When no content is playing, there is a static/white noise

Static noise persists as long as speakers are plugged in and power is on

Crystal clear sound with no pops/hiss/noise.

Cant hear any noise when idle at all.

Very clean sound, no noise or hum.

The amplifier has a hissing white noise when plugged in the speakers without any sound playing

Sounds great, works like a charm...absolutely no noise at normal to higher than normal listening volumes.

The volume control is smooth and it produces very little hiss/noise.
