<font color='#000000'>I've become curious about this differential amplifier design (for multi-channel amps). This is where each channel has a positive and negative amplifier, so there is no common ground that might cause the hum sometimes found on some amps.
I initially read about this in some literature from ATI, but I was wondering if anyone out there knows of other amps that use this design philosophy? Or if you have any knowledge about this that you might like to pass along? Thanks!</font>
