Descrizione
Il DAC DirectStream di Classe A + classificato stereofilo converte qualsiasi formato di ingresso digitale, come PCM o DSD in un flusso DSD puro e trasmette un analogico quasi perfetto direttamente al tuo amplificatore di potenza o preamplificatore. Qualunque sia il formato, qualunque sia la frequenza di campionamento, DirectStream è una pura soluzione basata su DSD che soddisfa la promessa di uno standard di prestazioni analogiche ad alta risoluzione promesso dai creatori dei CD oltre 30 anni fa. Ascolta cosa è mancato nella tua musica in tutti questi anni. Se conosci il suono della musica e degli strumenti e vuoi ascoltare cosa manca sui tuoi dischi, allora questo DAC è giusto per te.

This is a DAC that suits a relaxed style of listening and because great tone is such a huge part of what makes music enjoyable to many, it’s appealing to a vast plethora of music…
What is Clear with these characteristics is that the DirectStream is going to hugely appeal to John or Juliette Vinyl, who do things the old way but want a foray into streaming and digital audio. Or anyone who wants a relaxed sound in digital for that matter. Now is a good time with CD on shaky ground with streaming services soldiering on. It’s consequently the dream DAC and streamer for such people – non digital sounding digital!!!
Forget the old reckonings of the past about insidious edgy treble in DACs as to why your music must spin round and round. That thinking is now as far away as Earth is to Mars. DACs like the DirectStream change all this!
