What is your equipment? Amplifiers are particularly sensitive to upgraded PC. Depending on the components you have, there may be an optimal brand and cost level to realize the maximum potential of your equipment.
In the case of all wires in high fidelity systems what they sound like will depend on your system. So in one system X brand sounds great in another X brand does not sound good.
Also, and for the life of me, I do not know why… but the character of an interconnect tends to be the same as the character of a power cord. Why they would sound similar is completely beyond me. This is just a casual observation by me. Perhaps others have different experiences.
