Nobody is forcing you to do anything you don’t want to do. Many people find the exercise enjoyable. Are you suggesting that you don’t want to test yourself, you want reviews to tell you the answer (as if there was a single right answer), and that because a review sample isn’t paid for the reviewer should give you a conclusive answer that solves the issue for what you will hear? I’m a bit confused. barrows and asdf1000 2 Founder of Audiophile Style | My Audio Systems Link to comment

The nasty RF Rob always talks about is mains borne RF making its way into the DAC. He describes RF as a fungus... affecting IM distortion. TOSlink is 100% immune of upstream RF. For USB input to be immune of mains RF , there is only one way - battery powered USB source. Eg. mobile phone, laptop with charger disconnected. opticalRendu is great but tricky to make it's PSU 100% isolated from mains RF. Powering with a battery is one way.

They do not isolate the USB input stage itself from what comes before. Just sayin'... They just offer a moat. Founder of Audiophile Style | My Audio Systems Link to comment
