I had a bad hum that I couldn’t track down, so I ordered this. While in transit, I reconnected the pins on the cartridge (that I had just replaced) and that eliminated the hum. When this arrived, I plugged it in just for an added layer of protection and the hum had returned. Removing this component removed the hum. YMMV. You have been warned.

The hum on the subwoofers was not reduced at all by this filter.

I purchased to help with a hum I am getting from my turntable to my receiver. I still have the hum, not sure if it's something else.

I used this filter between my VPI Scoutmaster and my Ming Da Phone Pre. Wow! Exceeded my expectations. I had some hum without it but can now push the volume up while the filter pushes the noise floor down. Bass is still voluptuous and full. I played a track I’m very familiar with and without and didn’t detect any major drawbacks. If I were to offer one small suggestion, make the same filter with a version with both RCA Female In and RCA Female Out (No wired to or from). That would allow the user to control the quality of interconnects in and out of the filter. Overall score ☀️☀️☀️☀️☀️for performance to price ratio.

This review is for the WisWinDa RCA Noise Filter Hum Eliminator Ground Loop Isolator (the one with two channels). I had added a new-to-me high quality DAC and transport to my system, and noticed a pronounced hum in the line added. My other lines did not have this hum. I powered down, added this Hum Eliminator to the new line, powered up, and presto! the hum totally vanished. Gonzo! Good riddance! Amazing how this little $30 gadget can "rescue" an audio system worth many thousands!

I don’t write reviews. But this thing worked so well I had to. I’m the process of a custom car audio installation I was getting an extraordinarily loud electrical buzz through the external input on a secondary head unit. When I say loud, I mean LOUD! The reason was due to the routing of the RCA cables and their proximity to the cars wiring harnesses in the vehicle. I was skeptical that this unit would be able to resolve such a massive interference. But it did. It eliminated 100% of the noise out. I could not be happier with the performance of this unit.

Good product, KRK speakers have a terrible hum when connected to AUS power supplies. Adding this emanated it. Doesn't sounds like it was a cost of any audio quality too.
