There is no such thing as too much power .
It is a known fact that dynamic transients in music can exceed 10 x
The rated power in milliseconds. This s why by having the extra power the extra headroom is a Big plus.
The amplifier is coasting and not having to go into distortions. I run Maggi
3.6, as well as big Revel speakers with the 550 with no problems whatsoever. in a
16x22ft room .the volume on this is a very high precision ladder type
That goes up to 150 for a lot of flexibility.
