MD209 FM Receiver with DAC and USB

The latest and improved version of Magnum Dynalab's wonderful MD209 Receiver with the optional built in DAC.  This unit has the optional Amber lighting and includes a remote control handset.

From Magnum Dynalab's pedigree in pure analogue circuitry, they've introduced their most uncompromising 2 channel Audio Receiver. Loaded with features, and stocked with Magnum Dynalab's unrelenting build quality and audio engineering, the new MD-209 is a future-ready anchor for your high-performance home audio system.

The simple and efficient treatment of the analogue signal throughout the MD-209 is, without a doubt, the hallmark of this marvelously musical device. Magnum Dynalab's Director of Design, Zdenko Zivkovic, has worked tirelessly to develop the Hybrid-Acoustic design platform, the backbone of this Hybrid Audio Receiver. This distinctive circuit path delivers the unique combination of long tube life (expected to be greater than 7 years under normal use), with high-current output in a design that generates ½ of its gain from the triode stage. The result is reference-quality audio realism and soundstaging of a full triode design combined with the sharp detail and harmonics characterized by the very best solid state devices.

This unique combination of long tube-life and high current output is achieved NOT by the use of output transformers, which add weight, limit frequency response, and ultimately, harm the harmonics of the resultant signal. Rather, the MD-209 is equipped with an output stage that generates power through the use of 20 Sanken output transistors (10 per channel), which amplify current, NOT voltage, taking critical stress off the JJ 6922 Cryovalve tubes, and eliminating the need for traditional output tubes that are typical of tube amplifiers. This allows the Cyrovalve tubes to operate efficiently, and when combined with a collection of world-leading components, including Mundorf Supreme capacitors in the tube gain stage, Kimber Hyper-Pure cables throughout the device and WBT binding posts and Cardas RCA connectors, it's no surprise that the ultimate result is a perfect reproduction of the original dynamic signal from the source component.

Not to be overlooked, they've also equipped the MD-209 with a 650VA power plant that is more than capable delivering current to all critical components. A shielded torroidal transformer and 8 Mundorf electrolytic capacitors delivering a total of 80,000uF of filtration ensures a flat DC supply of power.

RF Section

From a history of world-leading RF designs, we have put our best into the MD-209. An eight stage Varactor tuned front end ensures that this source is unequaled in its ability to receive and replicate a pure FM signal. With two stages of I.F. selection, you can opt for the setting that allows the most authentic, pure listening experience regardless of the reception environment and conditions. The automatic gain control feature insures that the tuner will optimize R.F. performance no matter the strength of the input signal.

As is that case with all Magnum Dynalab FM Tuners, they design and produce their own analogue front ends. This integral core to any tuner is carefully built in-house to meet our rigid standards and specifications, and in addition, great care is taken in matching all critical components, especially the IF filters. This attention to detail for a circuit path that is often overlooked ensures that the FM section of our MD-209 is sure to be a hallmark source for your home audio system.

DAC Section

The highly competent analogue design of the MD-209 2 Channel Audio Receiver necessitated a digital interface board that provided the same high level of performance. This unique circuit design uses two industry leading core components for the receiving and rendering of the digital signal, with the front end of the board driven by the CS8416 192kHz Digital Audio Receiver from CIRRUS Logic, capable of incredibly high performance standards.

Further, Magnum Dynalab have taken special care to feed the I2S signal through only state of the art components, first through the PCM 2707 DAC chip, then the OPA 827 OP AMP, recognized by many in the field as the best available. And when combined with the Texas Instruments PCM1794, 200kHz current output Delta-Sigma over-sampling DAC for audio rendering and the SRC 4192 full-time upconverting/upsampling DSP, the signal is ALWAYS operating at 24 bit/192kHz, ensuring a perfectly clocked, incredibly accurate output that is virtually jitter-free.

The sonic result of this elimination of jitter is immediately recognizable, transforming any digital signal into a focused, clear and accurate signal in the analogue domain. This creates a product that is hugely scalable, allowing the MD-209 to be a true anchor in your home entertainment system.
