Thanks for the suggestions. Currently, strangely, the best are the first generation Shunyata Anacondas-- a VX on the cd player to tame upper mid glare and an original Anaconda Alpha on the amp (a Pinnacle).
This combo produces a pretty relaxed sound and good palpability without thickness and reasonably sweet highs.
A 2nd Anaconda VX on the amp produced a too-muddy undefined bass and loose lower mids, especially on the HD800s.
Stealth Dream cords had superb controlled bass but were just too hyped up in the upper mids and highs.
Some lower price cords from TG and others just didn't have the silky mids and vocals and rounded images and layering I hear from the firehose-thick Shunyatas.
But I ask because I am still looking for a cord that will do it all, meaning a very relaxed sound that never goes "over the top" with upper mids and female vocals even with poorly mastered recordings
but still has a firm grip on things.
Somehow the newer Shunyata offerings, while clearer, a little less "fuzzy" can have a bit of shout that is evident with headphones (less so with speakers).
Sometimes I think a power cord company should offer a cord voiced specifically for headphone listening. I'm actually surprised at the extreme difference these cords make on a headphone system,
eve more so than speaker-based systems.
Just though I would share my findings here and thanks again for the help.
