T+A M 40 HV Mono Power Amplifier
24000,00 €
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.
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.

T+A (Theory + Application) is a German audio brand known for reference-grade engineering, clean industrial design and an uncompromising approach to sound. T+A builds complete systems — from integrated amplifiers and power amplification to DACs, network players and loudspeakers — with a strong focus on low noise, precision and long-term reliability.
Hi-Fi Market is an authorised T+A dealer in Estonia, supplying genuine products with official manufacturer warranty and local support. We help you choose the right T+A direction for your room and listening habits — whether you want a one-brand system approach or you’re matching T+A electronics with carefully selected speakers and sources.
Visit our showroom near Tallinn (Tabasalu) to audition selected T+A components and discuss real-world setup considerations before you decide.
Build a Stereo System with T+A
T+A works especially well when you think in a complete chain: start with an integrated amplifier (or pre/power), add a network player and DAC as needed, then match stereo speakers for your room size and listening distance.
