Well, this is unfortunate on the 1960 4W. I had it briefly, but now have the 2W and the 1950 instead. It is not a warm cable to my ears and if I did a blind test, I would probably call it a silver cable nine times out of 10. The 1950 is even leaner, but a little less sparkly to my ears. Treble on the 4W is quite prominent and it sounds like you might actually prefer the 2W. Sorry, I have been through this many times and like Proedros says, you win some and lose some. I have lots a TON on cables, but I think you know this. Didn't I sell you that Z1R?
As for the comparison to Horus, it's important to remember that gold-plated silver can sound wildly different from one manufacturer to another. The Horus is one of the brightest cables I have ever heard. I paired it with my Legend X and it was fantastic. Anything else, it made it sound thin and way too sparkly to my ears (and I love me some treble). It does not surprise me that the GPS from PlusSound provides a different sound.
Happy hunting - you'll find something you love
I'm sure. Perhaps one of the new Monile offerings? I think they are supposed to be quite smooth.
