Help me pick some new or used speaker cables

For your speakers, Clarity Cables Organic are a great solution.  They have no area of weakness, and will make all other cable sound thin in comparison.  I have very transparent, detailed speakers with authoritative bass in VMPS RM40 BCSE ribbon speakers with all the upgrades except the OXO.  I found out about the Clarity Cables Organic from Doug Schroeder, one of the reviewers from Dagogo Online.  He has been using them for years.  Heard them at his house.  They would be within your budget at the selling price.  I got my 8 ft. pair for about $1500 including 1 ft. long CC Organic jumpers.  After break in, they have been virtually a perfect fit.  They are also open and have very good texture in the lower mids and below.

@rkfaberdds strange the Chapman website specifies the tweeters as silk dome and you’re stating they’re titanium…was this a mod? May be I’m looking at a wrong model?

One important factor to good sound is room acoustics. Room is a component of your system. I don’t see any mention of any room acoustic treatments. If your room is untreated you can’t patch up the brightness with cables. Just keep that in mind.
You might be embarking on a quest for impossible. 
 

My speakers have titanium tweets and mids and my band opened for Zep in 1969, so obviously my opinion is the only one that matters. Ahem...the most recent version of Kimber's 8PR is the best deal out there. Period...no more discussion required...the end.

@rkfaberdds  Have you mentioned which power cables you have? 

I just started using Audio Art cables.  I started with their jumpers and they had a sound , so I bought a pair of their Statement e Series speaker cables and they also made a  positive change in the sound of my system.

All the best.
