All-solid-state, high-quality NF-type phono equalizer amplifier
Since phono equalizer amplifiers must handle minute audio signal voltages generated by analog audio products, the E-07 excels by applying LUXMAN’s extensive experience and expertise in amplifier circuit technology. This unit features a high S/N ratio, MM/MC compatible RIAA curve and high-quality NF-type transistors, utilizing a low-noise circuit design, achieved by paralleling four individual FETs in the primary stage. This phono amplifier incorporates carefully selected components prioritized for supreme audio quality; including high-end, original, custom developed components, all of which have gone through extensive listening tests, resulting in a rich, dynamic sound, worthy of LUXMAN’s approval. The chassis, a crucial element influencing sound quality and tonal characteristics, employs a loopless chassis structure that isolates the power supply from the amplifier sections while minimizing ground impedance generated by chassis currents. Additionally, the OFC cable, used for all internal wiring, has precise, spiral-wrapped shielding and pure, unplated copper cores to ensure natural signal transmission and clarity. The design features gold-plated, reversed AC inlet that supports heavy IEC cable weight across the terminals, further enhancing the essential elements required for optimal analog playback.
Precise load adjustment for optimal cartridge performance
The E-07 features a six-position rotary load impedance selector for MC cartridges (4.7/10/40/100/300/1kΩ) on the front panel. The rear panel has load impedance selector switches for MM cartridges (34/47/56/100kΩ) as well as load capacitance selector switches (0/100/220/320pF). This allows for more precise adjustments to fully maximize the sound quality across a wide range of phono cartridge types.
Large capacity power transformer with independent filtering
The E-07 features a total of three robust power transformers, configured independently for left and right audio processing circuitry, as well as a separate transformer for the indicators and relay drive circuits. This design creates an ideal power environment where load fluctuations in each circuit block do not interfere with one another. Additionally, it is equipped with excellent, independent power supply regulation that yields an extremely stable current supply, thanks to our power amplifier-grade, large value block capacitors (10,000μF x 5).
Large independent brass grounding terminals for each input
For the E-07, we have introduced large grounding terminals machined from solid brass with a gold-plated finish. Each input terminal (Unbalanced 1, Unbalanced 2, and Balanced 1) is equipped with a dedicated phono ground terminal connected to that circuit's reference point, along with a traditional frame ground terminal connected to the main chassis, for a total of four terminals. This ensures the secure grounding wire connections and minimizes the occurrence of hum, noise and other interference.
