Glasscore™ Technology - Straighter Paths, Less Jitter

Glasscore™ Technology - Straighter Paths, Less Jitter

Conventional optical fibres are usually made from an acrylic glass material known as PMMA. The acrylic core allows the light to take many different length paths through the cable which is fine for most regular digital audio signals but does increase timing differences and jitter which high quality equipment will pick up on. Glasscore™ uses 210 tiny fibres smaller than a human hair which direct the signal down a straighter path through the cable keeping jitter to a minimum and delivering perfectly timed audio.

QED yet again continue to bring their excellent research results into the development of a new cable. The QED Reference Quartz Optical boasts a first of its kind Glasscore™ technology - a conductor packed with 210 boro-silicate glass fibres. This cable massively exceeds the bandwidth required for high definition surround sound broadcasts meaning stunning sound if you're using it to connect sources to AV amplifiers. 

QED have proven with undoubted success their ability to nurture and develop award-winning technologies. This time, Glasscore™ technology employs multiple bundles of ultra-fine boro-silicate glass optical fibres to send the differing light rays on a similar path which virtually eliminates timing error and results in less distortion and jitter.

The QED Reference Quartz Optical also supports 12MHz bandwidth, over double the capacity of conventional digital optical cables using single acrylic glass fibres. Multi-channel HD audio will sound as good as it possibly can do.

  • Tick Glasscore™ technology - 210 boro-silicate glass fibres at the core
  • Tick Each fibre is clad in low Refractive Index to guide the signal
  • Tick 12MHz Bandwidth
  • Tick Ultra low jitter and virtually no timing differences
  • Tick Protective PVC outer jacket

It has given an improvement over my existing cable. The improvement is not huge, say 2% or so but I thought my system was fairly good already.

I compared this directly with the Chord Epic digital coaxial cable, both fed from a Cyrus CDXt Signature, and this remarkable cable gave, to my ears, 95% of the Chord's performance - not bad, given the price difference!

Bought this to accompany my newly built Raspberry Pi/Hifiberry Roon Bridge > Marantz PM7005 amp. Delighted with the clean & transparent audio I'm getting with this cable, compared to my previous setup which was Mac mini USB output direct to amp ,using an Audioquest Carbon USB cable. The AQ Carbon is a fine cable which I'd highly recommend if USB is your preferred setup, however I found that separating the audio away from the Mac and using this superb cable from QED wth RoonBridgr is superb!
