Pier Audio MS 1000 SE – Integrated Amplifier With Tube Rectifier
02.03.2025 06:27 | ~2 minutes read
French company Pier Audio presented the integrated amplifier Pier Audio MS 1000 SE. The model uses a large-sized 800 VA power transformer wound in the old style with high quality copper and weighs 23 kg. Up to a power of 2 x 20 W per channel, Pier Audio MS 1000 SE operates in class A, then switches to class AB, developing up to 2 x 150 W at 8 Ohm load and doubling the power to 2 x 300 W at 4 Ohm speakers.
The amplifier is built on a hybrid circuit - the preliminary amplification stages are made on tubes (6SN7 x 2, 6N11 x 2, rectifier 6Z4 / 6U4 x 1), and the output ones are on transistors (Sanken x 8). The Pier Audio MS 1000 SE model differs from other hybrid amplifiers by using a tube rectifier for the input tubes based on a double diode 6Z4 or 6U4. In the center of the front panel there is a large pointer signal level indicator.
The Pier Audio MS 1000 SE commutation capabilities include two unbalanced line inputs on RCA connectors and an input of a built-in phono preamplifier for moving magnet (MM) cartridges. There are no digital inputs here, but the amplifier supports Bluetooth connection using the supplied antenna. There is also a direct pre-in power amplifier input. Volume control is carried out using a motorized potentiometer from the renowned manufacturer ALPS.
The Pier Audio MS 1000 SE hybrid integrated amplifier is available for sale at a recommended retail price of 2,990 euros.
