Then I saw this promising looking Isolator USB to USB Optocoupler Isolation Module Coupled Protection Board ADUM3160 Isolation Voltage 2500V board for around 10 Euros.ġ2 Mbps support USB 1.5 Mbps at low speed and full speed does not support pure high-speed equipment I have thought of getting USB isolator for some time, but many of them seem to be quite expensive (many cost nearly 100 Euros). The USB isolators effect a potential decoupling of all USB connections and separate the ‘normal’ PC system from the critical application. It will also protect the USB device and host from electrical shocks or static electricity shocks.
USB isolation works by creating a new ground for the USB device so that it doesn’t have to share ground with your computer (and other devices that you might have connected in your house). USB isolators are the professional tools to avoid and fight ground loops and equalizing currents and to protect against overvoltage. USB isolators are used in applications where direct USB connection can create noise (ground loop noise to audio or measurement), direct connection can be unreliable (noise to USB signal) or where isolation is needed to protect USB port or for electrical safety (for example laboratory measurement).
If you can't measure a problem that you hear, you simply have not invented the right way to measure it.The USB isolator is a device that will pass USB signal from input to output connector, while providing galvanic isolation between them. Thinking like this is how companies like Yamaha produced, for example, power amps with near perfect measurements that sounded absolutely terrible. Refusing to hear what you cannot measure does not make a problem non-existent. Computers, and indeed the USB/wifi interfaces themselves, produce prodigious amounts of noise that is inflicted upon the supply rails & grounds, and properly cleaning up these lines reduces jitter(timing jitter and that caused by spdif waveform distortions), and thus improves the sound from the connected dac. Whether or not one can measure the difference, myself & others I know, and many more I don't, reliably in a/b testing, even blind testing, hear differences when even a single capacitor is changed on even the 5V main supply line of the interface. I can tell you from ACTUAL LISTENING that power supply & ground quality absolutely affect the sound of a dac that's connected to the usb interface, or even to a wifi wireless interface(SB Duet, etc.). Sonic, you really should not give opinions about that which you have little experience.
