I can absolutely tell the difference. Running a lot of audio equipment and also ham radio. Takes a lot of the subtle hums and fluctuations out of the mix. Really glad I purchased

Just What I was looking for!!When I came across this WAudio unit I was very excited as I have used this brand before and found it to be very beneficial in my Audio System. This is a very nice shelf standing unit, as opposed to the "on floor" model blocks they also sell. To me this type of model sets up for a cleaner all around setup being your power cords aren't running to the floor.The unit is very nice with plenty of "Filtered" and "Direct" outlets on the back to fit your needs. I am now loving the fact that not only are my DAC's and other equipment getting "clean" power to them, but I also noticed a difference in the low end punch of my system with this unit, just like I have experienced with their floor models.The VU meter showing where your particular power is at the moment is a very nice addition to this unit. I also now have the ability with one switch on the front panel to cut power to all of my equipment when not in use. This in itself is also a very nice feature of this unit.I can gladly recommend this Power Conditioner to anyone looking for this type of unit to ensure their electronics are getting what they need and are also protecting them at the same time!!BubbaCheers!!

Aesthetically, the item looks awesome in my AV rack with its sleek metal design and cool voltage meter. This conditioner also provides many outlets for use, which is convenient. But, that's where the good news ends in my opinion.This item did nothing to noticeably and/or clearly improve sound quality or sound stage. I did a before and after test and neither lossless music nor movies sounded any better/different on my SVS Prime Pinnacles. People have to understand these AC power filters and aftermarket "audiophile" power cords are pretty much snake oil. Most any decent AV receiver or amplifier will already have EMI dampening properties built into their circuitry - one doesn't necessarily need a $250+ dollar AC line filter or aftermarket power cords to provide "clean power." That said, if you have cheap or entry level electronics and experience humming or crackling issues with your speakers, then trying out a power conditioner such as this could be beneficial. But for most, power conditioners are likely not necessary. Also, keep in mind, amplifiers and subwoofers with internal amps should not be fed through power conditioners, as doing so could rob them of power and hinder performance.Honestly, save your money and either treat your room acoustically or buy better speakers - these types of improvements will provide you far greater sound than anything like the W5900. That said, if money is no object and you want a cool looking surge protector, then the W5900 is a decent buy. Just don't expect significant audio improvements.UPDATE: 2/21/23 - I wanted to update my impressions after about one year's time and also respond to someone calling out my review. I'll reiterate, my impressions of this product have not changed. The product does not, and has not changed the audio reproduction or quality of my SVS ultras/pinnacles in any discernable way. NOTE: I'm not saying the product does not have the advertised dampening technology within it, I'm merely saying the product has not improved my system's sound quality - big difference.All electronics, especially high quality AVRs, already have EMI dampening properties built into them. A $250 dollar power filtration system (which is pretty cheap, lets be honest) is not going to dramatically improve the audio performance of your existing system - its just not. Such a device may alleviate some minor distortion, humming or "crackling", but again, I never had these issues to begin with, so cant speak to that.My intention is not to bash this product in any way; rather, my intention is to simply offer you my 100% authentic opinion. Of course, we're all different. We all have different equipment, different speakers, different rooms etc. Opinions could and most likely will vary. Though I suspect there is some level of bias involved for those who purchase this product, as many likely "want" to hear the improvement they think they paid for.Now, feel free to heed my opinion, or not. But anyone who makes it their mission to simply call out other reviewers while offering no listening impressions of their own is simply doing prospective buyers a disservice.

I opened this up and verified this is a very high quality power conditioner and protector consisting of a common-mode-choke and RF noise suppression caps. A picture is worth a thousand words. Both pictures prove it's what the seller says it is. But what do I know, I only have degrees in bio medical and electronics engineering. You might want to stray away from that you tube channel.

Looks good does the job , I’m good with that

This is not good quality product and not worth the money I paid.

I really wasn’t expecting much as far as filtering or conditioning, the sound of my system. Boy was I surprised the sound quality of my system actually improved not marginally but noticeably. I don’t know what’s in that box but whatever it is, it’s a game changer. Af far as the packaging it was very well packaged. My only complaint is that there was no literature in the box other than that, it was worth the money.

Just received my power conditioner this evening. I have a large vintage stereo system with a lot of components and easily filled the filtered section and a few on the direct plugs. Listening to some .dsd files I could sense a bit more bass, but was definitely quieter between tracks so that was unexpected. So what’s bad? The POWER LIGHT IS A BLINDING LASER BLUE!! Oh my gosh I’m seeing spots in my eyes! What is the purpose of such a bright blue laser light. Just terrible. I had to recline and put my feet up to block the eye burning laser show. I too have lights on the meter, two super dull blue lights that do nothing to help see the voltage gauge. They should have added some warm white bulbs so it’s possible to see the meter in dim situations, like the old vintage VU meters. So the unit is okay, but I might return it for the power light. I refuse to put a piece of tape over it. These guys should have a lab so they can check the various scenarios that customers may use their products.

I wasn't going to leave a review, I got this mainly to protect my equipment. I'm pretty amazed that it acually made a difference in sound! Not so much with my digital amp but the bass does seem tighter and the center of the soundstage in my stereo system seems a lot better somehow. Where it really made a different is my tube guitar amp though! It sounds quite a bit better and it already sounded good before, it sounds almost smoother or something, and the hiss when I'm not playing is only about a 1/4 of the volume as before. There isn't as much interference with the pedals now either. I have my sound system, subwoofer, record player, pre amp, PC and screens, TV, guitar amp and 10 pedals plugged Into this with no issues and everything running at fairly loud volumes too. The light is not dim.. but it's not as bright as other reviews make it seem I don't think, and where its not going to go on the top shelf, i hope, it shouldn't be an issue. This picture makes it look brighter then it is, I tried to get one that showed what it really looks like but for some reason there's always a glare, it really isn't as bad in person even with the lights off.

In terms of sound, I cannot tell much difference between the two.Big difference is power cables are plugged in from the rear instead of top. So if you place this in a stand or console, you have to go with this.
