which power cable and USB cable for my Innous Zenith Mk3?

Grunge1000  what does your audio system consist  of ?

if you can’t  hear the difference  in quality. Power cords 

then it’s either the quality of your equipment ,ears or both. 
if it were not so 95+% of all Audiophiles wouldnot be doing it.

@baylinor 

Which DDC do you have?  Next question:  what cable are you running from the DDC to your DAC?.

Thanks!

I have a Zen MK3.  Got a great USB cable from Pine tree Audio online to connect to my DAC.  Picked the length and color.  I got my Ethernet cable to connect to my router from Blue Jeans Cable.  Again made to order length and they test the cable and include the test results.  I suggest contacting Innuos if you’re thinking about changing the power cable.  I believe they have options for  upgrading power sources.

More equipnent info can be seen in my house of stereo system. My entire streaming system is pretty complex and not cheap. But incredibly worth it.

@mihorn  How about stopping with interjecting into every thread no matter the topic your sales pitch of how great your products are. It's annoying to say the least
