What do audiophiles want from a cable?

@maplegrovemusic , thanks for the new information!
That breaking news changes everything!

You do know that brainwashing works both ways, don't you?
If you don't want to hear a difference, you won't.

I got a pair of speaker cables to sell..
 
They're made of military and aerospace grade beryllium copper, harvested from fragments of a comet that only passes near earth's orbit every 100,000 years. 

These cables are then coated with platinum, because everyone knows platinum is better than gold. 

The cable is cryogenically treated, then annealed, then treated again. This makes the cable resistant to electromagnetic interference due to its superior flux blocking grain structure. 

After about 100 hours of break-in, you'll hear immediate improvements in clarity, transparency, openness, resolution, and a lack of opaque..ness.  

You'll experience a telepathic connection with the musicians and hear all the subtle detail they intended you to hear, realizing that the cables in their recoding studios was comprised of this same magic formula.

Thanks maplegrove, I had lost that reference. 

@helomech  What length and how much?  Are they terminated in spades or bananas???

Inna, yes I have used Proteus Provectus which are fluid filled and solid core using some combination of the metals you listed in your previous post.  I experienced good results and I agree with your assessment of the qualities these different cables impart on the sound. This fluid filled cable worked very well from the Lampizator DAC to the McIntosh, and did mate up very well with the Venustas and other ferox cables that come later in the signal chain.  The ferox insulated cables seem to provide the SOLID, WELL BALANCED foundation for the music with the dead quiet backdrop you mentioned, while the Proteus Provectus(fluid filled) cables offer the mid range "magic" (similar to a good tube amp or tube preamp)that will inject a very lifelike, multidimensional quality to the sound system.  The Proteus Provectus interconnect, as good as it is, seemed slightly unbalanced in this system.  I heard it tilting the presentation a little too far forward in the mid range and upper frequencies for my liking.   Enter the Jade Vermeil Gold with Bybee purifiers to provided a truly special, spacious, palpable and utterly lifelike presentation of the music that works perfectly here with the ferox insulated PAD cables coming after.  This gave me a real sense of LIVE INSTRUMENTS AND VOICES which is my BASE REFERENCE for what this sound system should be able to reproduce bjg.  In my experience, this is what happens when cable synergy is there, and working its "magic" in the listening space with good equipment.  One should have a "you are there"or "they are here" type of experience when things are setup correctly and this so called "cable synergy" is in full effect and playing music.
