Sorgente digitale Audio Alchemy in perfette condizioni estetiche e di funzionamento con imballi originali. Composta da:

Meccanica di lettura CD e HDCD (DDS Pro):
Pioneer Stable Platter drive based two blocks transport
Pass digital data through Cross Interleave Reed-Solomon Code (CIRC) error reduction processor, correct the errors, and remove error correction instructions from data bitstream
Reconstruct two channel digital audio into single datastream and deliver it to digital output jack 

Dispositivo anti-jitter (DTI 2.0):
Reclock the incoming datastream so the bits are spaced properly in time, reducing jitter 
Perform Digital Signal Processing (DSP), enhancing resolution to whatever maximum level the audio can maintain (e.g., 19 bit word length)
Optimize the word length so that it matches the D/A capability, e.g., dithering it up to 20 bits in the case of the DDE v3.0
Deliver the 20 bit audio digital datastream to digital output jack 

Convertitore D/A (DDE v3.0):
Digital filter the incoming datastream, including de-emphasis
Oversample
Redither the data line, this time to optimize it for the specific DAC chips used (Analog Devices 1862)
Digital-to-analog conversion
Analog filter (low pass) to remove everything above 20 kHz
Deliver two channels of analog audio to analog output jacks 

Prodotto di altissima qualità con prestazioni molto superiori ai concorrenti nella sua fascia di prezzo. 
La guida all'usato di FdS riporta un valore di 1000€ per la sola DDS Pro
