The output is 2.8 mV, but that has little-to-nothing to do with sound quality. If anything, lower output carts (moving coil) have less mass to move which allows them to track the better and bring out more detail. The question is whether your phono stage has enough gain to work with this cart. What are you using for a phono preamp?
The 20XH is smoother than the Sonata and I think it sounds better. Give it a try.
