Overview

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.

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 harmonizes 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.

About T+A

For Generations We are a family company, managed by its proprietors. If we pose the question: why is T+A equipment so special? Then we find the answer in the following situation: we grant ourselves the freedom to implement our convictions; to focus on decades, rather than just the next quarter. It is precisely this independence of action which enables us to accomplish long-term goals. For example, we took three years to develop the first device in our HV Series, and it was perfect. Our company founder loves music and technology, believes in science and the laws of physics, and always aimed to push those limits as far as possible; every single T+A device incorporates those convictions. These values will continue to be our companions for generations to come. At the same time the principles of our family enterprise are also reflected in our support for the coming generation.
