This is where auditions become a necessity. For all the rich guys here, they may not blink an eye at plopping down $5-$10k for speaker cables, but not for me. Tellurium Q is also an interesting brand, but one that's not easily accessible in the states - the Black IIs have impressed me for the price, they're also ribbons, although they don't do what Fideliums can. Then again, I don't want to drop $3-6k further up the range to find out. I've got a whole list of cables to try - Silnote Poseidon, Shunyata v2s, Kirmuss, ZenWave, Grover Huffman, it's a crowded market.
The reviews though in The Sound Advocate and Enjoy the Music were so out there with praise that it was really a no brainer to give these a try.
