MAVIS M 60P Standart version Tube Mosfet Transformer Integrated Amp.

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.

– Assembling the hybrid tube amplifier by Point-to-Point method

Point-to-point is a very high cost method of assembling amplifiers because this method requires a lot of labour time and high skilled technicians. In return, the advantages of this method are the great durability and stable operation of the device so this method is often applied in producing high end tube amplifiers. Mavis’s all Tube Mosfet Transformer Amplifiers are assembled by point-to-point and this is an outstanding standard for the MAVIS’s hybrid tube amplifier.

ENGINEERING SOLUTION

The M60 is a high power hybrid tube amp model with very good sound control. The M60 uses an Output Transformer (OPT) and an Output Transformer (IT) in the amplifier circuitry as the same as other hybrid tube amp models in the MAVIS’s Master Series. This is the most prominent and distinctive solution in the electronic design of the MAVIS’s hybrid lamp amplifier. The OPT built for the M60 is quite big and heavy, so the sound is really quiet and clean, warm and sweet. The sound is very emotional and natural like the typical sound of the tube amplification. Moreover, the tonal ranges are reproduced very fully, with high dynamics and details. Bass is very well controlled. This model can well control low-sensitivity speakers below 90dB in small and medium-sized listening rooms. With speakers with a high sensitivity of over 90dB, the M60 can even play well with the loudspeaker having a large bass driver and in listening rooms up to 100 square meters.

– Driver Stage:

– The input and voltage amplifier stages use all 12AU7, EL84 tubes which are the best tube combination for the smooth, sweet and warm, emotional and natural sound. The voltage amplification using electronic tubes works in Class A Single-ended with an operation mode designed with a different mindset to combine the detailed, soaring sound of the first stage 12AU7 tube and the warm, seductive sound of second stage 12AU7 tube. The audio signal after passing through these stages is polished cleanly and smoothly.

– EL84 tube, a small power tube known for its distinctive warm sound, is used to amplify the current and control the power stage. Therefore, the sound is extremely seductive and emotional.

– Interstage Transformer (IT) and signal phase inversion is used to link the EL84 driver stage and Mosfet power stage. This way has the advantage of isolating the driver stage and power stage, making the stages operate separately and stably. IT is the optimal solution for the most stable and almost absolute balanced signal. In addition, using IT is always the top choice of experienced designers to achieve the finest quality of the musicality.

– Power Stage:

– Using Input-to-Output Balanced Circuit is the advantage of this design, which is excellent stability, low noise and very low distortion.

– To limit the reduction of signal by using too many components, only two Mosfets are used for the power stage circuit.

The sound is more clean and detailed when the speaker output is True Balanced, so the two speaker terminals (+) and (-) are not connected to the Ground (GND) of the power supply.

A FEATURE OF SOUND MODE SELECTION

After a process of studying and experiencing real live music as well as through our research projects on amplifying the live music performances on high-end sound systems, recording and producing music, we find that music genres are really diverse and each genre will have its own characteristics of musicality and sound. In addition, depending on the culture, the specific music genre of each different culture, the listener has a difference in listening habits. Also, depending on the listeners age, music experience and personal favourite of music genres, the music need and sound taste of each listener will be different from the other. Indeed, each person will have his or her own needs in enjoying the music.

Accordingly, in addition to the sound that is reproduced properly and naturally by our sound philosophy and standards, some customization features are added to give the user an opportunity to choose the right sound mode to match the music genres, preferences, listening room conditions and combined devices to bring the most satisfying music experience to listeners. The users have complete flexibility to choose according to their personal preferences for their music and listening conditions.

 OPTIONS 

The M60 was developed with MAVIS’s goal in mind to maximize the music experience with a flexibility in terms of product functionality, usage and appearance. Accordingly, the M60 has up to FIVE options of UPGRADE versions based on the standard version so that users can choose the right one for their personal needs and music experience. These are the outstanding features of MAVIS’s Tube Mosfet Transformer amps. Diverse integration versions provide extremely useful customization and flexibility for different listening needs of users, and are easy to combine with existing equipment in the sound system.

M60 Versions

FLEXIBLE DECORATION  επιπλέον 240 ευρώ.

M60 has a modern and eye-catching appearance with two VU on the front of the amp. This is a very nice product design with a combination of a little classic and modern elements. Tube replacement is also easy with the convenient removable front cover. The transparent tube protection front plate helps users observe the operation of the tubes as well as see their beauty.

The product also has an additional option of decoration outside the amplifier chassis. The amplifier can be decorated with wooden plates on two sides of the amp chassis. They can be flexibly attached to the sides of the amplifier with magnets.
