to cross reference these 2 excellent SUT's? Also I've heard Audio Note has an excellent pair of SUT's.
Any help would be advised.I know I am leaving out quite a bit of details but that's the long and short of it.
Thanks in advance for you Help

Let me try and clarify some misunderstandings- The Auditorium 23 model 103 step up transformer was voiced around the Denon 103. Every transformer must be voiced around something. This does not mean it can't be used with anything else. Universal doesn't exist. We've used the Auditorium 23 103 transformer very successfully with many cartridges like EMT, Shelter, Benz, Lyra, Magic Diamond, Dynavector and many others.

AI has an excellent high gain moving coil "gold" phono board for the M3a that goes for around $500. It's a SS board that is added to the existing phono stage. It's very nice sounding and was designed by John Curl. I believe it raises the total phono gain to 60 db, more than enough for the denon.
If you plan to upgrade the phono preamp any time soon, I would hold off on the transformers until you have that preamp in hand. The Denon is not so low that you can't run it straight in with many preamps, and if you can do so it will be more transparent, with greater impact and bandwidth.

If you keep your phono section, then it sounds like you may need a transformer. I will second the Jensen transformer vote; they are some of the most neutral we have seen.

thanks for clearing that up , what do you currently use, reccomend ,and with what results?
In the not too distant past I was considering the K&K, I just got side tracked by the Aud 23.
