My Beam mode focuses the sound at a specific listening position, so the listener can hear all program audio clearly, including dialog, without disturbing others in the room.
That amplifier puts out some very clean sound when paired with non-powered speakers, but this is the kind of setup intended for audiophiles looking for a simple secondary system -- exactly the kind of listener who cringes at the thought of lossy, compressed streaming audio.
I'm a finicky listener with high-end speakers, and found that RadioWave's audio quality is considerably better than standard RealAudio, and lacks the trademark "jittery" sound that's become familiar to Internet listeners.
