External Power Amps will most definitely change the Sound Character of your system compared with just your AV Receiver alone. Like they said, it will boil down to your preference...
Before I was using a Denon 4311 and Emotiva XPA-5 powering my Goldenear speakers...
I find it better sounding using just the Denon 4311 driving my speakers...
Higher power doesn't always mean better sound.
Now I'm using Pioneer Receiver and Rotel Power Amp for my Goldenear speakers...
Before I was just using the Pioneer and find the sound a little too detailed.
And when I added the Rotel into the mix, the sound character become more weighty and musical which I prefer more...
At the end of the day talagang personal preference magdidictate if may advantage or wala ang external power amps most especially when paired with AV receivers...
Mga Gurus,
Pa share naman ng experiences nyo using power amp on your AV Receiver. Aside from boosting the power does it change the character of your AVR? what about sound quality?
Thanks
