This is a follow-up to my earlier report in this thread on my Clou Red Jaspis cables. I believe they are now pretty much broken-in. I've always thought of my combination of Senn. 580s and Max as kinda dark and a little lean. Well, not anymore.
The sound has become much richer and full of life. It is much easier to hear cymbals nows. Still not what I would consider bright, but just right. Vocals sound more palpable, and thus somewhat closer. The increase in instrument separation and detail is really impressive! Much easier to differentiate and locate guitars, violins, etc...
Perhaps the most startling improvement I've found is the bass. Yes, I realize most people haven't found any improvements in this area, but I have, and I'll back up ai0tron on this. It's like the old cord was throttling the physical impact of the bass. Bass notes I was hearing and feeling a little before are much tighter and cause more of a physical impact. Actually, on a few songs there is almost too much bass now. Admittedly, I hear this more on some cds than others.
Now, as others have mentioned, there are a few drawbacks having to do w/ the cable itself. Personally, I don't mind the red color, others may. The first annoyance is the cable stiffness. Definitely less flexible than the original cable, but not so much that it really hampers placement. The second annoyance is a little bothersome for me. Not only is the cable stiffer, but it's also heavier. This means it pulls my 580s down on my head enough to be a little uncomfortable after awhile. Have to figure out something to do about that.
So the bottom line is this cable was worth every penny I paid for it. The improvements I hear are not subtle, much better than what I thought a cable could do. Part of that I'm sure is that my source and amp are very good as well. Highly recommended!
