V5 uses 2x LME49713 current-feedback opamps configured as dual-mono audio amplifier. These are ultra-low distortion/noise, ultra high slew rate opamps optimized and fully specified for high-performance, high-output, high-fidelity audio applications.
Below shows a basic diagram of a dual-mono amplifier. In a dual-mono design left and right channels share no internal components. Each have their own dedicated DC power source. This eliminates mutual interference + current sharing between channels hence creates better channel separation. Overall results are better stereo image, improved sonics, lower distortion and noise.
