I think the key words are,if used within their power limits.If say you are running your speaker at low to moderate levels then there will be no difference in the sound,at least there shouldn't be.Where it is good to have a seperate amp is when you start to push your AV reciever past what it abilities are.

Most recievers do not have the robust power supply that a typical seperate amp does.If a person is using say a pair of M80s at very high levels is where you would notice the differences.
