QED Reference High Resolution USB A-B Cable 1 m

REFERENCE High Resolution USB

New for 2020 comes an improved and updated QED Reference High Resolution USB cable with a slimmer, more flexible profile and enhanced performance.

In common with all QED cables, Reference High Resolution USB is informed by the results of exhaustive research into cable design which was begun in 1995 and recently detailed in the updated Genesis Report. This report sets out the design principles to which QED adheres and which resulted in the development of a range of cables which represent the ultimate expression of sound through science without compromise. Reference High Resolution USB is the state-of-the-art offering from QED and as such represents the pinnacle of QED's understanding of this complex cable application.

Key Features:
- Impedance Controlled Data Lane - 24 AWG, 99.999% oxygen-free copper twisted-pair with low-permittivity foamed-polyethylene dielectrics, uniformly bound by an aluminium/mylar wrap
- Clean Path Audio™ Technology - data lanes electrically isolated from USB power conductors using a double layer shield (aluminium/mylar wrap and shield braid connected to ground)
- Ferrite Insulation™ Technology - integral Zn/Mn floating ferrite jacket absorbs high frequency noise for a quieter electrical environment
- Ultra-low Jitter Geometry - exhibits 50% less jitter than a comparable cable without the ferrite jacket
- High Resolution Audio - impedance strictly controlled to 90 Ω +/-5% with a 100ps rise time for a 3m cable, exceeding the USB 2.0 standard by more than half
