We offer our current 'Reference' YFS USB 2.0 interconnects in a 'Data-Only' option, a 'Standard' option as well as a 'Dual-Headed' or 'Split' option. The 'Data-Only' USB cable is just like the name sounds. This is your typical USB cable design with the +5V power lead removed. The ground lead is intact. The 'Standard' option is the conventional USB design with all 4 conductors intact. The YFS 'Dual-Headed' or YFS 'Split' Ref USB cable along with our YFS PS-5 power supply are specifically designed for DAC's using the XMOS, Tenor, and C-Media USB input chips. This design isolates the data leads from the power leads until the two meet at the DAC's input. It doesn't seem at first glance that this split cable design should elevate performance. We didn't believe it either so we tried it and sure enough there was an audible difference between the conventional USB design and the 'Split' design. Isolating the data and power leads appears to limit interference between the two which results in deeper, wider, more accurate soundstage and more separation between instruments and overall better presentation of the music.
