MD-107T Tube Tuner

MD-107T Tube Tuner
New for 2010, the MD 107 FM Tuner is a worthy replacement of one of our long-standing flagship products, the MD 106T. Now standard on many of our high-performance tuners, the MD 107 uses two 6922 MD Triodes in the audio amplification stage, and features upgraded capacitors, tighter tolerances on components in the RF section, and an improved power supply. It also comes equipped (as an option) with our onboard DAC, with available S/PDIF and USB 2.0 inputs, both of which are selectable via the optional remote or the faceplate. For more information on our DAC upgrade, Consistent with our design philosophy to separate the analog R.F. section and the audio section, the MD 107 FM Tuner treats the incoming RF signal with special care.
The analog front-end of this tuner is 100% in-house designed and manufactured, using five stages of RF filtration with precise hand-matched components in the critical areas. A key component in any FM tuner, the front end is of most importance to maximizing sensitivity and selectivity while minimizing distortion, ensuring the signal sent to the audio section is as pure as possible. There is no other company world-wide that still manufacturers their own front-end, nor is there a company that we can count on to deliver an RF front end worthy of inclusion in our tuners.
Not to be forgotten, the MD 107 is built around the unique Magic Eye Tuning meter, providing an accurate and elegant tuning mechanism to ensure the perfect frequency is fed through the tuner's front end.
Overall, the stately symmetry of the MD 107 is characteristic of the industrial design of all Magnum Dynalab products, and is a visual complement to the outstanding sonic clarity, definitive sound staging and raw finesse of a truly fine audio product.
Primary RF Highlights
Tunable five stage ANALOG front end: Five stages of RF filtration, providing station separation without affecting stereo separation. As always, the front end is a custom designed and manufactured in-house design.
Upgraded Components: Tighter tolerances on all RF filters, improved capacitors and a beefed up power supply are all improvements over the 106T. We've ensured that only the best components from world-leading suppliers are built into the 107.
Magic Tuning Eye: Embedded in faceplate for the most precise and accurate center tuning
Multiple Bandwidth Settings: The MD 107 FM Tuner offers both Ultra Wide and Narrow IF Bandwidth settings to produce the best SOUND where adjacent channel interference is, or is not a factor.
Dual AGC (automatic gain control) stage: This automatic circuit design eliminates the need for a local and distant switch, altering the amount of relative gain that's added to the incoming signal.
Auto Blend RF Circuit: Automatically monitors and adjusts stereo separation to maximize "stereo quieting", insuring the quietest stereo signal as possible. This greatly eliminates background noise.
Precision tunable matched IF (intermediate frequency) amplifiers -- ensures consistent specifications for adjacent channel separation, alternate channel separation and low distortion
Precision Voltage Stabilizers in the Power Supply: Ensures precise tuning of the incoming RF signal
Defeatable Mute: Eliminates any interstation noise while tuning
Analog Meters: Functional and easy-to-read multipath and signal strength measurements have been upgraded on the 107, using the same precision meters that are found on the 108T.
Fully shielded RF section-eliminates any interference from stray signals

Audio Stage & Power Supply
To complement this world class R.F. section, our proven world-class triode audio section is designed to perform at the same high level our customers have come to expect from Magnum Dynalab products. Specifically, we have paid special attention to three critical areas of the design.
  • First and the most important, we achieve a complete grounding circuit to remove all stray ground path signals that alter the micro-information as it moves through the device, allowing the listener to grasp the full emotion of the music.
  • Secondly, the design of the power supply utilizes a special path and high-grade components, which eliminates any ripple effect from the AC source that would interfere with the nuances in the music.
  • Lastly but no less important is the zero feedback design that does not alter the original waveform. Our design team consists of music lovers, and the design in the 107's audio section allows our customers to feel the same passion for the music as the creator of the original recording.
  • In addition to our primary design criterion, the MD 107 FM Tuner features a variety of design features in the audio stage and power supply that complement the R.F. section. It is a product designed and manufactured with great precision and care, with specific standards for all components included in the device. Whether it is the exacting specifications required for each MD Reference Cryovalve 6922 tube, or the specific thickness of each circuit board inside the device, the MD 107 FM Tuner is an audio product for the most discerning of customers.
Audio Stage & Power Supply HighLights
MD Reference 6922 Vacuum Tubes: Included in the audio amplification stage, our 6922 MD Reference Cryovalve Tubes are designed to our exacting standards and tested individually for specifications.
.093 Thick Printed Circuit Board: A solid footing to minimizes any residual vibration in the chassis to allow all components to operate at peak performance. Further, all contact points are generously gold plated to ensure complete signal transfer over the long haul.
Balanced Output with Gold Plated Neutrik Connectors: Fully complimentary circuit insures a perfectly balanced signal, and exact dimensions ensure maximum conductivity.
Shielded Torroidal Transformer: Coupled with a high grade aluminum chassis, device is completely shielded from stray signals and transient noises. The high grade custom designed transformer has been upgraded in the 107, further reducing the overall noise floor of the tuner.
Mundorf Supreme Capacitors: Used in the bypass, creating sound purity consistent with the original signal.
WBT Unbalanced (RCA) Output Connectors: Low tolerance connector made of highly ductile "OFC" copper, and 24 carat gold plated ensures a solid contact for interconnects
Ultra Linear Capacitors in the Power Supply: Provides a pure source of DC power, and improves the frequency response of the tuner
Kimber Hyper-Pure Copper Wiring: High grade internal wiring provides a clean, uncolored path for the signal through the audio stage of the unit.
Burr Brown Op Amps with Black Gate Capacitors: Proven performance from industry leading suppliers with zero degradation over the long haul
Why Analog ?
Many people question why we are one of the only companies that continue to build a truly ANALOG FM tuner and ANALOG remote control. The answer is very simple. The best SOUND can only be produced when the signal received by the tuner is tuned and maintained in the ANALOG domain. By maintaining the signal in the ANALOG domain the customer has infinite tuning across the FM band; this is achieved by the use of a knob instead of the pushbutton step function tuning offered by a digital tuner. Because of our design and manufacturing process, the front end and the IF (intermediate frequency) amplifiers are precision aligned, which guarantees that all specifications are met all the time; this is not possible in a digitally tuned tuner, as they are dependent on the tolerances of the components. By calibrating and aligning the IF (intermediate frequency) amplifiers we are optimizing SOUND, SENSITIVITY and SELECTIVITY.
