purist vs. concierto vs. elrod vs dcca power cable


I am trying to upgrade my power cables for my system, which consists of first sound MKII preamp, cary MB500 monoblocks, MBL1531 CD player with shunyata hydra 8 and richard gray 1200s power conditioning. I've heard some very positive things about the cords listed above. I am looking for a little extra warmth with exceptional detail and soundstaging, and a bit more bottom end fullness (but not mushiness)--not audiophile terms, I know, but descriptive, I think. What do you all think?

MrTennis' explanation is on point, and very good.

The solution to the OP's desire for a touch more warmth is not with power cords, IMO. The components described are themselves not warm.

At the least, I would suggest some Mullard or Brimar tubes in the First Sound preamplifier.
MRT, are you suggesting any bloom in upper bass and midrange is always matched by a corresponding attenuation of energy in the treble?
gentlemen:

a peak in the upper bass/lower midrange is independent of any other deviations from flat frequency response.
MRT, that's what I thought. And what would you call a PCS displaying such slight flare in the mid/upper-bass frequencies and being otherwise extended/flat elsewhere?
