Ortofon T20 or T30 for MC20 Supreme

[355F1]

I want to get either an Ortofon T20 or a T30 for my MC20 Supreme.

Which transformer should I choose, just in theory but not in practice, according to the manufacturer's specs?

The MC card of my amplifier does not have enough gain

What is the gain?

0dB 210μV
3dB 150μV
6dB 110μV
9dB 75μV
12dB 54μV
15dB 38μV

On paper it looks like to be fine but in reality I do not like the sound.

Which is the Zinput of you MC card?
In general is not possible to use a trafo to connect the MC input.
With T30 you can use the max ratio ( 3 ohm) and connect it to MM section
