Nagra Reference Preamp – High End in the flesh
20.12.2024 08:20 | ~1 minute read
Nagry has introduced a new Reference Preamp, of the top series. The flagship model of the famous High End equipment manufacturer promises incredible sound quality. The company has not yet made detailed specifications public, but the most important features of the Nagra Reference Preamp are already known.
They are as follows:
– a significantly improved audio signal chain, including the use of special capacitors in the circuit;
– use of new generation high-voltage power supplies generating 200 V DC mains voltage, increased filter capacity in the main power supply;
– mechanical damping of the case with the addition of a phenolic layer in the top panel;
– optional ability to use up to two external power supplies: one for the audio signal section, the second for the controls and switching elements.
The Nagra Reference Preamplifier, as well as the proprietary DAC and phonostage, can operate from a single power supply. Starting with one power supply, a second one can be added later to achieve unprecedented sounds.

Matrix Audio NT-1 and TT-1 – New Upper Echelon Network Streamers
Matrix Audio has introduced two new network streamers with transport functionality – devoid of a digital-to-analog converter and designed for use with external DACs. Both models are designed in a recognizable futuristic aesthetic and are equipped with large touch screens on the front panel. The streamers are also Roon certified.
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.
