More and more audio devices are equipped with external power supply like switch power supply or transformer. As we known, power supply plays an important role in affecting the sound quality of audio devices. Switch power supply is efficient with small-size, but the background noise they generate is as several times as the linear power supply and decrease the sound quality. So using linear power supply to improve audio sound quality is the choice for many audiophiles.
