Simply put, any cable in the Cross or Golden line are the older versions which have less transparency with more warmth and highs which are not very extended. The Clear line offers more realistic and organic sonics with more detail and extension. "Legacy" lists the Clear Light which is a lower cost version of the Clear. But it also offers Golden cables which have the earlier Cardas sonic signature.
A couple of Cardas speaker cables (not all of them) have high capacitance values.
This does not have any affect when used with tube amps
However, some High Current design solid state amps will self destruct due to oscilation - Ayre and Gryphon are two that a friend "fried" with his Cardas cables - he had no idea of this issue when he fried his Ayre - he then fried the Gryphon, which was on loan - even the tech that repaired the Gryphon was not aware of the issue
NAIM warns of this issue on their web site - not many brands do that
I only know about it because I have a NAIM amp - so I looked at their web site before choosing speaker cables.
So, do your homework first - or it can get expensive :-(
Very interesting @williewonka and surprising, considering Ayre has had major partnerships with Cardas, and even an Ayre branded Cardas made speaker cable series. In fact, Cardas is the brand that Ayre mentions when you talk to them directly.
I have ARC tube gear, a Ref 6 and Ref 150SE and Clear Beyond XLR is magical between the two and Clear Rev 2 is likewise the best of several speaker cables I auditioned to power my DeVore O/93's. It is without a doubt system dependent. It is one of those maddening things about finessing the very best out of your gear.
That’s some fine gear. I know Focals have good high end extension and clarity. The Neutral Reference are very neutral, a different signature than the Cardas house sound, and the Cross are very coloured and warm, lacking detail.
The question now is which line of Cardas will play well between an Ayre amp and Focal speakers. You can audition cables thru The Cable Company, but since you are buying used, hopefully you’ll get some recommendations now that you have listed your components. If you are looking for transparency and dynamics, the newer Cardas would be the way to go.
Since a double run of Clear for biwiring would be too expensive for me, I am considering to move from Golden Reference to Clear Reflection.
When I made the same upgrade of the Interconnects, I had better imaging, more refined and extended frequency extremes.
Later the Reflection have been replaced by Beyond Interconnects, but I can't afford a biwired pair of Beyond or a double run of Clear speaker cables (it's the same), so the double run of Reflection is the best "real world" option for me.
Waiting for your inpressions, I ask to all if anyone did compare Golden Reference and Clear Reflection speaker cables.
