I understand your question and this is what I can answer.
When I bought my Lumin X1, to help pay for it I sold off a separate Dac, Music server, Digital Clock, Preamp and several other associated pieces of equipment.
With the elimination of that equipment, I was able to then sell the many power cords and interconnects, footers etc. that was no longer needed.
Now the only cables needed was the one set of interconnects to my amps and the power cords for the Lumin and the amps. So, to me, it was important that these cables were of high quality.
With very good negotiating I was able to purchase the better power cords and interconnects.
P. S. Power cords don’t wear out, but may be surpassed by other future "better" versions. Its an ongoing never ending hobby, isn’t it?
