RF Power Amplifier Efficiency: Big Challenges For Designers
Modern digital modulation techniques demand high amplifier linearity, without which intermodulation distortion occurs that degrades signal quality. Unfortunately, amplifiers perform best when they are driven near their saturation level, after which …

High-resolution audio: Is 2015 the year it takes off?
So on the one hand you believe that sonic differences between MP3's and CD's cannot usually be heard by most people, but in the argument above you do think that 4th (or 5th/6th) order distortion from ultrasonics could be heard within a 20-20K signal?
