Power Cable with a "soft" top end


OK without getting into a war about whether a PC does enough to change a system's sound or about using cables as tone controls can folks list any cords Sub $500 that traditionally considered soft/warm on top. Im one who does not believe that euphony and midrange emphasis is bad thing. Particularly b/c i listen a lot of poor sounding live recordings....thanks in advance.

Thank you everyone for the replies and suggestions. I initially did not list my equip because i just wanted some generic recommendations. I am seeking a cord for use with my joule pre amp. Used or new.

In any event as a follow up, i have no objection to purchasing used. The reason for my inquiry is that I have a very very bright room and live in an apt. in nyc with children. So i have no/zero ability to adjust the room. In addition to the walls, a large picture window behind and to left of the listening position does not help. In other words if i was in the burbs, id be exploring room treatment. With that said, recently swapped out my basic signal cable power cord to my preamp with a higher end silver based cord. The differences were quire remarkable. The detail, transparency bass and depth increases were huge.

However, the downsides to the cord swap was that it added too much to the top end and does not make the music relaxing. So i love the change but my body and and ears would be dreading certain vocals.

The system is as a follows,

Bolder Digital Modded SB3 with modded Elpac PS & ERS Cloth>Signal Cable Digital Coax or VH Audio Pulsar>
John Wright modded Meitner/Museatex Bitstream Dac & Iego PC>Updated Audio Magic Stealth Matrix Mini
Joule Electra LA 100MK2>Reality Cables IC
RWA Sig 30.2 or Joule Electra Stargate Monoblocks>Reality Cable Speaker Cable> Omega Super Three Narrow Hemp on Skylan Stands, TBI subwoofer

Try Cardas Golden Ref, it carries the same sound signature to all line of Golden Ref.
For what it's worth, since I've never had any DCCA cord in my system, but I keep reading they're excellent.

I have several DCCA and Don makes great cords, can tweak them to suit your sonic needs (softer top end) and is a delight to work with....
