UNISON RESEARCH UNICO CD UNO

Description

Unico CDUno It is a top-level DAC with an integrated CD reading system, it is flexible and customizable in use. The CDUno combines the quality of Unison Research sound with the possibilities offered by digital systems, through an external source or a computer it allows the reproduction of PCM and DSD digital audio in all formats and sampling frequencies currently available.

Just a look at the back of the device is enough to realize the various digital inputs available: USB and Toslink. What you can't see is the Bluetooth™ receiver which allows the playback of music from mobile devices without the need for cables.

The output stage, as in the Unison Research tradition is tube-based, has two balanced and two unbalanced outputs. It uses an ECC82 double triode operating in pure class A followed by a discrete component buffer also in class A which allows a low output impedance

Aesthetically, CDUno, like CDDue, differs from past productions due to a new front and the white LEDs also used in the Unico 150 and the Unico 90.
