What is your experience with amp power?

Power has nothing to do with sound quality.  If that were true, then anyone could make a high powered amplifier.  Comments about power and headroom are completely false.  Power has really nothing to do with headroom.  And higher power sounds better at low volume and high volume is another false statement.

@knotscott - is going in the right direction.  I have Vandersteen model Seven speakers 83db driven by 28wpc stereo amp that sounds better than the 220wpc amp and even the 100wpc amps we have.  In theory, no one I know would even think to use a 28wpc amp on the Sevens.  But so far it has outperformed the other amps by a significant margin.

Happy Listening   

To be honest, there are a lot of inaccurate statements in this thread.  I am guessing that only a few people here know design and have experience in building an audio component.  For example, a lesser power amp sound as good as a more powerful power amp.  Everyone is welcome to come to our listening room in Northern New Jersey and have a listen to equipment.  Like I stated, I have a 28WPC amp powering Vandersteen Seven speakers 83db that outperforms amps with 100 to 200wpc, from class A/B, Class D, etc.  Also, Adcom back in the day made a 100wpc and a 200wpc power amplifier.  The 100wpc always sounded better.  It is not that simple to double the output wpc and make a better amp.

Happy Listening.

@mulveling  - yes if you read all of the posts, there are plenty of inaccurate statements regarding power and sound quality.  It is not my opinion but there is plenty of designs that prove this.  As my partner in my company that manufacturers tube components and he has a masters in electrical engineering, I have learned how things work and what makes them sound the way they do.  That being said, I am always open to learn something new but the inaccurate statements are based on how an amplifier can be designed and implemented.

Happy Listening.
