DNM

Founded in 1978, DNM is a reputed manufacturer of amplifiers, cables and other hi-end audio equipment. Through adequate investment in research and development, the company has garnered a loyal fan following among professional musicians and sound engineers as well as music enthusiasts. One of the key features of DNM amplifiers was the usage of high-quality acrylic in the amplifier jackets. This material is known to be a good insulator and also offers minimal interference with audio signal transmission.

A flat-panel design lowered the microphony and made the resonance sharper. In 1984, DNM pioneered the manufacture of solid core speakers and interconnect cables. Alongside battery-powered pre-amplifiers, DNM also produced amplifier power supplies. DNM also deserves credit for inventing the electrolytic slit foil capacitors that prevent undue distortion in the current flow. Some other products offered by DNM include pickup cartridges, pickup arms, turntables, heat sinks, equipment stands and volume controls.

Another first from DNM is the incorporation of a 3-dimensional circuit layout with controllable magnetic field effects. DNM transistor amplifiers are known to offer better performance than even single-ended valve devices. The usage of impedance-functioning sound circuits result in enhanced resolution and also lowered high-frequency reflections. DNM has always strived to increase efficiency in circuits using minimal components. The company stresses on the fact that most of its employees are music fanatics and this enthusiasm shows in the quality of its products.
