2nd post. I guess I was away too long.
Heres another way to look at it. How much extra power do you get from the extra 100 watts?
According to this online
Calculator which can only be used as a guide because it doesn't factor in a room and other variables, you can play pretty loud with just 100 watts on my M60 speakers at a listening distance of 3 meters.
As a reference, movie theaters often start 80 - 85 db average listening levels but can have peaks much higher. Again using my speakers sensitivity (cause I dont know yours), lets run some numbers.
A pretty moderate 75 db plus 15db headroom = 90db peaks. This uses only 5 watts.
(Loud peaks but comfortable even for your Mom to listen to.)
80 + a safer 20db of headroom =100db = 45 watts (100 db is fairly loud)
Lets use your 100 watts as a guide. In my scenario, we max out our capacity at a top end of
103 db using 90 watts. because just 1 more db....
104 db uses 113 watts
Now lets find out what another 100 watts will give you...
Just one more db, 105 takes you to 143 watts
Just two more db, 106 takes you to 180 watts.
Just three more db, 107 takes you to 226 watts.
In short, adding 100 extra watts will only give you an extra 3 db of clean & safe loudness.
If your all about loud, this noticeable but fairly small increase might be worth wile for you. I want to upgrade someday also to get more headroom but I'm holding off until I can go BIG!!!!!!
