Préamplificateur numérique Pro-ject Audio Prebox S2 (préamplificateur de ligne stéréo)

Pre Box S2 Digital marque une nouvelle ère pour nos composants de la série S. Pour la toute première fois, nous utilisons une configuration double mono avec les convertisseurs N/A de la plus haute classe d'ESS Sabre. Leur puce DAC phare garantit un son de la plus haute qualité dans un boîtier petit et abordable. Ce DAC est capable d'audio haute résolution jusqu'à 32bit/768kHz PCM et DSD512 ! Pre Box S2 Digital est également le tout premier de nos appareils à prendre en charge le déploiement matériel MQA. C'est également la première de notre filtre numérique transitoire Optimum propriétaire et de notre conception de circuit d'horloge propriétaire. L'audio numérique est l'art du temps, avec notre nouvelle conception d'horloge propriétaire, nous avons géré des taux de gigue inégalés de 100 femtosecondes, ce qui surpasse facilement de nombreux générateurs d'horloge audiophiles renommés et respectés ! Avec des condensateurs en polymère organique et des résistances miniMELF à couches minces, nous avons pu créer un petit appareil qui fera exploser des composants encore plus gros pour un prix beaucoup plus élevé. Avec un total de huit filtres numériques, le son peut être façonné précisément selon les souhaits des auditeurs. La Pre Box S2 Digital est entièrement télécommandable, elle peut aussi piloter le logiciel de lecture d'un ordinateur. Vous pouvez utiliser Play, Pause, Forward et Rewind directement avec votre Pre Box S2 Digital !

Livraison très rapide. Produit très qualitatif (liaison vers ampli via cable USB, Coax ou SpDif), plus sortie casque (6.3mm). Une alimentation externe accompagne le produit mais ne fonctionne correctement que sur la liaison Coax et SpDif (la liaison USB assure sa propre alimentation).Penser à acheter les cables liaison en conséquence (non fournis).PS. une étoile en moins pour la confusion alimentation externe - port USB.

Still testing the sound but so far it's very good. Using it between a Yamaha AX-497 amp and a Bulesound node 2i (coax digital) / an old Kenwood DP-SE9 CD deck (optical). Wanted to see if its dac adds anything to bluesound. It does. At first it sounded just 'plain' than compared with the bluesound plugged into the amp via RCA, but after some comparison the impression is that it's just more clear (less bass but more detail). With the cd deck over optical it's an amazing upgrade compared to the player's own rca outs. Can't really hear the difference with the individual filters on my setup. The fact that it only supports MQA over the USB port means you wouldn't want to buy it for mqa playback because of the hassle. USB doesnt work with Android. Practically this is an extremely good 2-channel dac preamp for your stereo or a great 'soundcard' for your desktop PC/laptop. In the latter use case, the headphone jack comes in handy. Haven't tested the headphone in the stereo build because I have a separate Head Box S2 from pro-ject.

While it was working it was sounding good and has good features. For the price though it is not worth as it gave up on me after 7 months and I have no idea what will happen : will they send me a new unit or not and what pain it will cause me. Very disappointed. I was hoping for good quality and reliable work, as advertised and now headache!Now suddenly the headphone amp stopped working. The RCA output is working but it has digital noise in audible levels.Update:After I installed the new driver it still continued to be the same. Then I unplugged the power and the usb cable to the computer end reconnected them again. Now the headphone amp is back to working condition, but the digital noise in the RCA output is still audible. Could be from some interference coming through the RCA cable as it is not a highest quality the one I use.

Great that the DAC may be powered by the USB connection or it's own power supply.Small but really delivers a fantastic sound.

You have to hear it to believe how good it is on HD650, Focal clear and Audeze LCD3The bad part he does not play will with othersI E he cause noise if add with another DAC even if separated and isolated but alone on hi end PC the DAC AMP is amazingAlso it is recognized by Roon
