Product News & brief product details



NEW - DNM Stereo Solid Core Resolution 2 Speaker cable
DNM Stereo Solid Core Resolution 2 is a ribbon speaker cable with very advanced design.
Designed for use with normal-to-low sensitivity loudspeakers DNM Resolution 2 improves on the audio performance of DNM Precision 2 but it can be used with larger audio systems, longer cable runs, speaker sensitivity below 89dB/watt and more powerful amplifiers.
Full Resolution 2 announcement details here.

The ribbon dimensions are set to reduce the capacitance and slightly increase the inductance, to ensure amplifier stability with longer runs of cable. The result is a stereo ribbon 22.4mm wide and 2.4mm thick with the same facility for easy installation as the Precision cable but with a much higher performance when using medium to low sensitivity speaker systems.

The DNM Resolution 2 ribbon contains four 1.2mm diameter high purity copper conductors. A single length of DNM Resolution 2 connects two stereo speakers or one bi-wired speaker. Easy-separation lines in the ribbon make cable preparation very easy.

The unique design of the DNM ribbon places the conductors above the ribbon's centre-line to project the magnetic field through air rather than insulation material. The cable's structural Q is low because the easy-separation lines also reduce the ribbon's stiffness.

Visually DNM Resolution is equally advanced, with a semi-transparent outer ribbon and coloured insulation on the conductors but a third layer of brown insulation makes the ribbon appear light brown and it blends into the background in the room. The insulation colours are visible but only when needed - as the insulation is stripped.

The electrical parameters of DNM Resolution 2, its capacitance, inductance and resistance, are aligned to improve the driving amplifier's stability and sound quality.

The characteristic impedance of DNM Resolution is accurately matched to our optional high frequency termination networks (HFTN's and ZRTNís). HFTN filters greatly improve performance when the cable is connected to amplifiers using negative feedback. They can be added at each end of the cable when the ultimate audio performance is required.

DNM Stereo Solid Core Precision 2 Speaker cable
A flat speaker cable only 2.2mm thick, its small semi-transparent ribbon is almost invisible in the room. DNM Stereo Solid Core Precision 2 has left and right (or bi-wire) conductors in one easily separated ribbon for ultimate electromagnetic performance.
Designed for use with high sensitivity speakers (above 89dB/Watt) and smaller hi-fi systems, DNM Precision 2 is the clearest speaker cable available- in every sense.

DNM Power Amplifiers

PA3 and PA3S - Thinking about amps : class A, valve or transistor - thinking about really high performance power amps? Read this!
PA3 and PA3S Power Amplifiers

In the home hi-fi system big amplifiers sound bad because more power causes loss of resolution, which sounds less powerful! By modern standards non-linear switching amplifiers are not hi-fi.
Before buying a high power amplifier always listen to it at low level close to the speakers, it will sound distorted! Read more here.
