The Jorma Phono cable is a distinctive design for your refined turntable system at reference level.It comes with optional XLR or RCA, DIN connector straight or 90°CopperOur loudspeaker cables and interconnects are composed of copper of the best possible quality.We decided to use this material after experimentation with many other materials, as well as with other copper configurations.Copper delivers the most neutral, transparent, and natural musical signal. All cables employ the purest possible copper. This purity does not only refer to oxygen, but to all polluting materials and metals.All conductors are subjected to a spark test using 6000 V impulse tension before we use them to produce our cables.TeflonThe dielectric of all Jorma Design cables is made of the purest, non-coloured Teflon.ConnectorsThe connectors we use are very carefully selected for the best sound quality. Where solder is used, it is also carefully selected for the same reason.The connectors for all cables are assembled with gold-plated copper crimps, with no solder employed.ConductorsThe filling in the conductors is a special ceramic glass fibre, with threads that is ultra thin. Inside the conductors are hundreds of these fibres, and around the fibres are thin copper threads wound exactly in parallel. The conductor therefore forms a very thin tube that varies in thickness depending on which series of our cables it is. We found that the thinner the tube is, the better-sounding results it gives. However, by itself, such a thin copper tube is not sufficiently stable for normal use. The solution is to twine the fine copper around a pure ceramic fibre filler centre to get as close as possible to tube form. While it is very difficult to produce conductors in this way, the finished product is very hard to damage.ShieldingJorma Design cables employ sophisticated shielding to reject radio frequency interference (RFI) and electromagnetic interference (EMI) and to stabilise the cables against vibration and microphonics. All Jorma Design cables (except power chords that has a different type of steel shielding) are heavily shielded, with a tin-plated copper that works very effectively in combination with the special geometry of the conductors to ensure that all of the incoming and outgoing RFI and EMI are removed without any compromise to the audio signal.StructureIn addition to the use of the finest materials in all aspects of their design, the unique structure of Jorma Design cables contributes to their natural sound.SizeOne question that is frequently asked about Jorma Design cables is: Why are they so thin? For that price, shouldn’t they be thick and heavy? The problem with taking diameter as an indicator of quality is that making Jorma Design cables thicker would adversely affect the sound. We have found that using the least amount of the insulation that surrounds the conductors results in the best sound. If we were to use more than is absolutely necessary to make the finished product strong, safe, and long lasting, it would degrade the sound. That is why our cables look as they do.Quality controlThe “secret” of Jorma Design products is that every cable is a carefully chosen combination of design and structure and that it uses the best materials in the world. Every Jorma Design cable has to satisfy strict criteria before leaving our factory, and every cable is individually tested to ensure that it meets those standards.The SoundEvery Jorma Design cable has to sound musical. Simple as that may seem, it is one of the hardest things to achieve in cable design. “Musical” means that the owner of our cables is able to listen and enjoy hour after hour of music in total enjoyment. With Jorma Design cables in your system, your concentration is only on the music. You do not need to worry about the pros and cons of the cables because they sound completely natural. They make it possible for your audio system to immerse you in a sound field that you have never experienced before.
