Easy Returns

If for any reason you are not happy with your order and wish to return it under current Consumer Protection Law within 14 days, OR within our 30 day No Quibble Return Policy, subject to the following conditions:-

Please call us first to discuss why you may wish to return an item. We will take all steps possible to solve your problem / offer you a replacement or exchange product, or a refund. If the goods are to be returned, in all circumstances you must obtain an RMA Number (Return Material Authorization) from us before returning. 

A) If you notify us of your wish to return an item within 14 days of the date of delivery.

It is the responsibility of the customer to return the item and ensure the package has been reasonably protected in return transit. You must include a copy of your invoice with the return. Provided the item is in a re-saleable condition, (i.e. unused, unmarked, un-assembled and in original unmarked packaging) we will refund you the full price that you paid for the product including any standard delivery cost. There are numerous delivery companies that offer online or phone bookings for insured collections and delivery back to us of unwanted orders at very competitive costs. We can assist with advise on this if you call us to request such. 

For non-furniture packages up to 30Kgs, if you wish, we can arrange collection during normal working hours - week-days only, by our delivery company, but you should understand that this service bears the cost of collecting the goods from you AND delivery back to us. If you chose to use this service, then the goods are then covered by our delivery company whilst in transit - provided you have correctly and fully repacked the goods in the original packaging. The cost of this service can vary between typically £20 - £30. If you are not available for a pre-arranged collection, then you must bear the cost of any re-arranged one also.

For Furniture, any item including glass and larger items over 30Kgs, you will need to make your own arrangements to ship the items back to us. You may find that the cost of such may be high, perhaps between £20 - £50. For larger items that have been delivered by one of our one or two man services the return cost may exceed £100. In these instances once you have an RMA Number, bringing the item back to our showroom at NG19 9BG may be a good option.

PLEASE NOTE With many of our special delivery services for larger furniture items, you will have the opportunity to inspect the item when it arrives, and if for any reason you decide it is not really what you expected, then you can ask the delivery company to repack and take the item away immediately. You will be liable for the return costs, but these will be less and more convenient than returning the item later. 

B) If you notify us of your wish to return an item within 15 to 30 days after delivery

Our no quibble returns policy extends your statutory rights for up to 30 days after delivery.

It is the responsibility of the customer to return the item and ensure the package has been reasonably protected in return transit. You must include a copy of your invoice with the return. Provided the item is in a re-saleable condition, (i.e. unused, unmarked, un-assembled and in original unmarked packaging) we will refund you the cost of the product minus the cost of shipping to you. There are numerous delivery companies that offer online or phone bookings for insured collections and delivery back to us of unwanted orders at very competitive costs.

Conditions and Important Notes

ALL PRODUCT PRINTED PACKAGING MUST BE PROTECTED BY WRAPPING / PLACING IN ANOTHER BOX SO THAT NO SHIPPING OR RETURN LABELS ARE ACTUALLY PLACED DIRECTLY ON THIS PRINTED PACKAGING. Where a customer returns their order because it is no longer required, AV4home.co.uk reserves the right to recover the true original delivery costs. This is applicable to orders sent using our free delivery service. Where the customer returns an item that is part of a reduced price/free promotion, the customer will be expected to return all items received as part of the promotion in as new, unused, unopened perfect re-saleable condition or pay the current value for any items not returned. 

Cancellation of Order / Return of pre-assembled furniture and B2B (Business to Business) purchases may be subject to a restocking charge. 

Cancellation of Special Order Items, such as furniture made to order, bespoke colour and selected features – as usually depicted on the website and identifiable by their longer delivery times, will not be accepted or at least will incur whatever cancellation costs that may be imposed by the manufacturers of the item due to work completed at date of cancellation up to the full cost if the item is complete and enroute / delivered to the customer. 

This policy only applies to Consumer Customers, not to business.

Description

QED's Reference Silver Anniversary XT Bi-Wire speaker cable is the "big brother" of the multi-award winning cable that continues to demonstrate QED's commitment to superior, high quality sound within an affordable loudspeaker cable. What Hi-Fi magazines "Product of the Year" for 3 years running, Silver Anniversary XT has been specifically designed as the natural replacement for the multi-award winning Silver Anniversary speaker cable. Combining the features of Silver Anniversary with the added enhancement of X-Tube™ technology to combat the skin effect and deliver stunning detail.

The Silver Anniversary XT Bi-Wire is still a What Hi-Fi top 3 cable for "star rating" (This rating has been valid since February 2011, last checked June 2014). This loudspeaker cable features Aircore technology to offer superb transmission of your audio signal from source to speaker, while maintaining a smaller-than-normal cable thickness to provide excellent use within a typical home AV and Hi-fi system.

QED Silver Anniversary XT Bi-Wire provides excellent tonal quality in all frequencies due to the research and development invested into the QED Aircore technology and in this bi-wire cable specifically. The Silver Plated, Oxygen Free Copper stranded conductor is braided around the colour-coded, hollow Polyethylene core so whether you decide to have this cable professionally terminated or simply want to fit your own connectors, this cable will provide excellent surface contact from conductor to the audio connector to offer superb sound quality.


X-TUBE™ WITH AIRCORE TECHNOLOGY HOW IT WORKS


One of the biggest problems facing speaker cables is keeping the inductance low as cable conductor size increases. This is vital to reduce cable losses and prevent inaccuracies in the signal transfer process, i.e. distortion. The normal way to do this is to use a number of individually insulated conductors within the cable construction. This method is utilised to great effect in the design of the QED Genesis Silver Spiral loudspeaker cable, however this results in a product that has a very high quality sound performance, but is expensive to manufacture and can be difficult to terminate.

To take advantage of this design ethos, but in a more conventional format, X-Tube™ forms the conductor in the shape of a tube with an inner Aircore. This has the same effect as using multiple insulated conductors and ensures that high frequencies are transmitted cleanly, with the added benefit of ease of termination. This unique tubular conductor geometry also provides lower flux density within the conductors, which gives improved transparency to the sound.



THE SIGNAL

1.) At low frequencies both X-Tube™ and conventional stranded/solid core speaker cable convey signals in a linear way. This is represented by the uniform green colour of the strands shown in the two diagrams above.

2.) At higher frequencies X-Tube™ retains a near-linear signal transfer, whereas the conventional stranded/solid core cable fails to efficiently conduct higher frequencies uniformly across the entire conductor area. The diagram shows excess current density at the periphery (designated in red) and rapidly deteriorating current density (green through to white) towards the centre of the conductor.

The effect of this is to reduce the actual cross-sectional area of the cable at 15kHz to less than 75% of that at low frequencies. The result is induced distortion and a compromise in the performance of the cable.

X-Tube™ with Aircore technology exhibits much lower self-inductance and is therefore less affected by this problem. The use of an innovative Polyethylene Aircore enables a reduction in loop inductance to levels only usually achievable by using more costly and difficult to terminate cables.


This cable offers 4 x cores suitable for advanced bi-wire speakers and hifi requirements, and the inner cores are Red / Black / Yellow / Blue for easy identification of the different poles.
