If you have the option of balanced interconnects then Audioquest Wild Blue Yonder will give you a fabulous window on your music. The subtlety and dynamics are in the very top class, along with tonal truth and timbral accuracy. Effectively, they have no sound of their own and just let the music flow. Almost any other cable will sound muddy by comparison.  I bought these cables new for $7500 and the only reason I am selling them is that I have downsized both house and hifi and have bought KEF LS60 wireless speakers which, of course, do not need cables. As you can see I have the original box and the elaborate sleeves the cables came it. They can be shipped safely.  The cables are very stiff and secure and the terminations are of the highest quality.  https://www.audiodrom.net/en/special-edition-reviews/61-audioquest-wild-blue-yonder
