D I G I C O D E    2.24           real full balanced Digital to analog convertor


 

 

 

 

 


24 bit  96  khz  multibit, multivel digital analog convertor

full balanced with tube analog output.

Lector proudly introduces the all new Digicode 2.24 digital to analog convertor with tube analog output featuring full balanced circuity from digital input (Aes-Ebu XLR) to analog output (XLR audio analog). Audio analog output is based on four double triode on class A configuration circuit.

Digital to Analog convertor adopt the multibit DAC PCM-1704 from BB (no the economical sigma delta dac) four dac and four tubes: they are electrical connected without any coupling capacitors (DC connect) the dac works as differential mode so the balanced signal is generated from the digital source.

We have set-up by trimmer the critical single MSB on DAC for obtain highest real resolution . With special digital filter is possible to choice the right number of coefficients and slope for better listening choice as sound preference.

The analog output section uses  selected 4 double triodes in pure class A ( 4 tubes ECC-81 or 12AT7) . Tubes are selected for lowest noise and tuning trimmered for precision voltage output.

The conscruction of Digicode is modular: with three removable cards is easily replaceable in case of future upgrading for new technologies the individual form. A separate power supplu unit reduce the noise floor and magnetic influence to the circuit.

A digital circuit with recovey double PLL oscillator supply stable and precision LOCK-ON with perfect matching with our Digidrive CD-Transport

Sonic performance delivers pure enjoyment: thanks to the low noise printed circuit board design as real star ground. What you listen is just the sound of your favourite tubes operating with exceptional linearity in a class A gain stage.

We can spend many words trying to describe its purity, its great dynamics, its airy soundstage, its accurate imaging, its ability to resolve the subtle details and many other outstanding qualities of this exceptional D to A convertor. But we prefer to simply invite you to listen to it and to trust more what your hear.
