INTRODUCTION
AN INTRODUCTION OF MAVIS TUBE MOSFET TRANSFORMER MAVIS’s Tube Mosfet Transformer is a hybrid tube amplification product line The hybrid tube amplification includes Master Series and Reference Series. MAVIS’s hybrid tube amplification exploits the emotional sound of the tube and the high power of solid state amplification. This design achieves both wonderful sound quality and an ability of well controlling all frequencies. Therefore, MAVIS’s hybrid tube amplification is extremely a good choice for reproducing all genres of music as correct and natural as possible as well as a great companion for all Hi Fi and High End loudspeakers. Also, with its flexibility and multi-functionality, MAVIS’s hybrid tube amplification brings an outstanding convenience in connecting and combining with many types of player including both analog devices and streamers. This brings to the user a diversity of playing with many types of high resolution music sources. |
DESIGN MINDSET
After a long journey in researching and developing various tube amplification designs from 2006 until today, our target in New Generation hybrid tube amplification design is taking advantage of great achievements of tube amplification designs researched and developed by our R&D team. Accordingly, all engineering applications and combinations of tubes and components are optimized to get the best sound that we define as natural, correct and emotional sound reproduction.
– Zero Feedback
Our designers have seen that many designs of hybrid amplification today are popular with a combination of a tube pre-amplifier and solid stage power amplifier with many amplification stages. This design solution usually uses too much feedback, which reduces the natural and detail of the original sound, making the reproduced sound become hard, dry and less emotional. Using too much feedback for the amplification has more negative results than its benefit for the sound reproduction. Therefore, in the MAVIS’s Master Series hybrid tube amplifiers, we limit maximum feedback in amplifying to achieve the most natural and correct sound.
Indeed, Zero Feedback is one top of our criteria when designing amplifiers. This engineering method preserves the naturalness of the sound, so that the music is conveyed most faithfully and emotionally.
– Using Output Transformer and Interstage Transformer in hybrid tube amplification
Output Transformer (OPT) and Interstage Transformer (IT) are always known as a very high cost component that is often used in high end tube amplifiers. This component is also the best choice in tube amplification design to get the most natural and high fidelity sound quality. In the world at present time, the MAVIS’s Tube Mosfet Transformer amplifiers are the unique hybrid tube amplifiers using both OPT and IT. Our technology of OPT and IT has been researched and developed for many years since 2008 until now and these are the very important components that contribute to the best sound quality of our all tube amplifier and hybrid tube amplifier today. Our OPT and IT are made in-house by the highly skilled technicians.
ENGINEERING SOLUTION
The Integrated Amplifier realizes many features that many Audiophiles dream of, which are often considered impossible:
The M90 combines the best capabilities of a top-notch solid-state amplifier with the rich and colorful flavors of sound that only a Single Ended Tube Amplifier design can create.
MAVIS M90 is an Integrated Amplifier with Hybrid design combining Tube and Solid-state amplifier to exploit all greatest features of both.
– Tube – electronic vacuum tube – is very famous for its thick, warm, detailed and highly musical sound. The Driver stage uses 12AU7 tube and EL84 power tube with Single Ended – Class A transformer to optimally transmit the flexibility and sophistication of vacuum tubes to the solid state power stage.
– The combination of a solid state power amplifier creates high dynamics, controls the speaker drivers well, enhances the bass response quickly and is extremely detailed, clean. These results give the M90 a powerful, well-controlled bass range, a very quiet, pure and clean musical sound.
The mid and high ranges of the M90 are very detailed, delicate and soaring, the fantastic sound characteristics that only Single Ended Tube Amplifiers can create.
The M90 brings to the users a diversity of changing hundreds of 12AU7/ EL84 tube types in the market. This great feature allows the users to change the tubes to experience many different nuances of sound in an extremely interesting way – A dream for pure Solid-state amplifier Amplifiers!
