Schottky diodes switch very fast. That is an advantage for low loss if you have to switch high speed signals. In mains rectification that is no advantage at all. In fact, the fast switching is a disadvantage because the switch-off current cut-off generates lots of hf signal bursts that get into the supply and can muddle the audio.

FRDs (Fast Recovery Diodes) The structure and function of fast recovery diodes (FRDs) are the same as those of rectifier diodes. Rectifier diodes are used for low-frequency applications below 500 Hz, whereas FRDs are used for high-frequency switching from a few kHz to 100 kHz.

Fast recovery diodes are used in high- frequency switching up to 100 kHz. When voltage is applied in a reverse direction, the diode does not withstand voltage until it enters reverse bias. In reverse bias conditions, the current flow for a specific time. This time is known as reverse recovery time (T RR ).

schottky vs. soft/fast recovery diodes | diyAudio

As a slow diode recovers it will "snap" the reverse recovery current off suddenly, causing the transformer winding to ring somewhat. Fast, ultrafast and schottky diodes (and vacuum tube rectifiers for that matter) turn off more cleanly and don't "twang" the transformer winding and generate noise in the process.
