Linear power supply

Has anyone tried a linear power supply on an Arylic product and have you experienced a favorable difference?

Hi,
The THD+N of the Arylic amplifier (e.g. Infineon Merus class-D) is about 0.1% which is very modest. Replacing a low budget switching power supply with a linear one will be remedial on the wrong side and will not be able to compensate for the weaknesses in the basic concept. Audible differences are mainly achieved by improving or replacing the speakers rather than pimping electronics elements. But faith and hope spread on forums for audiophiles can do a lot…

Greetings
