Nobody suggests taking the amplifier off the speaker?

I'm assuming he's more about collecting than listening.

The M22 is doing great and sounds excellent!  I actually just acquired an M-25 as well, it's really nice with the Gold plated input/outputs.  Also, it's Class AB so with higher power demand it switches to Class B for 120W output and cooler operation.  Love them both!  Also, no issues with the amp sitting on the speaker, these HPM"s are very stable with little to no vibration, previously I ran a Dynaco Tube amp up there with no issues.  Also, I've tried moving the speakers around a bit but i'm in a fairly small area so the sound changes were minimal.
