The Phono Box S2 Ultra is a high-quality phono preamplifier designed for audiophiles seeking exceptional sound reproduction from their vinyl records. Its advanced design and premium components make it a valuable addition to any high-fidelity audio setup.FeaturesFully Discrete CircuitryHigh-End ComponentsCustomizable Cartridge Compatibility (MM/MC)Precise RIAA EqualizationDurable and Interference-Resistant DesignDiscrete Design for Superior SoundUnlike many preamplifiers that rely on operational amplifiers (Op-Amps) the Phono Box S2 Ultra employs a fully discrete design. This approach enhances audio performance delivering a cleaner and more detailed sound that brings out the nuances in your vinyl collection.Premium Components Enhance Audio QualityThe inclusion of audiophile-grade polystyrene capacitors often considered the 'holy grail' for phono preamplifiers significantly contributes to the unit's clear and precise sound reproduction. These components ensure that the audio signal remains pure and uncolored.Versatile Compatibility with Various CartridgesWith adjustable gain load and capacitance settings the Phono Box S2 Ultra accommodates a wide range of moving magnet (MM) and moving coil (MC) cartridges. This flexibility allows users to fine-tune the preamp to match their specific cartridge optimizing performance and ensuring the best possible listening experience.Accurate RIAA EqualizationThe preamplifier features precise split RIAA equalization which accurately reproduces the RIAA curve. This accuracy is crucial for faithful playback of vinyl records as it ensures that the frequency response is true to the original recording.Robust Construction for Interference ProtectionHoused in a solid metal casing made of aluminum and steel the Phono Box S2 Ultra is well-protected against electromagnetic interference. This robust construction not only enhances durability but also contributes to the overall sound quality by minimizing noise and signal degradation.Additional Fe

The Phono Box S3 B is a high-quality phono preamplifier designed to enhance your vinyl listening experience. Its balanced and discrete circuitry ensures superior sound quality making it an essential component for audiophiles seeking to elevate their analog audio systems.FeaturesBalanced Connections for True High-Fidelity SoundDiscrete Circuitry for Enhanced Audio DetailSemi-Passive RIAA EqualizationWide Cartridge CompatibilityRobust Elegant Build QualityEnhanced Design and Build QualityHoused in a new larger steel and aluminum chassis the Phono Box S3 B offers increased rigidity and effective isolation from external interference. Available in silver and black finishes it seamlessly integrates into any hi-fi setup.Balanced Connections for Superior SoundThe 'B' in Phono Box S3 B stands for 'Balanced.' It supports balanced connections allowing you to upgrade to true balanced operation with a moving coil (MC) cartridge on most Pro-Ject turntables. Balanced transmissions utilize both hot and cold (positive and negative) signals effectively carrying identical musical information. A true balanced gain stage extracts the final musical details from these signals while minimizing hum and noise a technique commonly used in professional recording studios.Discrete Circuitry for High-Fidelity AudioThe gain stage of the Phono Box S3 B features a fully discrete layout meaning it is composed of individual electronic components rather than integrated circuits. This design choice though more costly and time-consuming results in superior sound quality providing a more authentic and detailed audio reproduction.Semi-Passive RIAA EqualizationAfter processing the balanced signals independently they are combined and sent through a semi-passive RIAA equalization stage. Maintaining a fully symmetrical gain stage optimizes the signal-to-noise ratio and minimizes interference ensuring the equalization section receives an optimal signal for precise audio reproduction.Versatile Compatibility and
