suggestons on speaker cable that boost mid and upper bass

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.

Stealth V14 works for me.

Thanks pops. I would also like to try Kubala Sosna cables. :-) What's the differences in sounds between KS and PAD in your opinions?    
   
Yesterday when I tried matching different power cords with each components, I found out that a silver power cord of mine plugging to a word clock was the problem.....  When I used a copper power cord on the clock the sounds were much more natural, though I definitely still want more lower mid and upper bass.    
   
Thanks ebm. Stealth V14 is just too expensive to me.  
   
Thanks jmcgrogan2.
