Zitat:Even more impressive is the distortion performance at 1 W output power as shown below. For this measurement a precision 1 kHz oscillator was needed as the 0.0001 % THD of the APx525 source was dominating the THD measurement. The THD at 1 W output power measures to an impressive 0.000067 %, consisting mostly of even order harmonics. This distortion profile is reminiscent of that of a single-ended triode tube amplifier and is commonly considered to be the distortion profile that is the most pleasing to the ear.
