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

I am using a Tavish Design Adagio with a Soundsmith Carmen II cartridge with an output voltage of  2.12mv ,  the MM ( MI ) gain is 44db . 

I was unsure if the gain was enough when I switched from a Grado with an output of 5mv since I am going thru a passive attenuator .  If you think that 44db is not enough I believe that Manley makes a phono pre that is adjustable up to 50db .

@mdrone  : Thank's. According the real time measurements made by J.Atkinson in theory the true gain is a little over 37db so you don't have to have a problem running  your cartridge other that maybe a higher than normal noise levels but the critical issue with your unit is that its RIAA accuracy is really poor and goes against the quality levels that your cartridge can shows:

Paradox phono-30 amplification is done via a pair of LSK170 JFET to providing 30dB gain and an external plug for loading your cartridge with any value resistor.

 

You would need a head-amp with flexible loading and gain options. The Hagerman Piccolo is perfect for this, and not too expensive either. The only potential hang-up is it lacks capacitive loading options, though technically you can play with cables for this. 

What is the gain of the line stage that you are using? You should add that to the 28db gain of the phono stage!
