Shipping & Returns
Thank you for considering Yorkshire AV for your next investment in your AV or HiFi 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.
Who do you use for delivery?
Our primary delivery agent is DPD. Where orders are shipped directly from Yorkshire AV, we always use DPD 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.
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.
Certain product(s) are delayed in manufacturing due to semi-conductor shortages across the Globe. We'll keep you informed as to your order progress and a likely ETA once we get updates from the manufacturers.

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).

If an item states 'Available to Order' - 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.

Product details
Ordinary Headphones vs Mitchell & Johnson Electrostatic Headphones (ESL)
Ordinary headphones have a cone shape diaphragm typically made out of paper, plastic or metal. The techies know these as electro-dynamic transducers, and they work on electromagnetic principals and basically move air which arrives at your ears as a soundwave. Also, electro-dynamic speakers are a point source, meaning sound disperses radially from the speaker’s centre. ESL’s use electrostatic principals to reproduce which are very different from the principals above.
Instead of a magnet and cone diaphragm structure, ESL’s use a large, heavily biased (high voltage) ultra-thin plastic membrane ‘hat’ is sandwiched between two conductive stator plates to reproduce the sound.
The ESL is a linear source and the music disperses evenly over the whole surface of the diaphragm. They are also dipole, meaning sound waves radiate from the front and rear, and the membrane is not usually enclosed in a cabinet, thus the thin speaker profiles and unique acoustic qualities.
How Does this Technology Work?
The ultra-thin, almost weightless diaphragm, only microns thick, is sandwiched between two metal stators which carry the music signal and push/pull between the electric fields of the two.
This technology extends its frequency range and response beyond human hearing, vital for the harmonics in all music, encapsulating true sound reproduction which is natural, vibrant and real.
The response is amazing, as the entire membrane moves briskly and uniformly, with no cone breakup or resonance to colour the sound and generate distortion you can find with ordinary electrostatic headphones. The Electrostatz film holds a constant electrical charge, instead of constant voltage (ESL) and is non-conductive, so the issues of distortion are absent, unlike its ESL predecessor.
The real magic happens when you create a Mitchell & Johnson hybrid electrostatic stereo headphone combined with a traditional 40mm paper based dynamic driver, so you get 2 in 1 ,crystal clear precise details and punchy bass as well.
