Untitled Document Imagine audio so clear you can hear fingers hitting the frets, the breaths between the lines, and even the spit on the singer's lip. Converting your speakers to Bi-Amp mode is the single most powerful thing you can do to reach that kind of clarity. And this Bi-Amplifier can help you do that.
