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

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.
Tiberian- Thanks for the info. Both you and Rgs92 are of the same opinion on the Cardas. This was very timely and helped me avoid getting the wrong cable for the Senn's.

Like you, I did indeed like the Silver Dragon, but sold it( typical audiophool impulse here). I just ordered the Blue Dragon from Moon Audio. Based on the reviews and Drews own assesment of the sound of these cables, The Blue is very similar to the Silver in sonic balance with a touch less detail in the upper mids and highs. That sounds like the cable Im looking for, and at the length I need (17ft) much less expensive than the Zu would be.

Thank you and Rgs92 for the very nice, helpful on and off line information!- Best Ken
please tell us your impression once you get the new blue dragon :). personally i am trying to avoid copper in my signal path.
Tiberian- Will do. This may be the only area where I want copper. All my IC's and PC's are silver! Ill be sure to follow up.Drew is having to make the pair, so it will be awhile. Thanks again.
