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.
