A20h adopts a very novel circuit design, ultra-low distortion precision linear feedback circuit (PLFC), and the distortion is as low as 0.00008%! Ultra low noise power supply design, so that the output noise is as low as 1.3uV (measured value of APX555B, not equivalent!) Ultra compact design, very suitable for desktop headset system;

Good features but ...
*NOTE* I have only tested this amp with single ended (unbalanced) AKG headphones and some cheaper Panasonic ones.The amp is well built and with the remote control operates smoothly and easily and it sounds great with no discernable distortion.This is just as well because even on the highest gain the AKG headphones aren't driven well and the Panasonic's only just.The amp is just not powerful enough.
