600 watt speakers

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).

😊 …. Funny man.

Power rating is of no value in comparing speakers. First it is pretty arbitrary and well, of no value. The sound quality of speakers is what matters. I would glance at the efficiency just to make sure it is not on the extremes… say < 86 or > 95, otherwise ignor that.

Sonus Faber are very musical speakers… I own these… Focal are a more personal choice that have a hotter high frequency… which adds detail… but must be carefully paired with electronics.
