I am using Vampire interconnect OFC cables with rca ends on my secondary sound system; the cables I purchased in the mid 1990s with the braided copper shield visible underneath the clear cable jacket. Given the system's location in a secondary bedroom/office (12' x 14'), I'm content with the equipment. Should I be concerned about these older interconnects noticeably limiting this modest system? If yes, any recommendations or direction would be appreciated. I would need 3 pair of rca interconnects, each pair 2 meters long. My flexible budget is around $700. I'm ok with used cable in good condition.

My equipment is as follows:
Pioneer Elite VSX-80TXV amplifier/receiver
OPPO BDP-83 disc player
HIFIMAN HE400i headphones
Paradigm Titan v5 front speakers
Paradigm Titan v1 rear speakers
Paradigm CC290 v5 center channel
Velodyne CF Series subwoofer

I use the system for home theater (obviously) and listening to classical music (Beethoven, etc.).

Thank you
