T+A Audio M 40 HV Power Amplifier

The hybrid design combines the harmonic richness and musicality of a Class-A tube input stage with the raw power, speed, and control of a high-voltage solid-state output stage. This allows the amplifier to deliver a refined, natural sound without sacrificing the dynamic agility required for demanding speakers.

The M 40 HV is a powerhouse, delivering 550 watts into 8 ohms and a massive 1,000 watts into 4 ohms. This high current capability ensures it can drive virtually any high-end loudspeaker with ease and authority.

The M 40 HV uses two 6SN7 tubes in the input stage, which are known for their longevity and reliability. While they are high-quality components, they are integrated into a sophisticated circuit designed for stability, meaning you do not need to worry about constant maintenance or frequent tube replacements.

Each unit weighs 115 pounds and measures 22 inches in height, so you will need a very sturdy, dedicated equipment rack or a dedicated floor space. Because of its weight and thermal output, ensure your placement allows for adequate ventilation to keep the internal components operating at their peak.

The thermal processor constantly monitors the temperature of the output stages to ensure they remain within the ideal operating range. This prevents overheating during intense listening sessions and helps maintain consistent sonic performance regardless of how hard the amplifier is being pushed.

A monoblock design provides a completely independent power supply and amplification circuit for each channel, which eliminates crosstalk and interference between the left and right signals. This results in superior channel separation, a more expansive soundstage, and improved imaging precision.
