Lector-Audio

When the perfect mechanical solution join original electronic design born a superior cd player class A product.

several original mechanical solution are adopted as proprietary (internal Lector factory made) read out laser mechanism and special made brass pillar suspension
separate power supply with indipendent section mains AC power switch ON/OFF (digital/analog) three power toroidal hi-flux transformers
exclusive CD disc clamp with two axis stabilization effect by special neodinium magnet
sophisticated selection off DAC type dual mono PCM-1704 BB 24 bit with indipendent board pcb for real jitter reduction
NO any type of feedback total or local circuity can control the analog stage, a original circuit design drive and control the gain of the first tube stage ( chatode direct drive coupling )
passive dithering circuit increase real bit resolution near to the barrier of 24 bit ( Lector invented this original circuit design)
custom made CD mechanism with three isolated plate stages and vibration system discharge control spindle
original proprietary servo digital board with new technology solution design ( we don't use the kit electronic board )

The circuity of power supply employ 14 regulation stages , only one capacitor on signal path as film & foil custom made, special material chassis by aerospace alluminium die-cast. The output tube triode circuity is in class A with only one passive first order filter so do not have indesiderate rotative signal phase.

The CD mechanism have two different solution of mechanical damping:

the first by special damping rubber in neoprene
the second by lattice-rubber as similar solution adopted in analog turntable.

A original magnetic clamp system give more stability to the rotation the CD disc so to have the double stabilization on two axis: orizzontal and vertical.
