KGUSS Topping HS02 USB2.0 Audio Isolator is bestand tegen tot 1500 VDC, USB-B- en type C-ingang, USB-A- en Type-C-uitgang, compatibel met PCM32bit 768kHz DSD512

Hub con aislamiento galvánico para aislar tu dispositivo de audio (como por ejemplo un DAC) del PC. Este hub aisla completamente el ruido electrico que las computadoras producen hacia tu dispositivo de audio.Indispensable para equipos de audio y DAC's de alta calidad.

Excellent isolation. This instantly quieted my RME Fireface UCX ii down to complete silence. It’s wonderful, and worth every penny IMO.Build quality seems great too, and it’s much smaller than I was expecting (which is great).

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.

Avevo di problemi di ground loop quando collegavo un programmatore ISP ad una scheda, come suggeriva la stessa Microchip nei datasheet dei proprio programmatori, mediante questo oggetto il problema è scomparso

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.
