The Muon Pro was clearest, Cm audio a close second in clarity but maybe more body to the music. The Fiber Box a little thin overall. Of course this is through computer speakers but I can hear the difference.
Think it’s definitely personal choice. After listening to actual Crystal cable, all my live test tracks like MusicaNuda’s I Will Survive and the live audiophile recordings even late Jeff Beck’s classic guitar track Crystal cable is so much Preferred surely.
Having said that the differences are quite minimal except in the track "Dance in the Knights" where the violins are perceived much more extended , in "ito" the voice is a bit more natural , but the performance "William Tells" the performance is superior without the Puritan. I would say that it would be neither a big sonic change, nor a big investment, just put a Furutech wall-mounted NCF type and a dedicated line, to have huge advantages and a tenth of the expense .........................
