@OP
I just did a quick google on the m545's ( I don't know which level you are using- Audiophile/Majestic/Ultimate, not that it seems to make a difference in power requirements). All seem to be 50-500 wpc.
So, the MA-1 should have plenty of power- unless you want rock concert levels.
The Sanders and Bricasti seem to be SS amps. Are you interested in SS?
