Cardas Sennheiser Replacement Cable For HD580, HD600 & HD650

Cardas cables have a good value for the price.
I can't remember really how they sound anymore since I sold them a couple of years ago.

I'm not big into cables making a huge difference. I feel like, more than any element of audiophilia, the differences can easily be mental and not really there. However, I feel like this cable really brought out the best in my 650s. The thickness and durability is great and I love that I bought a lengthy cable. 
 
It might not be worth it to everyone, but it was for me. No regrets.

This cable improves the extension in both the treble and the bass and gives the whole spectrum a balance reminiscent of Beyerdynamic T1s. The Midrange becomes sweet and tones seem to take on a hue that serves to almost always improve the music. Grain seems to disappear, though transparency is only a little improved. The bass seemed to get deeper and also improved in tone.
 
Overall a big improvement in audiophile qualities in the music.
