T+A M 40 HV Power Amplifier

The M 40 HV utilizes a hybrid design that combines the classic warmth of 6SN7 valves in the input stage with a high-voltage J-FET transistor output. This approach provides the musicality and harmonic richness of tubes while maintaining the power and control of a high-performance solid-state amplifier.

The M 40 HV delivers a robust 550 watts into an 8-ohm load. This significant power output ensures it can drive even the most demanding, low-sensitivity loudspeakers with ease and authority.

While the M 40 HV features both XLR and RCA inputs for broad compatibility, it is specifically engineered to integrate seamlessly with T+A’s HV-series components. Using it within the HV ecosystem ensures the best possible signal path and sonic synergy.

Due to its substantial 52kg (114.64 lbs) weight and large dimensions, you must ensure your equipment rack or stand is rated to support heavy high-end audio components. We recommend a sturdy, stable surface to accommodate its size and mass.

The 6SN7 valves are used in a symmetrical differential circuit to provide a more natural, fluid, and harmonically rich sound. This design choice helps eliminate the clinical or sterile edge sometimes associated with high-power solid-state amplification.

Yes, with a frequency response extending from 1Hz to 150kHz and an exceptionally low total harmonic distortion of 0.009%, the M 40 HV is designed to resolve the finest details in high-resolution recordings. It is built to maintain signal integrity across a very wide bandwidth.
