Bonjour,

je vends un convertisseur APL HIFI DAC-S   , datant de 2009/2011 , seconde main
dans les premieres réalisations de alex peychev , acheté à une connaissance de Mr peychev
dac très intéressant  , son prix neuf était de 5000 euros

je l'aurais bien conservé mais entre temps j'ai trouvé un lecteur esoteric intégré que je recherchais d'occasion depuis un certain temps

j'en désire 1300 euros / très bon état / carton d'origine et télécommande ci dessous le descriptif technique

attention ce n'est pas un dac dsd-s qui est une réalisation postérieure d'APL

description technique :

APL Hifi DAC-S

Bulgarian base APL Hi-Fi a.k.a Alex Peychev worked extensively with Sony Broadcast and has 25 year experience in the digital field.

The DAC-S is an all-solid-state DAC with eight 32 bit AKM4399 per channel in mono mode, M2Tech 24/192 hiFace USB interface built in, discrete output stage, no negative feedback, no capacitors in signal path, and galvanic isolation of digital and analog stage.

Features:
•Professional grade digital input receiver
•Asynchronous Hiface USB interface by M2Tech built-in. 192kHz/24bit capability
•Asynchronous upsampling working steady at 195kHz/32bit
•Very low jitter Master Clock oscillator
•Second generation, top-line 32bit DACs by AKM of Japan; 8 per channel for much reduced noise floor, working in Mono mode for up to 10dB better channel separation
•No negative feedback, linear phase, transformer-coupled Analog output stage featuring Lundahl Amorphous Core audio transformers and high-current output buffers
•No capacitors on the signal path
•No Op Amps
•Galvanic isolation between Digital and Analog stages, eliminating digital noise ground interference in the Analog output stage
