T A M 40 HV Mono Power Amplifier 550 Watts (Titanium)

T A M 40 HV Mono Power Amplifier 550 Watts (Titanium) Key Features T A M 40 HV Mono Power Amplifier in titanium is the ultimate mono power amplifier in the HV series—an uncompromising fusion of tube warmth and transistor power, designed to drive even the most demanding high-end speakers with authority, precision, and musicality. Hybrid high-voltage designCombines a tube input stage (6SN7 triodes in Class A) with a solid-state output stage for a perfect balance of musical warmth and dynamic power. Massive output performanceDelivers 300 W @ 8 ohms, 550 W @ 4 ohms, and peaks beyond 900 W into 2 ohms—handling large speakers with effortless control. Selectable operating modesChoose between Pure Class A operation for smaller loads or High Bias Class AB for higher output demands. Independent dual mono architectureSeparate power supplies and amplification paths ensure total channel separation and superior stereo imaging. Over-engineered power supplyEquipped with a 2000 VA transformer and 240,000 µF of storage capacitance for exceptional stability and transient response. Versatile inputs and integrationBalanced XLR and unbalanced RCA inputs, plus HV-Link for seamless operation with T A HV preamps and systems. Premium German build qualityEncased in a massive aluminum chassis with full electromagnetic shielding for low noise and high reliability. With its hybrid topology, immense power reserves, and elegant titanium finish, the T A M 40 HV sets a new benchmark in mono amplifier design for reference-level high-fidelity systems. The Mono Power Amplifier 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. 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.
