The Intona high speed isolator supports USB full speed 12Mbps and high speed 480Mbps and provides galvanic isolation between the USB host and device and protects the device from power shocks and avoid ground loops that can be very troublesome in audio.
It supplies the connected device with 300mA nominal current, 500mA max. This is the industrial version that supports up to 2.5kV signal and power isolation and 15kV ESD protection, specified isolation working voltage, extended temperature grade, high retention connectors.

The Hifime $29 isolator supports only USB Full Speed mode (12Mbps) that are used by stereo DACs that support max 96kHz/24bit.
The $99 High-speed isolator is similar in function to this isolator, but they use different technologies to perform the isolation. The Hifime high speed isolator supports most hi-speed audio devices but there are some devices with compatibility issues. In those cases it can be worth trying the other technology used by the Intona isolator.
The Intona has a lower noise DC supply for the connected device that can help to further reduce background noise from DACs and sound card.
No. Similar to a USB hub, the isolator is “transparent” to the computer and doesn’t require any driver or configuration in settings.
Yes it works with USB 3.X ports. It will max out at 480Mbps, meaning if you connect a USB3.0 hard drive you will not get transfers at 5Gbps speeds. Audio devices doesn’t need more than 480Mbps, so it will be sufficient. Most devices that require USB galvanic isolation doesn’t require 5gbps.
Yes it supports all USB types, the isolator doesn’t care, it just passed on the data to your computer.
It depends on your DAC, computer and electrical environment. If you have a ground loop then it will be removed by using a USB isolator. Additionally the isolator will clean up the 5V DC from your computers USB port. Some computers have very noisy USB power, while other are not so noisy, so the difference will depend on the starting point.
It will fix noises that are caused by ground loops, often presented as whining, buzz or loud shh noises. However some noises are have other causes. For example the microphone preamp might be noisy by itself, or an electric guitar might pick up noise in the air from other equipment. For those noises USB isolation and better quality, low noise DC power will probably not help much.
