I agree with Lak's recommeded trial order.
FWIW, I have bought many $2K+ cables/cords sound unheard. That is what the Audiogon buy n' try method is all about. If it works, keep it, if it doesn't sell and move on. I still lose less money in the long run than buying from a dealer.
Besides, even if you are listening in a dealers showroom, there is no guarantee that it will sound the same in your room/system. Cables and cords are very system dependent. The ONLY way to audition is in your own system.
Also, as Mitch has referred to, as you change gear, many times this warrants changes in cables and cords too. I've tried DSA cords a few times, as I tend to have a love/hate relationship with them. I love the midrange, it's beautiful, but the bass always seems too overblown for me. It seems to detract attention from the midrange and call attention to itself.
