Phase Shift is Cool

I just love the phase shift function!! It helps a lot in bring the bass sound to the front soundstage. Previously, i have to invert the polarity to change the phase of my bass. However, it does improve a bit, but my bass is like coming from the mid of my car. With the phase shift from DLS RA amp, i can more fine tune the bass and now my front soundstage is so COMPLETE!
