Re: You're assuming a perfect DAC

Galvanic isolation is a step in the right direction - however its only providing perffect isolation at DC. Check the interwinding capacitance of your S/PDIF transformer - the ones with the best isolation sport a figure <1pF. If yours is higher you still might gain improvement in fitting a CM choke to your cable (or clamping on a ferrite). Also check to see if internally there's a dedicated ground wire going to the digital input termination (75ohms) from the mains trafo secondary. A lot of DACs just use their internal groundplane to carry the CM noise current, impacting the sensitive analog circuits using that groundplane as their 0V reference.

'I currently know of no way for a digital cable to make an audible difference'.

Too long for a title, but perhaps in the text. We agonize over titles because they must be short, yet have enough info to get you to read.

How about a question with the same word count - 'Can digital cables be audibly different?' ?

NEXT UPCOMING BROADCAST

Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
