It would seem that any magnepan speaker with a fuse and a seperate hipass / lopass crossover WILL be biamp able. Even if you must DIY.
My panels, the 1.6 has a lo pass for the bass and hi pass for mid/tweet. So, even if their were only a single set of terminals, It's still likely that anyone with a little DIY in 'em would be able to make the necessary changes.
The 'simple' test for common ground amp would be to turn off and unplug. Let it sit for an hour, just for safety to discharge any of the big caps. Check speaker ground to ground with an ohm meter. Should be zero from both speaker grounds.
I'd be careful with ANY amp these days.
