I'm curious about that, too, since Matrix apparently OEM'd the Deckard amp for Audeze.
The only problem would be factoring in the different way balanced amps typically behave vs SE on the same headphone (ie, additional power & greater separation/imaging). One way to do it would be run the M-Stage SE for 1st part of comparison; then balanced for 2nd.
Even that plan isn't perfect since some balanced amps are optimized for balanced output & the SE output doesn't sound quite as good (not sure if the M-Stage is one of those).
