Increasing a Low output MM

Hi I have a low output MM cartridge. I am looking at a low gain phono stage; a gift.

Is there anyway to increase the output of a low output MM cartridge?

Previous posts have suggested that a SUT will not work due to impedance changes produced by the SUT.

Any other options, other a new cartridge?

Thanks

The Marcof PPA-1 will work! Battery-powered! I have one for use with low-output mc cartridges. Some Grado cartridges have 1 millivolt or less output.

But I agree it would be nice to know the name of the cartridge: Input impedance would have to be tailored to the cartridge specs.
