Noise and clock quality are basically immaterial when you're using the USB interface as the transport. This is an asynchronous mechanism - the receiver (i.e. the DAC) will buffer and clock out the data.
Also, I'm not sure why having a technical background is frowned upon. All of these concepts and components were created and advanced by scientists and engineers. In short, audio reproduction wouldn't exist without science.
I'm not part of the 'ASR contingent' as you call it but I do like to see and use evidence (whether it's from measurements or valid listening tests) to make more informed choices when it comes to spending my money. I guess you have a different system.
