BMC M1 vs Audionet AMP or AMP MAX


I wonder if anyone has had a direct comparison or listened to both in separate systems? Both seem highly rated but BMC seems more popular than Audionet. Any reason for that?

And just to add another German amp to the list, the Sovereign Glory. I'm thinking to use one of these to drive the Sonus Faber Cremona M.
Still hoping there will be some ideas from A'goners...

Another set of interesting comparison: Luxman M800A vs MSB M202. Would like to hear opinions on their musicality and neutrality.
