Because doubling the power output only results in a 3db increase ....
1-2-4-8-16-32-64-128-256 (each doubling of power results in 3db increase)
so if going from 64W to 128W results in an increase of only 3db, then going from 105W to 125W would result in < 1db gain. This is also why if you want more power you don't upgrade from a 105W to a 125W AVR, rather you would want to add an external amp that is at least 250W or more, but even then, as noted above, you're still only looking at a 3db increase. In most cases adding an external AVR isn't going to do much more than what the AVR can do itself (unless using 4 ohm speakers, then it's pretty much required for louder volumes).

Nice deal..
