Unison Research – Unico CDUno – Hybrid DAC w/ CD Player

The Unico CDUno is a high-specification DAC with an integrated CD mechanism that is flexible and customizable. The CDUno combines Unison Research’s high-end sound quality with the broad playback possibilities offered by today’s digital audio solutions. The CDUno will allow you to play back all the music formats and sampling rates currently available on the market.

The UnicoCDUno boasts a wide variety of inputs and outputs. On the back panel there are inputs for USB and Toslink ™ cables, and built inside the housing is a Bluetooth™ receiver that allows for wireless streaming from compatible devices.

The audio stage uses one 12AU7//ECC82 double triode, operating in pure class A, followed by a solid-state discrete buffer still operating in class A for a low impedance output and ideal audio behavior.

Aesthetically the CDUno, like the CDDue, differs from existing Unico products with its new three-fold faceplate, white LEDs, and white display. This same aesthetic will pass over to the new Unico 90 and Unico 150 amplifiers, which are designed to be perfect matches for the CDUno and CDDue.

The UnicoCDUno is a simple to use but a feature-rich player. The new 128 x 64 resolution graphic display uses white OLED technology for excellent visibility in all lighting conditions and from any angle. The “Display” function on the remote control allows you to turn off the display so you can enjoy listening without any illumination. The display shows the most important information in large fonts and additional information in smaller fonts

DAC board and features

The CDUno has been designed to separate the digital section from the analog one. The DAC section contains 8 stabilized power supply rails to ensure a clean and distinct delivery to each device on the board. Additional stabilizers are employed to ensure optimal sensitivity from the power supply; the first stabilizer acts as a filter, and the second removes any residual noise. All this has been done to ensure the DAC can operate in the best conditions possible.

It is possible to select from three different types of digital filters: F1 – filter high slope and linear phase, F2 – filter high slope and minimum phase, and F3 – filter low slope and linear phase. The three filters have characteristics that favor certain types of sound (temporal coherence, phase coherence, or impulse response) and this allows the user to select the digital filter that best suits the installation, registration, and tastes.

Valves Output stage

The tube stage uses two stabilizers, one for the anodic supply and one for the filaments. The path of the masses of signal and power have been designed in a particular way so they are combined in a “stellar-like” connection in the center of the board. From this point, you see the mass connection to the DAC board as a way to reduce noise and disturbances.

The CDUno has been developed through both extensive listening sessions and a meticulous R&D process. The result is an innovative product that accommodates the world of digital audio and delivers it to your system with a rich valve sound.

The audio stage is designed around a single 12AU7//ECC82 double triode operating in pure class A, defining the sonic performance of the unit, followed by a solid-state discrete buffer still operating in class A for a low impedance output and ideal audio behavior. The totem pole circuit is also used in the One and 150 in the Only 90 of the same line of CDdue.
