What I like in solid core cables is that they giving me the best and coherent bass I heard but at a price of the transparency. Of all three, the most transparent however was the Russian noname solid core AC in-wall cable but it lacks the bass slam and finesse.
Well, as you can see by the myriad of responses, there really is no clear cut recommendation. All cables depend on system synergy and personal musical taste.
However, as you have already noticed, no cable can do it all either. The more transparency a cable gets, the more bass slam (weight) it loses.
Generally, you can either get more speed and resolution, or more musicality and bass weight. Just as one cannot head East and West at the same time, you must make a choice in which direction you wish to head.
Ultimately, sacrifices must be made when choosing the cable that mate best with your gear, to your ears.
