I think the various terms are often mixed up / confused in the marketing material of these audiophile components. For me interference is a separate issue to the quality. Especially when it’s something that can be luck of the draw to do with the way your house is wired or interplay between components. It’s also nothing to do with the digital signal itself and the fact it is transmitted via USB ports to eventually show up in the analog signal is a flaw of the standard (transmitters/receivers not isolated electrically) and it can be blocked before the analog stage without making any difference to the source signal at all.
