I wouldn‘t hesitate to use a high quality Step Up Transformer.
With proper impedance matching it‘s by far the cleanest way connecting a Low Output MC cartridge.

Quality transformers don‘t come cheap, and they don‘t come from Ali Express and the like.

E.g. a 2nd hand Ortofon T-30 1st Gen. still is ~ $600, but worth every penny.
It‘s switchable input impedance matches with every MC available, with unmeasurable distortions and not the slightest compromise in FR response.

If these are suited to your cartridge depends on the MC model and it‘s specs.

The Sowter 1480 has a max. transfer ratio of only 1:10, = 20 dB voltage gain.
Typical Low Output MC SUTs have ratios of about 1:50, = 34 dB gain.

This is 14 dB difference and the Sowter is no good match e.g. for a 3 Ohm MC.

So you might not get enough level for a noiseless operation of the RIAA input.

If you want to save and your MC has:
about 2-4 Ohm and,
ca. 0.1 mV or more output, 1000 Hz, 5cm/s,
look for a 2nd hand Ortofon T20.

They go for 200 bucks and share the specs of the famous T30, minus the switchable impedance.

The 3.54cm/s (one channel only) is a different expression of the typical 5 cm/s (left and right channel driven).
Just a different way of measurement.

This way the 0.3 mV (one channel) equals 4.2 mV (both channels).
Factored with x10 from the Sowter 1480 you’d end up with 4.2 mV output, in the lower part of the normal range of what MM pickups offers.

The load impedance the cartridge sees would be 450:Ohm (ADI-2’s input impedance of 47,000 Ohm is transformed with the square of the transformer ratio), unnecessary high.

The Sowter 1990 1:20 transfomer would be a better match:

Output 8.4 mV, cartridge load 113 Ohm.

The 6 dB higher output results in a better S/N ratio.

With it’s widely variable input reference level (gain) ADI-2/4 Pro SE can easily handle the higher input voltage, as my practical experiences showed.

Watch out: the description text for the 1990 primary wiring is wrong:
Primary series connection = 1:10, parallel = 1:20
For 1:20 link grey with red, and orange with white.
For 1:10 link orange with red, and use grey and white for input.

The interconnect cables transformer to ADI-2 should be as short / low capacitance as possible.

BTW: the Ortofon T-20 won’t fit, the T-30 would.
