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.

SMSL PL200T – CD transport with USB DSD streaming support
SMSL presented the SMSL PL200T CD transport – the highlight of the model was the proprietary SMSL PASS Servo system, which ensures very accurate reading of information from optical media. The SMSL PL200T also has the ability to play MQA-CDs and a very interesting function of working as a digital transport - the device can be used as a digital interface with a USB-C input, supporting digital streams in PCM format with a resolution of up to 32 bit/768 kHz and in DSD format up to DSD512.
Børresen Unveils Six New Floorstanding Speakers in T Series
Børresen has announced significant changes to its range of loudspeakers - the new Børresen T series of loudspeakers, consisting of three models of different sizes (T1, T3 and T5) and three upgraded SSE (Silver Supreme Edition) versions, will replace the Børresen 0 series in the company's product range.
Accuphase A-48S – Current Feedback Topology Amplifier
The current feedback amplification topology and powerful power supply of the new Accuphase A-48S amplifier provides a large reserve and stable output in pure Class A. For a load with an impedance of 8 ohms, 50 watts are available, and halving the load impedance doubles the output power. With a short-term drop in load impedance to 1 ohm, the amplifier is capable of delivering a power of 400 watts.
Remton audio 481 MK2 – a Tube Phonostage Based on NOS Tesla Resistors
The Czech audio equipment manufacturer Remton Audio has introduced a tube (4 x JJ ECC81) phono preamplifier with Remton audio 481 MK2 Limited edition – this approach is explained by the use of NOS Tesla resistors with a deviation of only 0.25 dB in the range from 20 Hz to 50 kHz. These resistors are quite rare, so the circulation of both the first and second versions of the phono preamplifier is limited.
TOTALDAC d1-CD – Top-Loading Compact Disc Transport
French company TOTALDAC has released the d1-CD CD transport, the “ultimate solution” for High End disc-based systems. The TOTALDAC d1-CD transport is based on the top-loading CD-PRO8 drive, and also features separate clock generators for the drive and audio outputs, as well as an intelligent ground distribution system.
