Roksan Audio Ltd

The Roksan Attesa Streaming Amplifier combines an AB-class integrated amplifier and a modern player-streamer equipped with a highly efficient network module. The module is based on the progressive BluOS operating system, which allows integrating this model into a wireless multiroom ecosystem with the ability to play up to sixty-four separate music zones and access to numerous web radio stations and online services, including Spotify Connect, TIDAL Connect, Deezer, Qobuz, HDtracks, HighResAudio, etc. BluOS makes it possible to transmit Hi-Res audio over the air in a resolution of up to 24 bit/192 kHz.

The Roksan Attesa CD Transport is equipped with a drive optimized for CD-Audio playback, as well as CD-R compatible. On the front panel of the device there is a miniature display showing the main operating modes of the Roksan Attesa CD Transport, as well as control buttons for the most frequently used functions. Access to all the settings and functions of this model is possible in the remote control. The placement of the CD-ROM drive in the center of the transport chassis not only provided this model with a more accurate and attractive appearance, but also allowed it to align its center of gravity, as well as minimize unwanted resonances.

The integrated amplifiers of the new Caspian 4G series use Roksan's proprietary Euphoria Class AB amplification technology, which, according to the developer, "combines power and elegance." This technology uses separate power sources for current and voltage amplifiers to achieve a clearer sound. The analog preamp section in the new series has also undergone a major upgrade.

An amplifier based on the Attesa line. Built according to the innovative Euphoria architecture with a "smart" class AB. It is equipped with a hybrid volume control and a built-in Rapture DAC, a MM phono corrector with an accuracy of 0.5 dB recovery of the RIAA curve. The signal processor of the device is controlled via the Maestro Unite mobile application. The display is monochrome OLED.

The amplifier operates in the AB-class and is equipped with a linear power supply unit with a massive 400 VA toroidal transformer, which can output 80 watts per channel at 8 ohms and 130 watts at a four-ohm load. In addition to the two linear analog inputs, the amplifier has two optical and two coaxial digital inputs, the latter allowing decoding of the PCM stream from MQA. Digital-to-analog conversion up to 24/192 is implemented on a Burr Brown chip. The aptX Bluetooth wireless connection ensures stable transmission of music content from mobile devices at a distance of up to 15 meters.
