i am using a sony 100w per channel stereo reciever to power my alesis point sevens and it works great.just be sure that when you are mixing that any tone controls on the amp are set flat or bypassesd,and that any loudness or bass boost switch is off.also,check your impedance.many nearfield monitors are 4 ohm load whereas home equipment is 8 ohm.if your amp has 2 sets of 8 ohm speaker outs,you should be fine as long as you don't run any other speakers at the same time with them.check to see that you don't underpower them.an amp that pushes 20rms paired with speakers rated at 100w rms wouldn't be a good match,whereas 80w would be good.i am sure there is some kind of formula for it somewhere,but i am getting too old to worry about math and just go with what works.the most important thing is that you have nearfield monitors amd not stereo speakers......peace
