XS- Pre 2 technical description Power supply Dual mono with three double shielded transformers with lower radiated and mechanical noise. They also have an electrostatic shield that also keeps more RFI out. One transformer for left, one for the right and then a digital one.
The external power supply
Uses more capacitance and some pre regulators that the previous XS didn’t have. The DC power cable is also improved and uses some very secure military grade connectors.
This is all contained in a new chassis with dual organic LED type displays.
The XS Pre 2 has a new gain circuit that offers higher bias and better stability and lower noise. The circuitry is on plug in circuit boards specific to the XS.
These boards are ceramic based and gold plated, it makes a difference. The transistors used are Toshiba FETS on the input and MOSFETS on the output. We have a nice stash of these purchased before they where discontinued.
The output stage runs a higher class A bias with auto bias and lower output impedance.
After all why would anybody make a pre that wasn’t class A. The XS Pre 2 can drive long cable runs and low input impedance easily. A servo controls DC offset after it is set by hand and balance adjusted. With the new circuit configuration it does very little work. The volume control is single stage with no active gain. It offers 100 dB of range in .5 dB steps.
結局のところ、クラス A でないプリアンプを作る人がいるでしょうか。XS Pre 2 は、長いケーブルと低い入力インピーダンスを簡単に駆動できます。サーボは、手動で設定してバランスを調整した後、DC オフセットを制御します。新しい回路構成では、ほとんど作業を行いません。 ボリューム コントロールは、アクティブ ゲインのないシングル ステージです。0.5 dB ステップで 100 dB の範囲を提供します。

Introducing MSB’s latest innovation: Bit Diffusion Technology. This new technology was invented by MSB’s Chief Circuit Designer, Dustin Symanski, while working on the forthcoming Sentinel DAC project with astounding results. He was able to adapt this into the Cascade DAC with a minor hardware update, but as for the performance gain, this is much more than a small tweak! It is a significant, technological step forward in musicality, resulting in wonderfully natural playback. Dustin’s concept for BDT was initially sparked by considering the relationship between an atom and an electron’s probability density function. Mimicking this natural phenomena, Bit Diffusion is applied to the Cascade’s unique architecture of 16 independent DAC channels. Low-level ambient noise and digital artifacts are diffused, adding to analog-like sound and a much more relaxed, fatigue-free presentation. The soundstage has become more holographic than ever with improved dynamics and separation. Listening to that one recording you know and love so well, thinking you knew every detail, it is shocking to then hear so many new nuances and beautiful moments washing over you. This is just a taste of how the future Sentinel DAC’s 64 channels will benefit from Bit Diffusion Technology, as it takes this concept even further!
We will immediately begin including Bit Diffusion Technology on all Cascade DAC’s moving forward without a price increase. We will also be offering this upgrade for all existing Cascade DAC’s at no charge, except for shipping and handling. To upgrade an existing DAC, just the Cascade Analog Converter unit will need to be returned to the factory for a quick turnaround. This technology will not be adapted to earlier generations of MSB DACs, as only the advanced Cascade and Sentinel hardware is able to support it.
To experience Bit Diffusion Technology, or to have your current Cascade DAC updated, reach out to your local dealer or distributor.
We’re proud to announce the latest innovation from our sister brand, Wattson Audio—a bold new step in performance and musicality that redefines what’s possible at its price point.
Crafted with the same passion for precision and sonic excellence that drives everything we do at CH, this new product is a testament to Wattson’s design ethos: pure, powerful, and purposeful. It’s more than just a product — it’s a gateway to high-end sound, built for those who want uncompromising quality in a beautifully streamlined form.
New Nagra Compact Phono stage, for the love of vinyl
Romanel, Switzerland – 25th March 2025 Perpetuating a long legacy of excellence in phono stages since the Nagra PL-P, the new Nagra Compact Phono offers the greater part of its predecessors’ quality and performance in a compact and elegant housing. The signal path has been simplified to the extreme to offer the quintessence of RIAA correction for the best MC cartridges.
Phono reproduction was at the heart of our very first Hi-Fi product, the Nagra PL-P.
Inspired by the legendary microphone preamplifier in the Nagra IV-S reel-to-reel tape recorder, the phono section of the PL-P received accolades from around the world.
Since then, the phono section of the PL-P has been reincarnated several times with the Nagra VPS, the BPS, the Classic Phono and recently the HD Phono. While they use different technologies and components, they are faithful to the original design, centred around a Nagra-made, step-up transformer.
The latest iteration is the Compact Phono. Housed in the same chassis as the Streamer, its solid construction protects it from unwanted vibrations. No compromises in sound quality were made to enable it to fit in the compact chassis. However, we have simplified the different settings and shortened the signal paths as much as possible. As a result, the Compact Phono offers amazing performance for a fraction of the cost of its competitors.
The Compact Phono features:
Vibration-controlled housing, machined from a solid billet of aluminum
MC input on 10 dB step-up transformer (same as Nagra VPS)
Selected transistors operating in class A
All discrete-component topology
Dual-mono layout
Selectable gain of 62 / 47.5 dB
RIAA curve
100 Ohm load (additional loads available from Nagra dealers)
External 12 V DC power supply
Ultra-high rejection ratio regulators coupled with dual-stage filter on internal power supply
The Compact Phono can be further upgraded to achieve even greater performance using the Nagra MPS or Classic PSU power supplies. In this case, a Lemo to DC cable is required.
To minimize vibration, it can also rest on a VFS or on its own Compact VFS, currently under development.
The Nagra Turntable and cartridges gave us a new benchmark to design the Nagra HD Phono and now the Compact Phono.
Whilst its size and price, for a Nagra product, may mislead you, this is a very ambitious unit and it is fully worthy of the Nagra logo engraved on its front.
Specifications
Frequency response 20 – 50 kHz +/- 1 dB (withing RIAA curve)
Signal to noise ratio* > 80 dB
THD+N < 0.1 % with lab power supply
Crosstalk* > 85 dB
Output impedance* < 10 Ω
Weight and dimensions 1.9 kg (4.1 lb.) 185 x 166 x 41 mm / 7.2 x 6.5 x 1.6 inches

TADL Announces TAD-M2500TX Evolution-Series Power Amplifier Loaded with Upgraded Features and Performance
Technical Audio Devices Laboratories, Inc., today announced the TAD-M2500TX two-channel power amplifier as the newest addition to its Evolution Series of hi-fi audio components.
The TAD-M2500TX power amplifier boasts a completely redesigned circuit layout, upgraded power transformers, and a redesigned machined aluminum chassis, and provides 550 watts of power per channel at 4 ohms. When connected to TAD speakers in the Evolution Series, the M2500TX delivers powerful sound with exceptional clarity, for which every TAD hi-fi component is known.
Main Features
1) Ultimate symmetry in circuitry and layout
Sources of positive and negative currents that go through a speaker unit’s voice coils must be identical to drive its diaphragm with utmost precision. To that end, the TAD-M2500TX employs a BTL (bridge-tied load) design that connects two separate amplifiers in a balanced configuration for the left and right channels in the amplification circuit from input through output stages. In this design, positive and negative power supplies maintain perfect symmetry between them, and all power supply circuits are designed separately for each channel. The redesigned machined aluminum chassis has no joints and helps reduce the impedance of the grounding point that serves as a reference point for symmetry. Our meticulous effort to achieve ultimate symmetry between left and right channels and between positive and negative signals did not stop there. We redesigned the grounding point not only electrically but also structurally, and redesigned the circuit and its layout in the first amplification stage.
2) High-capacity transformers with greater purity and efficiency
The TAD-M2500TX is powered by upgraded twin high-capacity toroidal transformers with a power rating of 1 kVA each. To increase the purity of power supply, the internal coil of the transformer is directly connected to the power supply circuit, minimizing the contact points with leading wires. Moreover, terminals for directly connected coils, mounting terminals for motherboards, and clamping screws are all made of oxygen-free copper coated with nonmagnetic materials to eliminate even the slightest magnetic distortions. The shape of the cross-section of the transformer core has been redesigned to circular in the TAD-M2500TX, from square in its predecessor. The circular design improves contact between the core and coils, minimizing unwanted leakage magnetic flux and vibrations. The result is a power supply with greater purity and responsiveness, contributing to the exceptionally accurate driving of speaker diaphragms.
3) Power rating of 550 watts per channel at 4 ohms
The TAD-M2500TX delivers an incredible 550 watts of power per channel at 4 ohms. This is made possible by the simplified Class-D single-output-stage consisting of power MOSFET devices with ultra-low on-resistance in leadless packages that boast minimum power losses and high-speed responses. Combined with a machined aluminum chassis with superb heat dissipation, the result is powerful yet responsive and agile sound reproduction.
4) Meticulous vibration-control design
TAD-M2500TX’s chassis is machined from a 90 kg solid block of aluminum. Its heavy and joint-free design eliminates an adverse effect of external vibrations and helps stabilize the ground potential and music signals delivered to speakers. The immense body of the TAD-M2500TX is supported by a three-point support structure with internally inverted spikes, which physically isolates its chassis from external vibrations traveling through the floor. The minimum contact with the surface on which the TAD-M2500TX sits keeps external vibrations from traveling through the feet and adversely affecting circuits and parts inside the case. This elaborate vibration-control design results in more condensed and energetic audio reproduction with spatial nuance of the music retained intact. Heavy-duty, extra-large speaker terminals on the rear panel, similar to the ones found in the Reference Series power amplifiers, reduce mechanical and electrical stress on connected speaker cables to improve their stability and bring out the best of them.
5) Bi-amping option
The TAD-M2500TX offers a bi-amping option for compatible speakers. With this option, one TAD-M2500TX can be connected to the tweeter terminals of right and left speakers, and another to their woofer terminals. The bi-amping connection eliminates interference between speaker units and improves their separation. This option brings out the best of amplifiers and speakers, enabling them to deliver sound with exceptional clarity.
TAD-M2500TX specifications
Power Output550 W at 1 kHz, 4Ω
Rated DistortionLess than 0.05% at 1 kHz, 275 W, 4Ω
Signal-to-Noise Ratio112 dB or higher
Frequency Response10 Hz to 50 kHz, +0 dB/-3 dBGain29.5 dB
This is the current-enhanced version of the M-3. It has doubled the current supply capacity without compromising the spatial expression and penetration of the single push, and has succeeded in further expanding the range of profound musical expression.
Parallel push-pull output with precise transistor pairs
厳密なトランジスタペアによるパラレルプッシュプル出力段
Focusing on the curve of change in current gain (hfe) against current change during music playback, we performed strict transistor pairing by aligning this, and realized an ideal parallel push-pull close to a single push-pull. The output stage transistors use a pair of industrial TO3 (metal can type) transistors used in the M-3. In order to easily drive the two TO3 transistors, a TO3P transistor is also used in the driver stage, resulting in a total of four-stage Darlington configuration.
