what amps/subwoofers are you using for Magnepan LRS?

apologies as I've scoured online for specific pairings regarding amp/subwoofer combos and can't seem to find too many within the various threads
I've seen amp recommendations in the form of Hegel h90, Rogue Sphinx and Crown XLS
Sub recommendations seem to be diverse, from what I gather small sealed subs and REL's are popular

what are your proven combos that you use?
