Designed for the Purist: Clean and Integrated Structure
Resonance characteristics of the chassis dominate the eventual sound quality of audio equipment. With this in mind, and with 25 years at the leading edge of audio innovation, we simplified the structure of the MTB-4 and MTB-6 to a minimum in order to avoid internal resonance - since every little component has its own resonance frequency.
We also conducted extensive research in selecting perfect materials for each section, together with detailed analysis of component compatibility, even down to the screws and washers. We went even further to harmonize the components by applying our own proprietary heat treatment process to each and every part.
Together with our own internal wiring system and original super receptacles, we have realized the ultimate power distribution system for Audiophiles.


Main Chassis 

2.0mm thick brass plate formed into a special shape for rigidity, speed and good internal energy absorption properties. The plate is coated with extra thick layers of non-electrolytic nickel ground plating, and then finished with chrome plating to further enhance its rigidity and speed characteristics. This also has the effect of improving shielding against wider range E.M.I. 

Available to the DIY enthusiast and manufacturers alike is the MT-UB Chassis with a choice of IEC inlet or cable clamp hardware for direct wiring.
Internal Wiring
2.0mm dia., high purity (4N) solid Silver, extensively annealed in low temperature to remove mechanical distortion/stress from the extrusion process. We then apply a further highly controlled process in order to produce a smoother and stronger surface for distortion free electron transmission. This also has the effect of eliminating any mechanical weakness caused by the annealing process.
These carefully developed processes enable the Silver to break through to a new level of sound quality. This is further enhanced by independent internal connection to each outlet in order to avoid cross-talk and to ensure evenness. All connections are Lead free.

Further Resonance Control
The main body/insulator is made of Nylon with glass filler mixed in; this ensures high heat resistance, rigidity and a high resonance absorption factor. We also avoided common rubber feet, instead using 4 Brass spikes which can easily be changed to a 3 foot configuration by relocating them. 

Electrical Contacts (Receptacle)
We tested every possible option for this crucial part and concluded that highly polished deoxidized Phosphor Bronze would be optimal as a base material to provide the most secure and least resonant contact. The finishing touches, which determine the final sound quality, are to directly apply an extra thick (1.5 micron) Silver directly to the Bronze substrate, polish the surface twice and finally apply a layer of Rhodium (0.3). This process is strictly controlled for optimum balance and quality of sound. These contacts are supported by 24K Gold plated non-magnetic brass fittings. 

Electromagnetic Interference Control
The mains inlet area is protected by an EMI absorbing layer.

The importance of high quality power supply connections is now widely accepted. Many enthusiasts install dedicated power lines for their hi fi systems and no longer question the importance of the quality of the receptacle fitted to the wall. Conventional "hospital grade" connectors can improve the strength of the mechanical connection, but they are far from ideal for realizing the best sound quality. 

Our objective was to develop receptacles whose sole purpose was to deliver the highest sound quality possible. Every part has been designed with this in mind. Extensive research into the effects of plating methods has yielded three equally valid but different types of sound for you to choose from. The entire series is non-magnetic to avoid any disturbance from magnetic fields.
