I purchased Vampire C7X RCA connectors and Canare GS6 cable and made my own custom length cables yesterday. I must admit I was skeptical of all the hype, but I can now tell you the difference is absolutely amazing! I always felt there was a degree of white noise in the system and tried many things to clear it up, nothing has helped until the installation of these cables (source to preamp,and preamp to power amps). The clarity with depth to sound was noticeable immediately upon turning the system on.
