I just compared these two amps last week (A-300 Emotiva vs A 51 Parasound (my HT amp))with my paradigm studio 100’s. I played Agnus Obel - Familiar, you really here the difference when she sings the high notes. The A-300 butchered her singing with distortion. My wife couldn’t stand it, and told me to turn it down. When I played it with the Parasound at same volume my wife’s eyes lit up. It sounded so much more clear. That said I could hear no difference in the low and mid range, but I did not play many more songs.
I did not hear the roll-off at high end that people are talking about with Parasound, but then this is the most expensive amp I own. Maybe I’ll here it on my next upgrade.
I’ll be delegating the A-300 amp to my outdoor speakers or selling it.
