In 1982 Sony gave us "Perfect sound forever," along with the attitude that, "it's just digital, so all CD players sound the same." That was disproved and qualitative differences between players became accepted truth.

Next came separate transport and DAC combos, which brought with it the attitude that "all S/PDIF digital audio cables sound the same..." until that too became disproved. Now the frontier has moved once again. Is digital audio really just ones and zeros?

We don't believe so, and once you've had a chance to listen to Coffee USB, you won't think so either...

The Coffee cables feature the 72V DBS unit, designed to remove harmful RF from interrupting the digital signal between your devices.

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. Our favourite cables when used with DAC's are the Coffee USB.

Available Lengths: 0.75m-5m

The USB series of cables from AudioQuest are:

Forest
Cinnamon
Carbon
Coffee
Diamond
Wild
WEL Signature

Coffee digital cables feature 10% silver with solid copper conductors. A 0.41mm gauge is supported by a hard-cell foam dielectric, a carbon-based multi-layer noise-dissipation Cold-Welded, Hanging Silver Directly Over Pure Red Copper termination. As you move up through the range to WEL signature, the conductors, noise dissipation and shielding all improve to improve clarity through reduced distortion and cross-talk between other cables.

Features

DIELECTRIC-BIAS SYSTEM WITH RADIO FREQUENCY TRAP

All insulation 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.

ALL CONDUCTORS CONTROLLED FOR RF NOISE DIRECTIONALITY

CARBON-BASED 3-LAYER 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 ground.

HARD-CELL FOAM INSULATION

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.

SOLID 10% SILVER CONDUCTORS

Solid conductors minimize the harmful effects of both electrical and magnetic strand-to-strand interaction. For digital cables, whose signals are of such high frequency that they travel almost exclusively on the surface of the conductor, increasingly thick layers of silver plating are applied to AudioQuest’s Long-Grain Copper (LGC) conductors to further improve Noise-Dissipation. Placing the superior metal on the outside of the conductor produces the greatest benefit on overall performance—a superbly cost-effective way to maximize a digital cable.

Thank you for considering Yorkshire AV for your next investment in your AV setup.

We are an approved retailer for all brands sold on our website, which means full manufacturers warranty and support as well as detailed product knowledge within our small business.

We use an inventory tracking system which states if item(s) are in stock and if not, what are the likely lead times.

Selecting "Next Day" delivery does not mean you'll receive your item the next day in some cases. It's the next day from when the item(s) are in stock with us. If there is an urgent need then please contact a member of staff via the Live Chat or telephone (01757 826111) to check on live stock levels.

We do ask for some patience during lockdown - we're working remotely from home and travel to the warehouse each day to fulfil orders. If item's aren't in stock - we can usually get them within a couple of days.

We're a small business that's been impacted massively due to COVID-19 and have such had a significant reduction in orders. We're focussing on core products and services with less frequent products being ordered "on demand".

When will orders be dispatched?

Orders placed Monday - Thursday before 2pm and are in stock will be dispatched the same day for next day delivery. This relates to product that state 'In Stock for immediate dispatch' on the product page.
Orders placed on after 2pm on Thursday or on Friday will be dispatched for delivery on Monday unless Saturday delivery is selected.
Orders placed over a weekend and are in stock will be dispatched on Monday.

Orders for items not in stock

Given the vast amount of variations of each product (e.g. AudioQuest cables) or Pro-Ject Audio Turntables - we keep the most common options in stock (i.e. gloss black finish, or 1.5m RCA cables) whereas longer cables or cables with terminations that are less frequently ordered will be ordered as required.

Generally speaking - we receive orders within 2-3 days for UK suppliers and 3-4 days for European suppliers (i.e. AudioQuest, DALI).

We want you to be 100% satisfied which is why we'll give you an email/call if item(s) aren't in stock and give you the option of changing the order, cancelling or if you're happy to wait a few days, we'll get it out as soon as possible.

If an item states 'Available to order. Usually dispatched within 48 hours' - this means the item is not in stock but we are able to order in. Lead times average 2 days but in some circumstances, delivery times may be longer and is outside of our control. Please contact us to get an estimate on delivery times if orders are urgent.

Who do you use for delivery?

Our primary delivery agent is DHL. Where orders are shipped directly from Yorkshire AV, we always use DHL who offer a fabulous service at competitive rates.

If we drop ship (i.e. direct from the supplier) then the delivery agent is out of our control. It is generally DPD or UPS however - we rarely see other carriers used.

As always - we welcome a conversation about your requirements and will always explore all options to connect you with the right solution.
