[QUOTE="Rotelman, post: 801040, member: 19028"] I was referring to the statement Rod Elliot made in the introduction of the article as follows : "[i]You also won't find anything here that suggests or recommends ultra-fast or fast recovery diodes, because there's simply no point for 50Hz or 60Hz mains. Fast diodes are needed in switchmode supplies because they operate at anything from 25kHz up to 100kHz or more. They don't "sound better" than ordinary diodes, and again, only double-blind tests will reveal if anyone can really hear the difference. Remember that the idea of a rectifier and filter is to produce DC which is then used by the electronics. The idea that one rectifier type supposedly sounds 'better' than another is quite silly. There is no evidence that there is the slightest difference to sound quality if fast diodes are used, despite countless unsubstantiated claims.[/i]" I wanted to know if evidence of improved sound quality with these alternatives have been found since 2011, as it is quite an old article and technology-wise alot can change in 6 years.
