Luxman E-07 Phono Preamplifier

A phono stage has the delicate job of amplifying microvolt signals from a turntable pick-up without adding unwanted noise or altering tonal balance. The E-07 from Luxman joins the upper tier of solid-state phono preamplifiers, built specifically to extract every musical detail stored within vinyl grooves. Featuring a slimline aluminum chassis with a blasted white front panel, it integrates seamlessly alongside existing audio components while offering comprehensive control over signal processing.

Tailored Cartridge Matching:

Vinyl cartridges require precise impedance and capacitance settings to perform at their musical potential. The front panel features a six-position rotary selector for moving coil cartridges, allowing effortless adjustment across various impedance groups. On the rear panel, dedicated switches cater to moving magnet setups with multiple load and capacitance options. For moving coil cartridges, custom step-up transformers use high-responsiveness super permalloy cores across independent channels, while balanced XLR inputs help preserve channel separation and reduce electrical noise across long cable runs. This flexibility makes it an ideal central hub among high-performance phono preamps for multi-tonearm setups.

Clean Power and Signal Isolation:

To keep background hum and distortion to an absolute minimum, internal circuitry relies on four parallel low-noise FETs in the primary amplification stage. Power is handled by three separate transformers that isolate the left channel, right channel, and control circuits from one another, preventing load fluctuations from bleeding into the audio signal. Grounding is thoroughly managed through solid brass gold-plated terminals for each individual input, paired with a heavy-duty, dual-layer copper chassis base that lowers the centre of gravity and absorbs unwanted mechanical vibration.

Practical Control for Everyday Playback:

Front-panel controls give immediate access to helpful acoustic corrections without complicating the signal path. An articulator function demagnetises the cartridge and step-up transformer during record playback using the natural signal current. A switchable low-cut filter prevents low-frequency rumble from warped records from over-working loudspeaker bass drivers, while dedicated mono and phase-inversion controls ensure accurate playback across older pressings and varied system configurations.

• Independent Power Transformers: Eliminates cross-talk and voltage fluctuation between channels for a stable audio soundstage.
• Super Permalloy MC Transformers: Preserves minute detail and dynamic range from low-output moving coil cartridges.
• Front-Panel MC Load Selector: Allows quick impedance tuning to match the exact requirements of your specific cartridge.
• Balanced XLR Inputs: Suppresses electrical noise and improves stereo separation over standard single-ended connections.
• Dedicated Grounding Terminals: Minimises background hum by providing individual grounding reference points for each connected arm.
• Integrated Articulator Function: Cleanses magnetic buildup in the cartridge motor during playback to maintain high-frequency clarity.
• Dual-Layer Copper Base Plate: Provides structural rigidity and dampens vibration to protect delicate audio signals.
