Basic question about power/watts

It is called Headroom. Extremely important for my preferred musical experience.

@audiojan nailed it and supplemented by @jmalen123 and in general terms you have to look at solid state power.

TONS of good advice here.  Wow!   So glad that most posters actually understand what is going on here.

While most all are on point, @misstl has a superb post.  The "more info needed" posts are also on point.

As a former dealer who set up MANY pairs of Maggies in MANY types of rooms, please read these posts and CALL YOUR DEALER.  He or she is going to provide the most appropriate help for you since a visit to your room is key.

Best of luck--no box is as accurate as Maggies, so keep working on it.  Hopefully your room will be able to handle them.

Cheers!

As a Maggie owner, I can tell you that 300 watts @ 4 ohms is barely enough.  You will love 400 or more @ 4 ohms.  Provided you have a room to accomodate them.

All too often we focus on only the watts per channel number. There is so much more that make up the power of an amp. One of the best explanations is relating it to a car engine(if you understand cars of course). Cars have torque ratings and horsepower ratings. People like to focus on the hp (watts per channel) numbers snd not the toque (internal power supply). I can give you a car with 1000 Hp that will go zero to sixty in 3 seconds, then I can give you a tractor that will take a day to go zero to sixty but has all the torque to pull a plow and rip tree stumps from the ground. This leads to we’re a compromise has to happen and with stereo amps especially. While watts per channel are the end result you need to see what the quality snd power behind those watts are. Matching speaker efficiency to your amp will influence the end product. If the first watt is not good everyone after it will be bad as well.
