<div>As you may know, level handling is one of those slippery specs. The number depends on many things, in order of relative importance:</div>
<div>FREQUENCY, Distortion criteria (at 3% or 1% or ?, and source impedance. Be sure you're comparing apples to apples.</div>

<div>Actually, during my days there, we made the -8M version of the -6M part ... it had a bigger core. The PC mount version ended up with a core size between the two.</div>
