Do I need a sut?

@rauliruegas as you very well know (if you are as well informed as you claim) MFA is the hi-fi arm of Stevens & Billington, a long established transformer maker. MFA/S&B wind their own transformers to order. The base model, which the 632 series are based around (I believe) is the TX-103, specs on that are available here
http://www.stevens-billington.co.uk/page103.htm

As all MFA products are built to order you can be sure they will match the needs of your cartridge (ratio, impedance, inductance etc).

Anyway I'm not trying to shill for MFA, I'm sure Bob's are just as good, but could not let Raul's slur go by

That's why I mentioned them as experts. I think that not you or me know if inside that is the TX-103 that's a good SUT but: is it the best out there?.

There is something where the designers of the 103 coincide with what I posted here:

"   to maximize bandwidth ", this parameter is extremely important in a SUT and the 103 is not near the Denon or Technics one, even the T2000 makes it better.

I posted more than once in Agon that if I don't owned my active high gain SS Essential 3160 ( up-dated. ) I can live easily using my modified Denon SUT  as a fact time to time I use it.

Dear @folkfreak : Perhaps what has more influence in the cartridge signal degradation levels ( other than its limited bandwindth. ) with external SUTs are: additional cable/connectors and switchs like the ones in your unit.

@rauliruegas as in all things audio one has to make trade-offs. There was a long design conversation with Jonathan behind the particular decisions on what switching and functionality to include given my need for two cartridge inputs. In  a purist world I'd have a dedicated SUT for each and no switching but as the phono stage I'm moving too (VOSS) only has one input I needed switching at the SUT. I did decide against switched gain which was another option. Needless to say all wiring and switch choices are as good as they can be. As to issues with length of interconnect I'm having no issues driving 2M of WEL Signature

Dear @folkfreak : With all my respect to you it's dificult for me to follow your " common sense " to achieve the best for analog. There is no doubt that you have the kind of money to do it but maybe not the rigth advisors to do it because you will add a VOSS phono stage that needs a SUT and al those  will be connected to the AR tube preamp.

You said: "  In a purist world I'd ...."". For me in a " purist world " ( and talking of analog cartridge signal. ) what my common sense dictates is to own the best direct and shorter path for the LOMC cartridge signal and that is: an active high gain integrated PHONOLINEPREAMP with no single cable/connectors/SUT in between and this kind of units exist.

Let me ask: do you really want to achieve the very best analog quality cartridge level signal to listen to? because the " road " you choosed,  and does not matters how many $$$$$ spend,  just can't  help you to achieve that " dream quality levels ".

Maybe I'm loosing something you know that I just don't know or understand.

Regards and enjoy the MUSIC NOT DISTORTIONS,
