Здравствуйте! Сегодня я получил свой Yongzhuxing 600W PFC /LLC @48V, его индуктор и трансформатор издают звук! Были ли посторонние звуки в вашем? Могут ли эти звуки повлиять на качество звука усилителя?

Hi,
Get the Yongzhuxing 600W PFC /LLC @48V or the Mornsun, both are safe value.
The Yongzhuxing has the best performance / price value.

Does that mean that the love story and choice towards "unregulated" PSU is history?

And, trying to digest all Daniboun's projects threads at the same time ;-) did I miss an update about the need and will to test a Micro Audio Unregulated PSU V.S. another brand Regulated PSU with the same Amp Module?

@daniboun I bought LOF550-20B48 and there is an option to use the so called "Remote Sense" function. On the audiophonics website we can read "A 4-pin input for end-of-line voltage compensation (feedback compensation) and its offset are also present. This enables the power supply's output voltage to be self-regulated according to the needs of the powered module, should the voltage delivered suffer losses in the conductors due to the distance between the power supply module and the powered module."
Is the Remote sense function appropriate for this project?

Also was looking out for that but never saw it.
