is there an audible difference bewteen a 250watt and a 350watt plate amp?? if so, on a scale from 1-10, how would you rate the difference??

i've always been told that there isnt much audible difference in 100 watts, but i dont know if thats true...or if that helps you

i've always been told that there isnt much audible difference in 100 watts, but i dont know if thats true...or if that helps youIt's in relation to the starting point ;) If you compare 100 watts to 200 watts you will most certainly hear a difference. With all other factors being equal that is. However 250-350 I dunno. Thats still 40% increase in power, but whether that is an audible increase or not I just couldn't say.

gotta apply atleast twice the power for a gain.

the only difference u willhere is cleaner sound due to the extra hundred..as far as outout i say very little..your ear wont notice it..it may appear to be louder but its actually cleaner

i hope i'm rite

i hope you all are right

thanks all, but i'm now going to be the owner of a 250 watt plate amp from rythmik audio. http://forums.caraudio.com/vb/images/smilies/imdaman.gif thank you, thank youhttp://forums.caraudio.com/vb/images/smilies/imdaman.gif

well as said before, you don't even NEED 1200 watts in the first place. i know of people feeding brahmas 300 watts for home theater.

Doubling your power = increase of 3db (theoretically, without regards to power compression, etc)

So, obviously, going from 100w to 200w should yield an increase of 3db, which is simply "noticeable" (takes an increase of 6db - 10db to be perceived as twice as loud). Take that same 100w increase up in the power scale from, say 1200w to 1300w, and the difference is now so minute it won't be audible at all, netting an increase of only about .3db

The formula is 10*log(P1/P2)

So, 10*log(2/1) = 3db

10*log(1200/750) = 2.04db....which would be noticeable, though not an overwhelming difference

10*log(350/250) = 1.46db...which would be barely noticeable

1db is said to be the smallest increase in output a human can detect.

Pretty much.

But, remember, this all theoretical.

950w may be too much power depending on your enclosure. Power compression may start setting in below 1200w causing less of a noticeable difference between the lower power levels. Etc etc.
