Hi dear fellows.After 120 hs of break in the FI 11- N1 gold furutech Ac connectors, I still notice improvements in sound qualities.It seems the sky is the limit for this connectors!!Respect to last week listening , they gained in more depth in soundstage,instruments are more separeted in the scene as in a stage in a living concert, voices are more upfronted so you have more 3d sensation and more real sound.I think this process will take 200 hs as Chris Venhaus of VH Audio suggested and Michelzay of Audiogon says.My suggestion is that if you want to upgrade AC connectors, these ones are an excellent option.I feel like if I upgraded my PAD musaeus for a higher cable in the line.I`m very happy!I will write later when I notice any other improvenments.Cheers!Raf
