no. price, performance (newsflash: sinad several decibels beyond audibility is not the only relevant performance metric for an amplifier), features. it's a poor product with real compromises (poor power, inefficiency, not great with complex loads, not quite small not really big etc etc) made in the name of inaudible "performance". you buy this for bragging rights, so that you can slap a "i don't know what sinad is, so i bought the highest sinad amp" sticker on your forehead, just like most of the audiofool snake oil (except this has pretty graphs)
