MD 309 Integrated Amplifier: from our pedigree in pure analog circuitry, we're proud to introduce our most uncompromising 2-channel Integrated Amplifier. Using the same Hybrid-Acoustic CircuitryTM found in our MD-209 Audio Receiver, JJ 6922 Cryovalve tubes, and stocked with Magnum Dynalab's unrelenting build quality and audio engineering, the new MD 309 is a future-ready anchor for your high-performance home audio system. We believe it is the best Integrated Amplifier on the market.
The simple and efficient treatment of the analog signal throughout the MD-309 tube Integrated Amplifier is, without a doubt, the hallmark of this musical device. Our Director of Design Zdenko Zivkovic has worked tirelessly to develop the Hybrid-Acoustic design platform, the backbone of this Hybrid Integrated Amplifier. 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 (225 watts into 8 ohms and 450 watts into 4 ohms) in a design that generates 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.
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-309 Integrated Amplifier is equipped with an output stage that generates power through the use of 40 Sanken output transistors (10 per phase 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 tubes to operate efficiently, and when combined with a collection of world-leading components, including Mundorf Gold capacitors in the tube gain stage, Kimber Hyper Pure wiring throughout, and a unique audio stage that delivers the signal fully balanced before the output stage, the ultimate result is a perfect reproduction of the original dynamic signal from the source component.
The highly competent analog design of the MD-309 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 DAC (Digital Audio Receiver) from CIRRUS Logic, capable of incredibly high performance standards.
Further, we 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 PCM1792, 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 analog domain. This creates a product that is hugely scalable, allowing the MD-309 Hybrid Integrated Amplifier to be a true anchor in your home entertainment system.
