I am the original owner for this Audioquest Coffee USB A to B Plug .75M cable. This cable was purchased new and includes the original box. I moved some gear around in my house and am no longer in need of this USB Cable.
SOLID 10% SILVER
eliminate strand-interaction distortion and reduce jitter. Solid silver-plated
conductors are excellent for very high-frequency applications, like HDMI audio
and video. These signals, being such a high frequency, travel almost exclusively
on the surface of the conductor. As the surface is made of high-purity silver,
the performance is very close to that of a solid silver cable, but priced much
closer to solid copper cable. This is an incredibly cost effective way of
manufacturing very high-quality HDMI cables.
SYSTEM WITH RADIO FREQUENCY TRAP
between two or more conductors is also a dielectric whose properties will
affect the integrity of the signal. When the dielectric is unbiased,
dielectric-involvement (absorption and non-linear release of energy) causes
different amounts of time delay (phase shift) for different frequencies and
energy levels, which is a real problem for very time-sensitive multi-octave
audio. The inclusion of an RF Trap (developed for AudioQuest’s Niagara Series
of power products), ensures that radio frequency noise will not be induced into
the signal conductors from the DBS field elements.

Hard-Cell Foam (HCF)
Insulation ensures critical signal-pair geometry.
Any solid material adjacent to a conductor is
actually part of an imperfect circuit. Wire insulation and circuit board
materials all absorb energy. Some of this energy is stored and then released as
distortion. Hard-Cell Foam Insulation is similar to the Foamed-PE used in our
more affordable Bridges & Falls cables, and is nitrogen-injected to create
air pockets. Because nitrogen (like air) does not absorb energy and therefore
does not release any energy from or into the conductor, distortion is reduced.
In addition, the stiffness of the material allows the cable's conductors to
maintain a stable relationship along the cable's full length, producing a
stable impedance character and further minimizing distortion.
NOISE-DISSIPATION SYSTEM (NDS)
It's easy to
accomplish 100% shield coverage. Preventing captured Radio Frequency
Interference (RFI) from modulating the equipment's ground reference requires
AQ's Noise-Dissipation System (NDS). Traditional shield systems typically
absorb and then drain noise/RF energy to component ground, modulating and
distorting the critical "reference" ground plane, which in turn
causes a distortion of the signal. NDS's alternating layers of metal and
carbon-loaded synthetics "shield the shield," absorbing and
reflecting most of this noise/RF energy before it reaches the layer attached to
