I had a 50 feet spool of 16 awg copper wire lying around so I made a bi-wire using that.
Overall cable length is little over 11 feet with bare ends on both sides.


Existing jumper had non-copper rings so bare wire should be better.

Listened to few tracks and I think they are cleaner and more open vocals with better instrument separation but that could be my mind playing games.

I'm not jumping terminals again just to check that so it's what it is.
At least now they are bi-wired as suggested.
And keeping eyes for budget bi-wire.
