600 watt speakers

If it is nothing but wattage, an 1,800 watt clothing iron should be one of the best sounding things around....

@erik_squires @mlsstl Is that how you guys get your jollies off by giving a rookie an answer like that? Very strange!

@yogiboy Its not the only way, I'm versatile. Also, @ghdprentice had already given the correct answer, so, in the context of an entire conversation, my "jollies" (Merry Christmas!) postulated such a ridiculous position that would, hopefully, cause the OP to think about his perspective a little.

Yogi boy 

I appreciate you and the two others that gave me some sound advice. I could elaborate a lot more on what I was looking for. The first post that I did I was shocked that it was very professional and helpful. 
I have listened to the Sonus Faber novas. They didn’t have a pair of Amatis g5 that I am interested in. We are trying to set that up so I can listen to them. 
we were using a mc452 am with the 300 watt novas. My question was has anyone heard the amatis g5 which is rated up to 600 watts with a larger amp like the mc901. I have a bit more exp than the guys who answered earlier   I’ve always had high end audio just not up in this arena. I hope this helps. 

OP:  Sorry if I sounded rude, or unhelpful, I only meant to reply in jest.

I do, really, encourage you not to think of your speakers so much by rated wattage so much as by size, and type (dynamic, electrostatic, horn, etc.).

Honestly few of us ever use more than 10 watts while listening to music.  In residential speakers the power rating tends to be little more than bragging rights.

More important are sensitivity, impedance and bass extension which, together with the size of your room could tell us something about whether it could achieve acceptable listening levels for you.
