Optical Digital
Whereas there are a number of ways in which a coaxial cable can be designed and built – hence the numerous models in the digital coaxial range – an optical cable is somewhat more straightforward.
The medical-grade light-conducting fibre used in Kimber’s OPT-1 is, arguably, as good as it gets. The extensive R & D invested into producing the highest quality fibre for medical use has a direct relevance to the needs of audio applications: they both require a cable which will transfer light as accurately, cleanly and efficiently as possible.
The cable is then encapsulated in a thermal barrier that inhibits any potential heat degradation of the fibre optic. A mechanical damping outer barrier is also applied to further protect the cable from damage and, finally, the ends are cold-polished to further reduce the incidence of light reflection.

"Quality Always Shines Through"
I bought this cable over 12months ago n I've enjoyed every moment listening to the music come out of my speakers has it should do..I've added a few more items to my system with mains fliters n conditioners.The Toslink cable is the best you can buy n for the price you can't go wrong for my Dac streamer unit sounds amazing.

"Appearances Can Be Deceptive"
At first sight – out of the packaging – this optical cable appears to be terrible value for money; half a metre of thin black cable – very ordinary – with a small plastic Kimber connector at each end; the difference against optical cables where the connectors are made to look like shiny phono plugs (and the cable is a lot more robust) is very noticeable. Then one notices that the ‘nozzle’ which projects from the connector is a full millimetre smaller in diameter than is found on other cables and one begins to wonder whether this manufacturing precision might have a beneficial result in the transmission of the light pulses.Finally, one listens – and suddenly details from my CDs (almost all of ‘classical’ music), which previously were smudged and lost in the background reveal themselves clearly and explicitly (and the recorded environment has suddenly become a lot more transparent and quieter). Instrumental timbres are now distinctive, dynamics are dynamic(!), and voices, in particular, ring out clearly and humanly.
Light pulses are light pulses – surely – and I must be delusional if I think that different optical cables can produce different aural results, but my experience, at least, is that not all optical cables are created equal. The cable may look inconsequential but the improvement in fidelity is anything but.

"A Quality Product That Highlights The Detail Within Recordings."
I have used this to connect the DAC to my cd transport and I'm more than pleased with it. The quality of this cable is evident as soon as it's removed from the packaging. The cable is alot thicker than the one I was using ( which was from a well known audio cables manufacturer ). The ends make a good, solid connection that help to reveal the details within my cds. Well worth the money. The service from RA was first class. I purchased this at the NWAS a few weeks ago and would like to express my gratitude to Peter for the time given to me, and for the realistic and practical advice given to me regarding future upgrades for which RA will be my company of choice.

"Fantastic Cable"
May be a little bit thin, connecting it to a DAC the sound has greatly improved. Previous cable was not "cheap", around £30 / meter.

"Shining A New Light On My Av Experience"
Following a move and the loss of my dedicated listening room I decided to connect the Sony TV to my main system.I already had a branded optical cable so it was simple enough to connect my TV to my DAC.
The sound was ok, but a bit thin and uninspiring and I just assumed it was the nature of the TV and/or an optical connection.
The rest of my hi-fi cable loom is from the middle of the Russ Andrews range so I got to thinking...
Anyway, I needed a two metre run and for this there was a longish wait (about five weeks), but to be fair this was made clear right from the day of the order.
So it arrived and was quickly installed. What a difference. Seriously, this wasn't a "bit of an improvement". I had bass (where had that been hiding), voices were very natural and the treble just shimmered.
Build quality and finish are first rate so I am expecting many years of improved sound. Highly recommended.
