Overview

The M 40 HV provides our HV-series High-Res players and pre-amplifiers with an extremely unique, uncompromising power amplifier which satisfies the most extreme audiophile demands under a vast range of operating conditions. Of course, it can also be used to form the perfect power amplifier for any other High-End set of equipment. One thing we have learned in our forty-year history is that the world of electro-acoustics does not permit a single perfect solution to all requirements; instead every overall design philosophy offers its own strengths and weaknesses. And that is why we have consistently developed optimum solutions for each requirement, whether it is based on valve technology or the very latest form of digital signal processing.

The M 40 HV combines our experience in the various areas of High-End audio technology: audiophile valve construction for the input stages, High Voltage technology for the transistor stages, intelligent thermal processor control for the output stages together with our usual uncompromising case design and construction.

About T+A

Ever since 1978 our driving force has been curiosity. Our aim was to define the framework of the possible, and push its limits a little further each day, and that’s what formed the stone of this company. We always aspired to the creation of new findings rather than the exploitation of existing knowledge. We were determined to carve out our own advances, and not simply follow the progress of technology. Satisfying this goal requires our team of fifteen designers and developers to create every device in our headquarters in Herford. From the initial design, developing every single circuit board and finishing with the software code - the stage which brings all the component parts together to form a grand ensemble - our devices are built in Herford. They are permeated by the belief on which this company was founded, and which drives all of us forward every day. We don't build mass products, we build accoustic treasures, we build heartbeats, goosebumps and enthusiasm.

Features

Valve Technology
To achieve all this we have equipped our finest power amplifier with a circuit design which is unique in the world, combining classic analogue techniques, valve technology, High Voltage amplifier design and intelligent parameter control. The entire input amplification section is based on carefully selected High-End valves of the 6SN7 type, operating in Class-A mode. This results in a very harmonious sonic image, and instils the musical and tonal advantages of valve technology in the sound character of the M 40 HV.
Amplifier Concept
The input stage is designed as a symmetrical differential amplifier exploiting an all-valve cascode circuit. The subsequent voltage amplifier stage is a High Voltage (HV) J-FET amplifier circuit with triode performance characteristics, which also operates in pure Class-A mode. The result is excellent bandwidth and an agile performance which defines the sound qualities of the amplifier as a whole. At the input side the current amplifier stages are based on MOSFET driver transistors whose performance curve harmonises superbly with the HV voltage amplifier stage. At the output side the current amplifiers are equipped with no fewer than twenty extremely high-performance ring emitter bi-polar transistors. These components satisfy the most extreme demands in terms of current supply capacity and bandwidth.
