Tube-Solid State Receiver with Built-in DAC
Building upon a pedigree in pure analog circuitry, Magnum Dynalab's two-channel MD-209 receiver offers uncompromising performance. Loaded with features while boasting premium build quality and audio engineering, the MD-209 is a future-ready anchor for a high-performance home audio system.
With one line-level pre-amp output, two balanced (XLR) inputs, and three single-ended analog inputs (including a surround sound processor input for integration with multi-channel applications), plus three digital inputs (including USB), the MD-209 has all the flexibility you need.
The MD-209's unique and proprietary Hybrid-Acoustic circuitry combines the musicality, soundstaging, and audio realism of the company's 6922 CryoTubes with the crisp detail, harmonics, and long life of a solid state device.
The simple and efficient treatment of the analog signal throughout the MD-209 is, without a doubt, the hallmark of this marvelously musical component. Magnum Dynalab's Director of Design Zdenko Zivkovic has worked tirelessly to develop the Hybrid-Acoustic design platform as the backbone of this receiver.
This distinctive circuit path delivers the unique combination of long tube life (expected to be greater than seven years under normal use) with high-current output in a design that generates one-half 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.
Sophisticated Solid State Output Stage
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. Instead, the MD-209 is equipped with an output stage that generates power through the use of 20 Sanken output transistors (10 per channel). These amplify current, rather than voltage, taking critical stress off the 6922 Cryovalve tubes and eliminating the need for traditional output tubes.
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, along with WBT binding posts and Cardas RCA connectors -- the result is a perfect reproduction of the original dynamic signal from the source component.
Formidable Power Supply
Magnum Dynalab has also equipped the MD-209 with a 650VA power plant that is more than capable of delivering current to all critical components. A shielded torroidal transformer and eight Mundorf electrolytic capacitors (delivering a total of 80,000uF of filtration) ensure a flat supply of DC power.
'Historic' RF Section
Drawing upon its history of world-leading RF designs, Magnum Dynalab has put its best work into the MD-209. The eight-stage Varactor tuned front end is unequaled in its ability to receive and replicate a pure FM signal. Two stages of I.F. selection let you choose the setting that allows the most authentic, pure listening experience, regardless of the reception environment and conditions. The automatic gain control feature optimizes R.F. performance no matter the strength of the input signal.
As with all Magnum Dynalab FM tuners, the company designs and produces the analog front end. This integral core to any tuner is carefully built in-house to meet Magnum Dynalab's rigid standards and specifications. 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 the MD-209 is sure to be a hallmark source for your audio system.
Advanced DAC Section
You can integrate the digital stream of any digital source component with the MD-209, thanks to its advanced DAC. It features magnum Dynalab's upconverting and oversampling Burr-Brown design, three digital inputs (including USB), and seamless operation through the remote or faceplate.
The no-compromise analog design of the MD-209 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.
Magnum Dynalab has taken special care to feed the I2S signal through state-of-the-art components, including the PCM 2707 DAC chip, then the OPA 827 OP AMP, recognized by many in the field as the best available. These are combined with the Texas Instruments PCM1792, 200 kHz current output Delta-Sigma over-sampling DAC for audio rendering, plus the SRC 4192 full-time upconverting / upsampling DSP. As a result, the signal continuously operates at 24-bit, 192 kHz, ensuring a perfectly clocked, incredibly accurate output that is virtually jitter-free.
More, More, More
The bright LED display, symmetrical knobs and meters, and a 3/8" thick faceplate, make the MD-209 as attractive as it is easy-to-operate.
A proprietary circuit runs regular diagnostics, ensuring safe and efficient operation of the unit at all times and safeguarding against any unwanted current that may harm your speaker.
The sonic result of this elimination of jitter is immediately recognizable, transforming any digital signal into a focused, clear, and accurate signal in the analog domain.
