The voltage gain on the Emotiva is like 37dB, compared to most amps @ 28dB. To be fair, you will need to crank the speaker channel levels DOWN to match your previous volume level.
The louder volume (even 1dB) will usually appear to sound better, faster, more accurate for some strange reasons.
Or you could try to use the AVR by itself, but this time increase the speaker channel level to +6dB and see if the AVR by itself sounds better, more accurate, faster, etc.
