After all this snake oil talk I really want to know what you guys use in your $20,000 + systems. Do you use Home Depot, Radio Shack, let me know. You are starting to sound like the infamous Julian Hersch from the old Stereo Review, if it can't be measured it's not true and all components that measure the same sound the same.
I've had many cables in my system for testing, power, analog interconnect, digital interconnect etc. I have done exstensive A/B and long term evaulation with many people participating and the panels blind opinion came up with with couple favorites. They however did agree there was a difference from one cable to another. I do think for example there is a sound difference between silver and copper all things being equal.
I do understand if you don't have the money to spend on cables it is human nature to say, it makes no difference. But in this forum I'm very suprised to hear all the snake oil talk. It seems it is based on principal not on evaulation.
Please check my system in my profile and you should hopefully see I have a rig that can tell a difference in cables and I'm glad myself and my panel can hear the difference because it makes everything sound better. BTW I've heard the Synergistic Research test at three different CES shows and I don't think it's fixed and I do think they have very good product that does make a difference with the active shielding application.
Cables tested: Nordost,Audioquest,JPS,Siltech,Kharma,Kimber,Cardas,ESP,Supr a,Harmonic Technology, PS Audio , Hovland,Shunyata, FIM, Cable Research Labs,Synergistic Research,Aural Symphonics,Custom Power Cord Company. Not including what I have heard at shows.
Good listening and enjoy the music
