Luxman E-06

An old-fashioned amplifier that wants to make a phono equalizer an independent component in order to thoroughly pursue quality.

The MC transformer of the manual winding design is carried in the MC transformer.
This transformer was made by a designer who designed and developed an output transformer for MB300, and the characteristics check and audition were repeated by the designer himself, and hundreds of prototypes were made. And PC-OCC is adopted for the wire material, and the wire diameter, core material, core stacking method, and shielding method are thoroughly examined.
The E-06 is thoroughly matched to all MC cartridges, such as installing two types of dedicated transformers with different boost ratios, one for each L / R, for a total of four. Furthermore, from the idea that balanced transmission is effective only for delicate MC lines, this MC transformer input can also receive balanced transmission.

The CR type equalizer circuit has a circuit configuration that uses a flat amplifier for both the 1st and 2nd stages.
Moreover, in E-06, the amplification element of a flat amplifier is fundamentally improved, and by carefully selecting and adopting a CR element, the sound unique to a CR type is realized.

The 32 point type ultimate attenuator is adopted as a volume circuit.
This attenuator was developed and designed for E-06, C-06, etc. by returning to the origin, and consists of a glass epoxy substrate, gold-plated finish, non-magnetic resistance wiring, die casting, shield case made of extruded material, etc. increase.
The E-06 uses L / R independently, and in order to obtain a more natural volume change, the curve characteristics as a trim control that can finely adjust the output balance of the cartridge in 0.5 dB steps near the maximum output are provided. I have it.
In addition to the variable output, it also has a direct output terminal.

The flat amplifier is adopted as an input amplifier and an output amplifier of an equalizer circuit.
Since these circuits handle signals with different phases before and after equalizing, if this part is used as a common power supply, unfavorable results will occur in terms of sound quality.
Therefore, in addition to the left and right transformers, the E-06 uses a constant voltage power supply suitable for each of the input amplifier and output amplifier to improve sound quality.

PC-OCC (single crystal high purity oxygen-free copper wire) is adopted as a wiring material.
In addition, a nitrogen gas-filled gold contact input switching relay that uses contacts in parallel, a bus bar that reduces power supply impedance, a first-stage block with a reinforced shield, a glass epoxy board with a monocilic layout with an L / R separation shield, and signals. Parts that prioritize sound quality are used, such as the adoption of a non-magnetic chassis that eliminates the effects of noise and vibration and a hard wooden cabinet.

A line phase sensor that can detect the polarity of the AC power supply is installed, and the sound quality is improved by unifying the polarity of the total system.
Since the polarity is strictly controlled on both the primary and secondary sides of the power transformer, the effect of unifying the polarity can be obtained in combination with the line phase sensor.
