You can get an idea by looking at the specs for a high quality line level transformer like the Jensen JT-11-BMCF. At signal levels 40 db below saturation, it's still capable of THD + N distortion approaching 0.001%, or 100db further down than that, and this is more than likely noise limited, not a result of a fundamental limit to the core's resolution. A larger core of a similar material would have correspondingly more domains and thus more dynamic range potential.
