It's inevitable that everyone will post about their favorite cables. I'm no different. I'm partial to Nordost products. All power cords, interconnects and speaker cables in my system are Nordost.
I've been an audio hobbyist since the early '80s. I was also in audio retail for years. I've owned cables by many different manufacturers. I won't list them now because I don't wish to disparage anyone. What doesn't work for me might be just fine for someone else.
In My Experience, Nordost cables pass more information and editorialize less than other cables. I urge you to seek them out if possible. Also, I believe in using cables of the same manufacturer throughout the system.
Honorable mention to Analysis Plus and Shunyata cables.
Good luck!
