Yeah this is the main reason to use a USB DAC. I guess you get marginally better sound quality (more noticeable on expensive studio headphones that need more power to drive them) but better isolation/removal from the noise source is the main reason I use them. Especially relevant because in my travel I'm often in countries that don't have ground plugs in their power sources.
