I don't have a useful comparisons to other wires for you. But I do own Styx because I bought into the whole Decware sound.  Avoiding the audio component merri go round, I voted with my $$$ to trust Steve's choices from speaker to cd and dac.  Love every Decware thing I have.

About the speaker wires...  I do have some old monster cable wire that doesn't sound as good as the Styx.

I think I read it here somewhere and I believe that wires, being passive devices, can do only two things: get out of the way, or block something.

In the worst case, they can block the signal entirely (broken wire), or they can have inductive and capacitive effects that roll/tip frequencies or even smear signals.  

In the best case, they can do absolutely nothing to the signal, as if the speaker terminals of your speakers and amp are connected directly to each other (zero wire, no loss, pure fidelity).  (of course we would lose sound stage if we parked our speakers and amps that close together).

So, I want in my system, the fattest economical electrical pipe, least likely to impede and resist the signal.  That's what Styx are to me:
Fat (largest we can fit into the terminal hole. least resistance).
Silver (least resistance).
SilverPlated (economical).
Individual separated wires (lower capacitive, inductive issues which alter tone).
Teflon dialectric, blah blah. etc.

While I have not compared them to expensive cables, they sound great to me, better than anything else I've heard, and they best match my criteria for what an ideal wire should do: get out of the way. (if that reveals that an upstream Active component is too bright, then I have to deal with that component.)

I don't have the experience to describe them as fast, bright, analytical, transparent.   I'll say, for your Amp and Speakers, Styx know best how to show them the Love.  (bring them closer together, electrically).  :D

Um, no, there is no end.

That's why I settled on Styx. Sounded as good as, or better than, all others I had heard. Their transparency, speed, and detail mate well with Decware electronics and speakers.

I am still burning in my Zen Styx (with Silver Banana plugs), in my Bedroom System. I did not want to introduce two changes to my system at once when I got the Super Zen CKC & the Zen Styx.

The Super Zen continues to burn in and bloom.....I can't say enough about it.....open and Organic. As for the Zen Styx, they are fast and articulate (I like um') and with more time on them I will bring them in to the Listening Room System and see how they fare.   -Stone

PS-I am finally joining the efficiency camp. My Zu Union's ship out to me today! They have 600+ hours on them from the factory and after I have a handle on them and placement.....the Zen Styx come in.
