Contrast/compare Magneplanar 20 vs Sanders 10c ESL

Has anyone heard both and if so could they contrast/compare/opine on these speakers?

I have Maggie 20s and thus am familiar with their sound; hearing the Sanders speakers is problematic

I am most internested in

Bass performance
Three dimensionalty
Might sound like the real thing occasionally

Why is hearing the Sanders problematic? Roger has a 30 day in-home trial, with freight covered both ways. It couldn't be any easier. . .
