Reference Optical Quartz is the first of its kind, consisting of 210 separate boro-silicate glass fibres.
The cable allows you to experience stunning sound when connecting DACs, TV’s, CD players and Blu-Ray players to amplifiers or receivers because it has a much higher bandwidth and only 1/10th of the attenuation of traditional acrylic fibres.
Reference Optical Quartz vastly exceeds the demands for high definition multi-channel digital audio with a bandwidth of over 150MHz which is totally unaffected by bending the cable.
FEATURES AND BENEFITS
QED's new Glasscore™ technology employs multiple fibre bundles of ultra-fine boro-silicate glass optical fibres (GOF) of no more than 50um each to make up the 1mm diameter necessary to conform to the Toslink standard connectors. Because the fibres are so small the different paths taken by the light rays are similar in length virtually eliminating the timing error and introducing less distortion and jitter. This has the effect of increasing bandwidth and the accuracy of the data transmission.
STEPPED REFRACTIVE INDEX
The quartz fibres are coated with a cladding of low Refractive Index to guide the light signal.
OVER 150MHZ BANDWIDTH
This vastly exceeds the demands for high definition multi-channel HD digital audio. In contrast to conventional acrylic glass optical cables quartz glass cables can deliver signals up to and including 24bit/192kHz with very low jitter .
Reference Optical Quartz can provide a much higher bandwidth than a single acrylic glass fibre with 1/10th of the attenuation.
ULTRA LOW JITTER / ULTRA LOW LOSS
QED have calculated that jitter (distortions caused by timing differences between the different light paths) in conventional optical cables could typically reach up to 145ps. In Reference Optical Quartz, timing errors are virtually eliminated, introducing less distortion, jitter and ultra low loss < 0.03 dB/m.

Purchasing an audio product on the internet is not the easiest of tasks when you can't experience the most important factor - how good does it sound?
We only sell quality products that we're happy to have in our own homes.
But we don't expect you to simply trust that the products on our site are good quality, so we've implemented a few things to help give you confidence.
Each of these individual guarantees and warranties have been wrapped up into the K&B Audio Happy Sound Guarantee!
THE HAPPY SOUND GUARANTEE
1. THE BEST Returns & Exchange Policy
Quite simply, if you are not happy with the quality of the speaker(s) that you buy from us then you can either;
1) return all or part of your order and exchange or upgrade for a different system/speaker* or...
2) return them for a full refund
The ONLY question we will ask is "Can we help you choose a different system/speaker?".
We would recommend that you keep all original packaging for the Happy Sound Guarantee period, returns without packaging will incur a 10% restocking fee.
2. Extended Returns Period
We know that our products are often project based, we know you might be buying it now for installation a few weeks down the line.
So we've extended our returns period from the industry standard 14 days to a 60 days!
You can return the system for any reason during this period.** Please keep the packaging :)
3. Extended Product Warranties
Electronics are usually only covered by a one year warranty.
But we don't think that's good enough considering you have to cut holes in your ceiling!
We've managed to negotiate extended warranties with our best-selling brands that you won't get anywhere else.
Lithe Audio - 2 Year Standard, 1 Year Extended = 3 YEARS TOTAL
Systemline - 2 YEARS TOTAL
KB Sound - 2 YEARS TOTAL
Monitor Audio Passive Speakers - LIFETIME
Q Install Speakers - 5 YEAR WARRANTY
Please check individual product pages for an accurate warranty length for that particular brand/product. If in doubt contact us on 02393 190955
4. FREE Tech Support
When you choose to buy from us at K&B Audio you'll also get access to free technical support before, during and after your project.
We can help you with project design, specification of projects, how to wire and install all of the systems we offer.
Once you have your system installed we can also help with how to use it, how to get the most out of it and anything else you need assistance with.
* upgrade costs must be paid in accordance with the prices shown on our website.
** unless the goods are damaged on delivery or faulty the return postage costs are to be covered by you.
Buying from us gets you a whole host of extra features and guarantees that can't be matched by most other retailers including big-name marketplaces.
