I have been using this model for several years. It’s time to buy a second one. The filter is very good for audio. The sound of high-end equipment is noticeably transformed for the better. But again, I would note that for maximum effect, it is necessary to maintain the correct phase of the mains voltage at the input and output of the filter. I marked the specified phase points with red dots. To the manufacturer for note …
I’ve been using this model for several years. It’s time to buy a second one. The filter is very good for audio. The sound of high-end equipment is changing noticeably and for the better. But again, I note that for maximum effect, it is necessary to observe the correct phase of the mains voltage at the input and output of the filter. I have marked the indicated phase points with red markers. Note to the manufacturer …

Good product. Quality and functionality. After connecting, I felt faster bass and higher treble became more noticeable, softer as if the receiver became a higher class. I was hesitant when ordering but now I’m convinced it works. I recommend it.

what can I say, the quality is extremely high and it definitely benefits the hi-fi system as well as protecting it from dangerous shocks; the audio improvement, if any, remains subjective.

Works excellently, there is a real improvement in image quality and also a sound improvement on my audio; tested with and without this filter, no exaggeration.

While searching, I found out that there is an audio-only power strip, but I’ve never actually used one before, so I’m not sure about its quality.
I bought it because it looked similar, and after receiving it and using it, I found that I’m using an active speaker, and the white noise has reduced significantly, and the sound quality has improved a lot.
It’s gotten better.

Very good network filter. Good quality. Price/performance ratio is right. This is already my second one. Definitely improves the sound of the audio system.
