Your cart is empty. Clean electricity to improve the performance of your audio-video system.
The electricity network in our homes or workplaces is exposed to different interferences for instance electromagnetic interference (EMI) generated by appliances connected to the same network (refrigerators, air conditioners, computers etc.). These interferences are not only produced inside your house or office but by all appliances in your building or even outside it and can differ on the time of day or week when the traffic on the electrical network changes. All these interferences which we call noises can get into your AC power and interfere with your system. This “dirty” electricity can have a negative effect on performance of your audio-video system.
WAudio power noise filter is a great way to limit the negative noises from your electricity and to isolate your system from the contaminated power and has a feature to indicate the correct power phase.
Thanks to the W-3900 you will be able to enjoy a better quality of your audio and video equipment.
The contaminated electricity has also a negative impact on internal circuits and power supplies of your equipment and because the W-3900 works as a buffer between the wall socket and your gear it will help to increase the longevity of connected components.
Removable IEC type power cord gives an option to upgrade your system with a premium audiophile power cable in any time.

I bought this to replace a well used Rocketfish surge protector and outlet distributor 7 years old. Immediately after the install and component connection and power up the same music played at identical volume gain was louder with a wider Soundstage. There was more definition and better focus.All six of my components are plugged into the filtered outlets and l have used the 4 unfiltered outlets for noise suppression plugin devices.The unit itself is impressive in terms of build quality and design.HANDS DOWN A WINNER ACROSS THE BOARD.

Does what it is made to do, and does it extremely well. The unit reduced the electrical socket ground noise from my guitar tube amplifier head to the speaker speaker cabinet to nothing, only hearing the hum of the tubes now. No more annoying and music ruining electric hiss/buzz, only a slight, barely audible tube amp hum. It's delightful. I also plug my Voodoo Lab 2 pedal board power supply into it as well... not sure if it helps with anything, but why not?The unit is built like a tank. Packaged with care from the manufacturer. It has a blue power light that is filtered/dimmed so that it isn't blinding.Fantastic filter/noise conditioner. Highly recommend this thing. It's worth every penny.

Very nice. Still did not remove the 60 cycle noise from the High gain channel of mt guitar amp.

I got this because i was having a terrible hum with my guitar amplifiers. I was running three guitar amplifiers plugged through my pedal board. It took me awhile to figure it out. This AC power filter conditioner was not the ultimate solution to my problem. The solution to my problem was 3 mono passive isolation boxes in the audio lines. But this unit is a very good unit and I am glad I added it to my set up, because running all of the equipment into one electrical outlet through this heavy duty power strip did seem to help some in other ways. This thing is built like a tank.

I have a stereo headphone setup consisting of a separate music streamer, dac and amp. I use this AC Power Purifier for the clean power it puts out. This reduces electronic noise, and my music sounds better.

I like the build quality, however I bought this Power Conditioner to reduce/eliminate noise that is coming thru the AC line. It did reduce it some, but I will need to review what my best option is to eliminate the noise. It did reduce the amount of noise, so I rate this product at 3 stars. I did expect better performance especially at the high price point of this unit.

I’m a professional bassist and have played in many bands over the years - Bought this to try as a rehearsal place our band is currently using has unusually “dirty†power and was causing highLevels of unwanted noise (hum and hiss) through all my basses with active electronics and my Bass Amp head. Took this to rehearsal last night and plugged my system into this - problem solved! Just a little noise / hiss at the very highest levels / volumes when not playing - but at normal levels - quite as a mouse! Won’t go to a gig in the future with out it! I may buy a second one for a back up. Great product that does what it promises for once! Highly recommended!!

Purchased for a fair price , seems fairly well built, time will tell, you never know what’s going to happen from an Asian manufacturer.

There are no CSA, C/UL or UL electrical certification stamps on this 15amp power filter/conditioner.Also, the detachable power cord is only rated for 10 amps.I will be buying something else.

My tube phono preamp easily picks noises and I have isolated it on the filtered side of this device and the noise was removed. I tried to seperate noisy components from critical components in the signal path and it improved my enjoyment of music. I used another strip for tv, router and all noisy things. Im very haapy of this device recommanded.

I loved it so much, I bought another. Blows me away how it just makes everything that you plug into it better. TV, better. Stereo, better. My opinion of the world...better. Power supply, so important.

I thought I'd give this a try since my stereo equipment had a persistent hum at mid-high volume. Really wasn't expecting much of a difference if any at all, but I decided to give it a shot after looking at the reviews here.Plugged it in and my equipment through the conditioned AC:It made a HUGE difference. Virtually zero hum now even at full volume. My recordings from vinyl to tape also have less hiss and better bass.100% recommend this product. If I could, I would give this 6/5 stars.
