KGUSS Topping HS02 USB2.0 Audio Isolator withstands up to 1500VDC, USB-B and Type-C Input, USB-A and Type-C Output, Compatible with PCM32bit 768kHz DSD512

I have an external audio interface, the Arturia AudiFuse Studio. It uses a USB-C connection and worked great for months until I upgraded the video card on my PC to an Nvidia 4060. Whenever the GPU was under load, the audio interface would screech horribly. This was no ground loop, but EMI coming from the PC, due to the video card creating noise on the PCI bus. I ordered this item hopeful that this would fix the problem and it absolutely worked. My audio interface is deathly quiet when it should be regardless of what the GPU is doing. The only downside to this device is its price, but I refuse to lower my review because it works perfectly.

I have a spectrum analyzer hooked up as part of my speaker chain—it’s fed directly from the RCA output of my preamp (the power amps are fed from the XLR output). I was seeing noise occur on the spectrum analyzer whenever the streamer was busy or loaded (such as when scrolling long playlists and such). I read some of the other reviews stating that this device eliminated the noise they were seeing from their sources (usually PCs set up as streamers), so I figured I’d get one and give it a try. It came in, I hooked it up between my streamer and my DAC, and fired it up. Well golly-gee-Willy, it really worked! Zero noise showing up on my spectrum analyzer no matter how crazy I got on the streamer controls! To make sure I wasn’t crazy, I removed it and the noise came back, so this thing legitimately eliminated electronic noise from passing to the DAC from the source!

*** I have some KRK Rokit 5s on my main computer at home being fed by a Behringer mixer. I didn't know if the noise (low but incessant) coming from the speakers was caused by a complicated KVM switch setup I have, my monitor, my mixer, bundling cables too close to power or what. ** But I finally noticed that unplugging my computer from the Behringer made the problem go away, but my mixer is my sound card if you will and I need it. ** So last week I finally had enough and did some searching on YouTube to find some good search terms, like you, and I found this product. It is AMAZING THAT IT WORKS! ** And it's TINY. You can let it hang from a USB cable if you need to, no problem. ** It comes with a USB cable to plug into the input side of the device as well.

I had some really bad buzzing noises coming out of my studio monitors due to EMI from my GPU (I could literally hear the buzzing get louder whenever I opened a window or moved my mouse around lol). This worked perfectly to fix the problem I was having. No more noise!

This USB Isolator did nothing to fix the audio cracks/pops that i have when trying to use a USB DAC connected to a 2023 Samsung QN90C 43in Tizen tv. DAC is a Qudelix 5K.Tried every combination of cables, powered and un-powered mode, ports, various usb power adapters etc.DAC works fine with no such issues on everything else i use it via usb on, PC, MAC, iphone/ipad.Either this kind of of device does nothing, or it be something with the TV and its usb audio output, drivers, SOC etc... i not sure. I also connected this device in line between my PC and DAC, I have a few other DACS, and noticed no change whatsoever, even with no sound playing, and max volume, to hear any noise/hum/squeal etc. nothing. Though, this device did cause my Fosi Audio Q4 to have a loud constant pulsating popping noise and did not allow audio to work, though the PC did recognize the DAC still.At this point, it is just a expensive usb switch. (since u can select what output is active)

No more static or weird noises from my USB DAC, this absolutely worked! I'm taking off a star because the provided USB A to B cable was bad, it did not work. Had to use my own USB cables. Otherwise, I am very happy with this!

Digitally transparent, your PC or Mac won't even know this is there. I had the Intona Isolator, the pricier one not the cheapest one and it broke some of my DAC's ability to go over 24/96k. This works with all of my DAC's and allows full use of the resolutions on offer (including MQA and DSD).You may feel like it makes no difference if you didn't have "hum" or "buzz" or "noise" but if your DAC isn't galvanically isolated then this does make a difference. I notice because my powered speakers when set to full volume connected to my DAC as a preamp would hiss or have static. This was only at or near full volume. If I disconnected my DAC from my PC's USB and instead connected it to my phones USB (battery powered) the noise went away.In other words dirty power PC noise over USB was making it through. When I used my DAC to my headphone amp and headphones this was never audible. All the same once I put this between my PC and DAC the noise was gone and when using headphones it was even cleaner sounding with better spacial detail. I recommend these. Especially given how cheap they are. Though it's true, whether you notice the improvement or not will be system dependent but it definitely DOES do what it claims.

It passed power but does not pass data. I tried it with different devices and different configurations and none of it worked.

I was dealing with GPU noise from my NVIDIA RTX 3060 12GB when a game was running with both my iFi Zen Air DAC and also my Topping DX3 Pro+. The reason is because my headphone amp is a valve/tube amp so it must be earthed due to the very high voltages, and this meant there was a ground loop with the noise from my PC. I tried the usual tricks of putting everything on the same extension lead, which while it did reduce the noise, it did not eliminate it and that was problematic when using my Beyerdynamic DT990 Edition 600 Ohm headphones.So I went ahead and got this USB isolator since it supports USB 2.0 hi-speed (so it should actually handle above PCM768 @ 32-bit and DSD512/48 without issues, but I do not have a DAC capable of going higher to test). While it was working, and the computer noise was ENTIRELY eliminated, I was getting random and very often cutouts from the audio. Windows and Audirvana could still 'see' the DAC, just that the audio stream was getting cut off for some reason. This was plugged into one of the USB 3.0 ports (*just* 3.0, not Gen 1 or higher). I decided to try plugging it into a USB 2.0 port as I do know there can be compatibility issues with 3.0 ports, and I also shortened the cable to 1.5m. This totally fixed the issue I was having, and now I can easily send PCM768/DSD512 to the Topping without any dropouts of any kind. The iFi also handles DSD256 without any issue too.Even new motherboards released today have USB 2.0 ports specifically because 3.0 (and higher) can't always handle 2.0 devices correctly, and after reading the datasheet for the USB isolator chip they're using, it is very specifically for 1.0, 1.1 and 2.0, and requires incredible precision on the circuit layout to work correctly - this is one reason why this is expensive.So it gets 5 stars because not only did it entirely eliminate the GPU noise, but the big improvement in the noise floor seems to have given the valve/tube amp a bit more room to breathe, as I noticed a subtle improvement in the attack of synthesizer sounds. Your mileage will vary here obviously, such as how well trained your ears are, what gear you're using and what audio format you're using.

Ho acquistato il TOPPING HS02 dopo avere provato altri due isolatori , uno economico e l'altro più costoso (dei quali ho pubblicato la recensione) che non hanno funzionato.Quando questo è arrivato temevo di ricevere la stessa delusione avuta in precedenza. Invece NO!Prima di collegarlo ho verificato che l'entrata e l'uscita fossero realmente isolati. Erano assolutamente isolati.Appena collegata al mio Steinberg UR22 MKII (con una alimentazione ausiliaria) l'interfaccia audio è stata immediatamente riconosciuta e ogni disturbo nel mio sistema audio è sparito.L'isolamento galvanico ha funzionato alla grande.Ora è tutto OK. Il mio impianto suona benissimo senza alcun disturbo.Se avete dei disturbi come i miei, (scariche udibili anche durante lo spostamento del mouse o durante l'accesso alle memorie di massa) potete usare questo strumento che li elimina totalmente.L'unico rimedio per questo tipo di problemi è l'isolamento galvanico.Non servono "filtri miracolosi" o altri espedienti inutili.Spero di essere stato utile.

Ich wollte es einfach wissen bzw. selbst hören, ob man damit eine klangliche Verbesserung erzielen kann.In meinem Fall: eindeutig ja!Datenquelle ist ein günstiger, (insbesondere bzgl. Netzteil) weit von High End entfernter Android Medienplayer, auf dem mit UAPP eine spezielle App läuft, die für die sogenannte "bitgenaue" USB-Übertragung der Audiodaten sorgt (Betriebssysteme wie Windows und Android sind diesbzgl nur bedingt echtzeitfähig - spezielle Treiber sorgen hier für Abhilfe).So betrachtet eigentlich alles bestens, denn USB ist eine (auch bzgl. Software/Treiber) etablierte, genormte Schnittstelle, die benötigte Datenrate i.d.R. geradezu lächerlich. Datenfehler/Paketausfälle sind in nicht-industrieller Umgebung bei kurzer Verbindung und halbwegs vernünftigem Kabel praktisch ausgeschlossen. Allerdings könnte sich die bedrahtete Verbindung zwischen Quelle und Senke auswirken...Lange Rede, kurzer Sinn, ich bilde mir eine sofort und deutlich hörbare Verbesserung ein. Gemessen an den Gesamtkosten der Anlage ist der abgerufene Preis mehr als moderat. Ausprobieren verschafft Klarheit und ein Rückgaberecht gibt's ja auch noch.P.S. Alternativ hatte ich noch den Ifi iPurifier 3 getestet. Keine Veränderung der Klangqualität zu bemerken. Ging wieder zurück.

ゲーム起動中などグラボに高負荷かかかるタイミングで外付けのUSBADC経由でジーーーというノイズがスピーカーから聞こえる問題にずっと悩まされていました。原因を切り分けて調査したところ、どうやらUSB信号にノイズが重畳しているということまではわかったのですが、どうやって対策しようかと調べていたところこの製品を見つけました。若干お値段が張るので躊躇していたのですが、レビューの中にグラボ経由のノイズが取れると書いてあるのを見つけ購入に踏み切りました。注文してすぐ届いたのでPCとDACとの間に入れたところずっと悩まされてきたノイズがピタっと止まりました。価格相応の効果を得られ非常に満足しています。
