Scott, here's a little more that I wrote up for a couple customers:
The best I can do to describe the difference between stock cable and Jena is you get a more solid, substantial, and full sound, that seems larger or on a bigger scale. The dynamics get bigger (i.e. difference between tiniest sounds and loudest sounds seems to increase). The background gets darker and sounds are thrown into sharper relief/focus. If you close your eyes like I do and try to picture the performance in your mind, this process becomes easier; you have to work less hard to reconstruct the image, if that makes sense.
Because it is a fast and dynamic cable, the Jena is going add solidity and impact to the bass and drum hits, but you also get improved bass tone with more mid and upper bass info. As I say in the ad, the Jena cable is a lot like getting more water through a bigger pipe; there's just more of everything, but it's all in proportion to one another, so it doesn't sound "colored".
So that means an increase in top-end extension as well with a much more articulate treble than the stock cable. The Jena is much more like an open window on the signal coming into it; if the recording is bright, or if the components ahead of it are overly bright, it will show you that. If something has dead neutral/natural treble or is even rolled off, that is what you will hear. It does not "add" more treble to what is already there. But the treble has much better quality than the stock cable, it's cleaner and less sibilant.
In short, the Jena is going to give you exactly what you put into it, and show it to you with great clarity and rich tonality.
Hope this helps, cheers.
