Anyone here using Bent Audio MU MC into Modulus 3a

Mid40sguy - To clarify, the TX103 that I am refering to is the same as what you are calling the MU MC unit. Enjoy!

Mid40sguy - When I had a superb prototype MM phonostage to try, I did so with a 1:10 Bent Audio TX103 with the copper option (never heard the silver unit). At that time I compared it to the Classe Audio NIL and an Ear MC-3. I now have a MC phonostage so the BA unit does not get as much use as before.

I do not know if the 3a has both MM and MC inputs. You will have to determine which gain option, 1:5 or 1:10 is appropriate if you only have an MC input. Via the MM input that is wide open at 47k Ohms, you cannot go wrong with the TX103. In my system it outperformed the other two units available to me at the time. The added convenience/benefit of it having a leadout wire eliminates the need for an additional IC. Further, the cartridge loading posts along with the resistor set the manufacturer provides allow you to dial in your desired cartridge loading.

You can also get a TX103 that allows you to switch between one of two gain settings. Happy listening!
