Sennheiser upgraded cable Cardas/Equinox?


I have several pairs of Phones. Senn 650's. Grado 325i, AKG 501's All of which I use with my ASL MG DT OTL MKIII HP amp.( tube rolled to good effect and AC cord replaced with Synergistic Research Master coupler)) and using RS Audio Illume' and Audio Art IC-3 as my HP amps connects)
Im looking to upgrade the cable on my Sennheiser 650's. I have tried the Moon Silver Dragon to good effect, but I still feel that even as good as this cable is... and its very good..( deep bass and dynamic midrange )I have a few issues with a lack of resolution and what I would call a "slight lack of tonal quality" in the upper mids.Not bad mind you..but I feel that I can get better still with perhaps the right cable upgrade. Not to mention how stiff and awkward this cable tends to be. I have not tried the Cardas or the Equinox cables, but am thinking of the Equinox...dont know where to find them however.

Can anyone offer an opinion or suggestion? BTW...Of course Id love to have the Stax Omega or Senn Orphius systems...but Im living in the real world with HP's :)

Thanks,
Ken

The Zu Mobius cable for the 650s is natural, neutral, and balanced sounding; it's very relaxed & smooth & not bright. (Brightness is something to be avoided at all costs with phones, IMHO.) It is much better than the Cardas (I have both.)

Physically, it's a bit stiff, so be sure it's long enough (mine is 10-feet, or maybe 3 meters).

I have not tried the Equinox.
Thanks. I agree with you on the brightness issue with phones. I can live with less than the best bass...but the highs have to be smooth! So..where can I find the Zu Mobius?
i just returned my cardas sennheiser cable - it was terrible. better than stock but nowhere close to zu mobius and silver dragon in terms of transparency and speed.
i prefer silver dragon to zu mobius - cheaper, better speed and transparency.
i have never tried the equinox.
equinox can be found at todd the vinyl junkie and dedicated audio, send zu cable an email if you want to buy the zu mobius.
