How can you be
unhappy with the sound if the sound is great?
Like other members have said, the amplifier isn't making the sound warm or unclear.
It's probably the room acoustics or your stereo preamp is doing some kind of EQ to the sound. Make sure the preamp is in Bypass/Direct/Pure Direct mode to bypass all EQ.
Now if you just don't want Emotiva anymore and want something else, there's nothing wrong with that. And the Anthem STR Integrated Amplifier should sound great if you also bypass all EQ (Direct Modes),assuming your room acoustics is decent.
