I'm a bit confused by which way you want to go. Clarity will go well with bass definition. However, bass slam and bass definition are opposite extremes from all the cords I've heard. I've heard the PAD Dominus cord that Lloydelee21 recommends and I agree it will give great bass slam. However, I would not recommend it as far as clarity and definition go. Clarity and definition you could get from Nordost Valhalla/Brahma or Stealth Dream. These cords will not have as powerful bass slam as the PAD Dominus, Elrod Statement, DCCA Passion Master, etc. Bass slam tends to come from bass being a bit bloated, or slower. Faster, tighter bass, that is better defined bass, many will say sounds lean, not boomy enough for some.
In other words, you cannot have it all. You can look for more clarity and definition OR you can look for more bass slam and musicality. The further you go in one direction the futher you get from the other.
