Newish product

Google for "usb galvanic isolation".  I suspect this usb disruptor is just another variation of these galvanic isolation modules.  Nothing new.

Generally, galvanic isolation is used for devices such as laptops.  Their power supplies, when plugged into A/C, are not good and can cause major hum/buzz from 60hz a/c.  This is where galvanic isolators are valuable.  If you don't have this problem, it's better to avoid the isolator modules and focus on a really good USB cable. USB interface is highly dependent on timing of clock signals and you don't want anything in the middle that could cause timing problems or degradation of signals.  If you want to try to improve USB audio, your better off getting a USB reclocker, such as Wyred 4 Sound "Recovery" product.
