Luxman E-250 Phono Amplifier
Experience the ultimate in vinyl playback with this complete phono equalizer designed for rich analog reproduction. The E-250 inherits the best design elements from its legendary predecessor, the E-200, while adding advanced cartridge optimization features for unparalleled musical expression.
✨ Key Features
🔧 Optimized Cartridge Load Adjustment
The rear panel is equipped with a comprehensive load impedance selector offering four precise settings (34kΩ, 47kΩ, 56kΩ, 100kΩ) and a load capacity selector with four options (0pF, 100pF, 220pF, 320pF). This dual adjustment system allows you to perfectly match your cartridge's electrical characteristics, whether you're using a high-output moving magnet (MM) or low-output moving coil (MC) cartridge.
The result is optimal impedance matching that extracts every nuance from your vinyl records, allowing the listener to fine-tune settings for each performance and release the full expression engraved in the grooves.
⚡ Specially Selected MC Transformer
At the heart of the E-250 lies a meticulously crafted step-up transformer with 2-stage gain selection featuring left and right independent super permalloy cores. This transformer design supports even the most challenging low-impedance MC cartridges, providing the necessary gain boost while maintaining signal purity.
Unlike electronic amplification, transformer coupling creates a rich, warm musicality that preserves the natural harmonics and spatial information of your records. The super permalloy core material ensures minimal distortion and maximum magnetic efficiency.
🔋 Large Capacity Power Supply Circuit
The newly developed power supply features a low-profile, large-capacity block capacitor paired with a discrete component regulator circuit. This combination provides exceptionally clean, stable power with minimal ripple and noise. The power supply also incorporates LUXMAN's proprietary round pattern board design, which optimizes current flow paths.
This advanced power supply architecture ensures that delicate phono signals are amplified in the cleanest possible electrical environment, preserving micro-dynamics and low-level detail that bring your records to life.
🎯 Articulation Function
This innovative feature addresses a common problem in analog playback: cartridge and transformer magnetization. Over time, magnetic components can become magnetized, causing sound quality deterioration. The articulation function uses the actual music signal current to systematically demagnetize both the cartridge and MC transformer.
By restoring the magnetic components to their original neutral state, this function helps maintain peak performance and can dramatically improve sound quality when magnetization has occurred, ensuring your system always performs at its maximum potential.
📊 NF Type Equalizer Circuit
The E-250 employs LUXMAN's advanced Negative Feedback (NF) type equalizer circuit built with many original and custom components. The circuit features parallel-connected first-stage FETs that significantly reduce noise while maintaining high gain. Additional features include a monaural switch for mono records and a low-cut filter to eliminate rumble and warp-induced low-frequency noise.
This sophisticated equalization approach achieves an exceptional signal-to-noise ratio while accurately implementing the RIAA curve, ensuring faithful reproduction of the original recording's frequency balance and dynamics.
🎛️ Dual Input Selection
The front panel features convenient 'one-touch' input selection allowing you to switch between two separate turntables or a single turntable with a dual-arm setup. Each input can be independently configured for different cartridge types (MM or MC), giving you the flexibility to optimize settings for different cartridges.
This feature is perfect for audiophiles who want to compare different cartridges, use specialized cartridges for different types of music, or simply have the convenience of two turntable setups ready to play at any time.
