Good USED Speaker Cable Choices for $300-$500 ?

With SO MANY Cables out there where do you start?

I am looking to create a warm "Brit" sound that is
polite yet rises to the occasion with punch when
called upon. Maybe a little rounded on the details
in favor of musicality and general warmth. (to me
warmth is the same as saying slightly dark)

My suspects for good (USED) 5-6 foot speaker cables are:

Analysis Plus Oval 9
Purist Audio Aqueous
XLO

What seems to be the best bang for the buck Speaker
Cables out there USED in the $300-$500 price range
which might promote the kind of sound characteristics
I describe??

Thanks..
