Trio

admin — Wed, 08 Jun 2011 21:42:30 +0000

Our smallest model, which has won many listeners’ hearts. A cable that is easy to live with, flexible and thin, it can be adapted anywhere and stored discreetly out of the way if one wishes to. Trio signal cable consists of three finely rolled fine silver conductors; Trio speaker cable consists of 2×3 fine silver plated conductors per. channel.

TRIO unbalanced signal cables are terminated with WBT NextGen Silver, which is laser welded to the cable, or with OYAIDE SLSC silver plugs with laser welding.
TRIO balanced signal cable is terminated with OYAIDE FOCUS XLR connectors with laser welding.TRIO speaker cable terminated with WBT NextGen Silver spades / bananas, which are screwed onto the cable, or with laser welded OYAIDE spades.TRIO cables are available in +99.99% pure silver, or (on special order) +99.99% pure gold.

The name HEXIA relates to the fact that the cable is constructed of 6 conductors. HEXIA series is based on an entirely new principle invented by Soeren Bertram, which we call ‘Diffused Magnetic Field’. Each conductor is made of a finely rolled strip, which is shaped like a sine wave, and then twisted a little bit. Why? Because we thus diffuse each ribbon conductors’s ambient magnetic field. This means that the cable gets considerably smaller inductance because the magnetic fields between the cores is reduced. This implies again that the cable is ultra fast and has very low internal resistance and very low distortion. Moreover, the manager’s contact with the surrounding Teflon tube is reduced to a negligible size, which means even less staining of dielectric as the ribbon conductor is virtually ‘free floating’. The diffuse magnetic field works both ways – in and out of line. This means that conductors in the cable work much less like antennas – and therefore do not pick up all the noise that other cables do. All this make the HEXIA sound like a fantastic pure and holographic reproduction. The cable has a vanishingly low internal capacitans.

OCTO signal cables cables have 8 conductors

OCTO speaker cables have 8 conductors for plus and 8 conductors for minus.

OCTO’s conductors are each rolled 8 times – every time in the same direction – to achieve the very fine structure in the silver, which is the hallmark of a Bertram cable. The very high material quality rubs off on the sound signature from this cable: Extremely well dissolved, fast, and with great authority and dynamics. Soundstaging is excellent.

OCTO has (like all our cables) ultra low capacitance and fits all types of high-end systems.

Ultima

ULTIMA is our flagship cable. Here, nothing is spared to give full justice to even the world’s best Hi-Fi. Head material is in this case rolled no less than 14 times – in the same direction each time – to achieve the ultimate material quality that characterizes this cable. In the speaker cable we have 6 precisely twisted band to plus and minus 6 to. Each band has a cross section of 1mm2 of +99.99% pure silver or gold.

ULTIMA signal cable consists of two ultra-fine-plated signal conductors formed after ‘Diffused Magnetic Field’ principle and laser welded to the connectors. On the outside is a stout shield of pure silver, which effectively shields the delicate signal from external radiation.

ULTIMA cables are the result of our 20 years of know-how, and perfectly combines solid craftsmanship with sophisticated design philosophies and extremely high quality materials.

ULTIMA has (like all our cables) ultra low capacitance and fits all types of high-end systems.

Profile

admin — Sun, 07 Jun 2009 12:08:08 +0000

Soeren Bertram was born an raised on electronics. His father was an engineer and fiddled with electronics in his free time. Among other projects, he built his own amplifiers and loudspeakers, which Soeren and his friends were allowed to play with at times – and consequently took apart as little boys do. At the age of 8 years, there was a ‘Phillips Electronic Engineer’ set under the christmas tree – a collection of components that could be put together in various kind of electronic circuits. This gift was one, that gave much inspiration and a lot of funny hours playing with electronics.
Thus, Soeren inherited his father’s passion for electronics and started playing around with electronics too. Speakers and amplifiers at first – and later on cables as well. To this date HiFi is Soeren’s greatest passion and hobby, surpassed by nothing else.Soeren was educated as a classical dental technician in 1985 and currently makes high-end dental prosthetics from his own clinic. He has through this business access to the finest gold and silver alloys, which he expertly manages to use for his the Bertram cables. As a result all materials in the Bertram cables are made per Bertram’s exact requirements and specs.Bertram Audio was initially launched in 1990, at first with sales in the Scandinavian countries only, but has since spread out the distribution to most parts of the world.

Soeren Bertram is a perfectionist by nature and every single cable is hand-made through and through. Countless hours, weeks, years even have been spent fine-tuning the knowledge base that lies behind every cable.
To mention but a few examples, the silver thread in the cables are rolled very slowly and cautiously 18 times – each time in the same direction (!) until the structure of the metal is sufficiently good for the Bertram cables. Also, every part of the production takes place in Bertram’s own production facilities, so that every little detail is perfected and made to meet the high standards of the Bertram cables. Furthermore, every termination is laser welded whenever possible, to ensure unrestricted and pure signal-flow.

The Bertram audio cables have won several blind-test, e.g. the Norwegian ‘Fidelity’ #5, 2008, where the Bertram cables were up against some of the finest cables in the world.
See the test here.

The Bertram vision always has been and will remain: To create the purest audio cables in the world while at the same time making sure that the cables are magnificent to look at too.

Below we’ve featured a couple of glimpses of the making of the Bertram cables.
