Others can explain it better; but the reason you hear more is that there is more muscle to move/project the sound. visually its like spreading butter, more butter spread over your toast will taste better than that pat in the middle. I have a EMOTIVA XPA-5, an loving it.It WOKE UP the front stage. RC62, RF82's, an RB81's for heights. I have a WALL of sound and dynamics that still amazes me;JUDGE DREDD: Ohh the surrounds have 150w x4......
LoL What ? This is verging on the head-fi "No double blind test" forum where the wacko audiophiles post.
Headroom is power in reserve or indirectly the volume in reserve that an amp/speaker combo have. Simple as that. If you're running your speakers so that absolute peaks are not clipping, and the speakers are not distorting from reaching max excursion or overheating, then you have headroom.
If your amp's reserves arent tapped dry and causing clipping, adding an external amp and asking it to push out the SAME WATTS as your normal amp aren't going to "put extra butter on your toast". An external amp doesn't give you a cleaner signal unless the original amp is causing distortion at those levels.
At low volumes, it's all in your head, the fact that the external amp has more reserves for loud peaks doesn't matter if they never get used.
To spread this quasi-scientific illogical reasoning is going to cause people to go out and spend a lot of money for things that will not make a difference when they could be adding extra subwoofers or acoustic treatments or nicer chairs or something that really will make a difference.
Also, I'm sorry to come down on your post, I don't wish to offend you on a personal level, I just think your opinion on your upgrades are skewed based on some misunderstanding of electrical components as well as a good chunk of money spent on something that gets a lot of over inflated reviews.
