Speaker Jumper/Link Cables - Best Ones? Nordost Valhalla, Tara Labs Omega Evolution OR..

I am researching maybe buying two pairs of used 'high end' speaker jumper cables.

My 1990's floor standing tower speakers are Definitive Technology BP2000's.
Each is bipolar so it has 2 woofers and 1 tweeter, both front and back.
Plus each speaker has a built-in 15", 300W sub-woofer.  They can shake the room! 

Main preferred jumper cable sound characteristics: detailed, warm and neutral.
Main music listened to in no order: rock, pop, folk, jazz, soundtracks and reggae.
Main format played: Vinyl - Stereo - 12" LPs and singles, plus 7" singles.

The maximum dream total budget for the used cables is say $1,000 - $2,000 (!)
Hey, it is a dream that maybe be worth auditioning....then again, if there is a used  or new cable that delivers for less great.  Most of my equipment is used 'high end.'

Please do you have any experience and recommendation(s)?  Thank you! :-)
