I recently had someone tell me that adding another amp for my mains and center would result in a noticable difference in sound. He recommended a Emotiva amp....any thoughts?
My thoughts are are you have a terrific system including the sub and AVR.
Your speaker system is one of the more efficient systems available at retail, and it will get very loud and still be dynamic without stressing the AVR you have.
Now having said that it appears you may not be completely satisfied with the sound you are getting.
Please describe what is lacking with the sound and also what your system setup is...
1) Crossover, is it a global crossover or is each speaker different?
2) Subwoofer channel level setting in the AVR, and did you adjust it or the volume control on the sub after you ran the auto cal ?
3) What listening mode do you use ? Auto-surround, direct, some form of DSP mode ?
Fwiw, your AVR was measured by Home Theater and with 7 channels driven with test tones and they got 78 watts, 2 channels driven = 162 watts, and 2 channels @ 4 ohms = 248 watts.
That is beastly performance in a sine wave test. Real world material will never hit multiple channels with max peaks at the same time.
You have much more than enough power to cause more hearing loss.
So I personally see no benefit to adding an amplifier to the system you have for any reason other than you want one. (BTW wanting one is plenty reason to add an amp, but if you need sound quality improvement you need to figure out what is wrong and address it instead of just throwing money at things that will have virtually no effect)
