In my opinion, cables is the last in the chain where you already maxed out everything and nowhere else to improve. It could be very little or substantial, and depends on the build, dedication that goes into it. A high end cables is not only about the wires materials and fancy words salad. It is about the synergies, the choices to improve the systems between personal preferences, gears being used.
I am making a new cables that is better than stock. Better in performances, enough to compromises the tank like and superb Build quality of stock cables that minimize microphonic to the least.
Atleast I am tuning it to my liking, so the choices of each components will reflect that. I could explain it all as of why....but I ain’t selling it...the job is reserved for people who make money from cables
. At the prices that they charge, the least they can do is to personalize and choose “components, to synergize with personal preferences and systems”. But feel free to pay in and buy for universal tuning. Because upgraded cables do bring upgraded performances and is very real to my experiences.
Did I already show you all that firmwares and synergies is so important ? Yes...so does Cables, System, constructions, and the Buds that it is hooked up to.
The only different view is that at this expensive cost and charge, it should be more personal and catered toward dedication instead of Universal. For example, an AK SP2K SS sound different than Copper, given if it is firmware differences or hardware, the differences are there...and even more so when compare to Walkman.
Therefore a cables for IER-Z1R that is catered toward SP2K SS has to be different from Copper and or Walkman 1A and 1Z..unless specified by the user....it should not be universal
anyways, feel free to buy universal because at least with Walkman , you have planetary to choose your own poison
And I should stop preaching ...
