suggestons on speaker cable that boost mid and upper bass

Thank you all for your suggestions. Mich appreciated.  For ICs, I am using Stage III Concepts Gryphone from SCAD to preamp and PAD 25th Anniverary from preamp to amp. Both are great ICs. Thats why I think my speaker cables are the weakest link. I am also thinking of copper wires. Anyone has experiences in PAD and Kubala Sosna speaker cables? I heard they have great density and flow and are a bit warm. Interested in PAD Neptune or Kubala Sonsna Emotion or even Elation. A pair of Dominus are just too much when buy new. Been looking for second hand pairs but not available at the moment. How does Cardas Clear Beyond sounds? 

Unfortunately, there is no one "wonder" cable that will do all of what you want it to do. No magic cable will increase body and musical weight without sacrificing the HF and resolution that you love about your connex audio speaker cables.

You cannot go East AND West at the same time. As cables deliver more musical weight and body, it comes at the expense of resolution, and as resolution increases, body decreases.

I have heard Kubala Sosna Emotion and many versions of PAD cables. Yes, they will provide the body and punch that you seek. However, they will not provide the HF and resolution of a silver cable.

You pays yer money, you makes your choices.

I’d return back to my original suggestion; Siltech Royal Signature series. It might be possible to source genuine dealer demo cables at good prices...particularly after CES.

I like Stage III for power cords, only.
Keep me posted & Happy Listening!

Jmcgrogan is absolutely right, his view has been my experience with many cables - it would take a full page to list all the cables I have owned and tried in my system.  Melbguy's suggestion sounds interesting - that is one cable I have not tried.

I have had full looms of PAD and KS.  I had venustus, corvus  IC's and for SC I had proteus provectus.  Had them for a long time (for an audiophile) but over time I found they did not add the body I was seeking with my Thiels.  Currently using KS Fascinations throughout and they seem to be a nice match as Thiels do not need help in the upper frequencies.  Considered Emotion but not sure you get that much more for the huge price difference.  I believe you get more at the frequency extremes but again, do not think I need it in my system.  

If you give KS a shot you probably want to start with Emotions - they have a good audition program and allow trade ups as well.
