[QUOTE="BnGRacing, post: 7600350, member: 557400"] You're probably going to hear the speaker's own distortion before the amp's. The type of distortion you'll hear quickly, and manufacturers do not give a spec for it, is IM distortion. Furthermore, most THD numbers given, if not all, are a-weighted which means that the figure is tested at a high frequency while using low power...usually it's 1 channel driven. The real kicker is if you can hear a difference between two amps, and it's not that hard, you're hearing THD. Some amps sound phenomenal when there's a little clipping going on. Others sound like hell. Most people, and we're talking 9 out of 10 here, prefer a little distortion in their music. It sounds better to the ear despite looking worse on a piece of paper. Listen to electrostatic speakers. To me, they don't sound right...kinda thin. It's just my ears prefer a little 'good dirt' in the music. Don't be surprised if you find you prefer a little distortion too. Go o-scope your amp with 0dB overlap and give it a listen afterward...you'll probably hate it. [/QUOTE]
