DNM-reson
Original Mono Solid Core Cable
Since the early 1980's, there has been an increasing demand for high-quality interconnect and speaker cables. What began as a quest by music lovers to get that little bit more out of their hi-fi systems has grown into a multi-million pound business, full of marketing hyperbole, exotic packaging and enough expensive metal to build a ship!

 

 

 


Unfortunately, many of these over-engineered cables owe more to increasing the perceived value of the product than to improving sound quality. Ribbon-type solid core cable was originally developed by DNM back in 1984 and now has many converts. It represents the opposite approach to most of the audiophile cable market, but it is designed for domestic audio - and for that application we believe it is the best at any price.

The majority of cables used in audio have been selected for their low inductance, low resistance and high capacitance characteristics as measured on the test bench. These parameters define what are believed to be the electrical properties most ideal in an audio cable.

Applications, however, vary widely, from recording studios through public address systems and live concert amplification to the domestic, with each having its own particular demands. No multi-purpose cable can suit the precise requirements of the domestic music lover as well as one designed specifically for that purpose - as home listening tests prove!

There are good technical reasons for this. 
 

 

 

Eddy Currents
Once the cross-sectional area of a cable exceeds a certain size, things begin to go badly wrong with the sound. Complex interactions between the cable and the magnetic fields generated by transmission of an electrical signal cause circulating eddy currents, which also generate significant magnetic fields.These induced magnetic fields oppose the original signal - the result is distortion. In short - smaller cross-sectional area gives greater clarity.

When auditioning speaker cable, most of the differences heard are caused not by the cable itself but by the amplifier reacting to the revised loading of the cable. Large, multi-strand cables are recommended by some manufacturers because their low resistance is thought to maintain the amplifier's low output impedance. Whilst this is true, it has no sonic benefit at all because amplifiers sound better when driving through a resistive or inductive load.

A cross-section of the spaced pair DNM reson cable shows its simple, clean and uniform magnetic field frozen at an instant in time. It is easy to forget that music signals produce a complex, dynamic version of this picture-and the field interacts strongly with the conductors. Bearing this in mind, it would be amazing if different cable designs sounded the same - not amazing that they sound different!.
 

Large diameter high-capacitance cables connect the amplifier's sensitive feedback control system to a short circuit, a type of load that invariably worsens the amplifiers sound quality. !!!

Smaller diameter cables with higher resistance and inductance help to isolate the amplifier's feedback control system, improving clarity throughout the frequency range.

This argument for the speaker cables applies equally well for each element in the audio chain, other cables and even electronics. So the interconnect cable is equally important and amplifier design is influenced by these considerations as well.

The final proof is in the auditioning. Although our cables are inexpensive by high-end audio standards, we believe that they prove their worth, no matter how complex and expensive the competition! 
 


Connectors
A question often raised by customers concerns the use of plastic bodied RCA plugs on our interconnect cables. Compared with competitors, these plugs look rather inexpensive but they assist the performance of DNM reson interconnect cables. Using a cable so carefully designed to minimise magnetic effects with a large chunk of metal soldered on the end would be self-defeating.

Consequently, all our connectors have minimal metal content because metal is needed only for the signal path and the contact area.

This DNM philosophy is consistent throughout the product range. Its formulation is a result of careful research into the effect of dynamic magnetic fields on audio signals. Understanding field effects should no longer be a quantum leap in audio thinking - especially for a technology led industry

  stereophile review  ....

In particular, when using the DNM 3D Six preamp to drive the many tube amplifiers at my disposal, it seemed that the characters of those amps were especially well presented, even brought to the fore. If anything, the wonderful Quad II monoblocks sounded even more rich and luxuriant than usual. The flea-powered Fi amp seemed more tuneful than ever, with almost startling presence—again, more than I'd expected. And the Shindo amps were amazingly colorful, dramatic, and alive, the different flavors of the two different models being clearly laid out.

Was all that down to the DNM's low output impedance? Its lack of coloration? Its tendency not to pollute its electrical surroundings with noise? Was it the DNM cable? Or the simple fact that my equipment shelf was resonating at a different frequency than usual, given the reduction of the mass on top of it?

Darned if I know. But even as my faith in the DNM's unique musicality, and the almost peerlessly high quality of the thing as a piece of electronic art, remains rooted in place, I'm even more curious than usual to see what John Atkinson's measurements uncover.

In engineering, the difference between being correct in one's convictions and being merely doctrinaire is the simple difference between making things that work or making things that don't. On the evidence of his latest preamplifier—as, I admit, with every other DNM product I've heard—Denis Morecroft is clearly on the better side of that fence. The 3D Six is simply amazing. Few amplification products are more beautiful, more effective, more fun to use, and, consequently, more recommendable.
