Headphoneus Supremus
There are also many people who believe cables have no effect at all on the sound, I will admit that I am one of those people. I would suggest that you simply listen to the Z1R and enjoy it, even with the stock cable it will sound the same. I needed a custom made speaker tap cable to use my NAD M3 amplifier to drive headphones. I have a Norne Solv X cable and despite that I have never once heard with it, or any other special cable the slightest difference in sound.
Somebody once brought over this expensive USB cable for me to test. I use the cheapo USB cables that came with a printer in my system and when going back and forth with whatever this "special USB cable" there was no difference at all and I believe it was a few hundred dollars versus my dollar store variety cable so make of that what you will (or won't).
To each their own and your position is certainly cheaper so great that this works well for you but I absolutely do not agree
