Synergistic Research Element Tungsten 5' AC Cable15 Amp [Template]

This 5 foot, 15 amp SR Element Tungsten AC cord come with the original 3 tuning "bullets" (black, gray, and silver) - and 1 of the newer silver "UEF Tuning Circuits" which is an updated bullet; it's the grooved one in the pic. There are articles about the UEF TCs online for further research and they sold for $150/pair when purchased separately. The black bullet imparts a darker sound to the music, gray allows more high frequencies to the music and the silver bullet has the most detail & brightness. I always used either the silver bullet or the silver UEF TC, the latter adding a bit more detail to the sound. (My new amp won't fit in equipment rack and so it needs a longer power cord for its new location off to side on amp stand.)
