600 watt speakers

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.

I found Erik’s comment funny. I think in the context of other comments… obviously funny.

OP,

Solid state amp power and tubed amp power are different on speakers. Solid state amps are big on slam… a solid, instantaneous wall of bass… and the more power your solid state amp has, the more pronounced it will be. For either speaker… 100wpc to 1,000 is great (generally the more the better as long as they are the same quality), assuming you are just playing speakers at normal listening levels… like 65 - 90 db. You do not want to be cranking an amp to nearly 100% for no reason… then you must worry about the number of watts you got.

Tube amps (in general) render bass more realistically…nuanced, like you would hear in a concert. Also, not as much power is required…. (Solid state run out of power easily and quickly and sound bad… the instantaneous wall of bass has a downside). I am running a pair of Sonus Faber Amati Traditional (90db efficiency) with a tube amp in triode mode, so 70 wpc. They are capable of undistorted volumes in excess of 95db (at which point I left the room, when I have had a couple different people over here that loved sound pressure levels at deafening volumes).

Just an observation -- I've been online since the Compuserve forums back in the 1980s which predated the "internet" and even AOL. Wisecracks and humor are just a routine part of discussion forums.  Its not something one should take as a personal slight.
