Roksan Attessa Streaming Amplifier – Black

Here we have a nice example of the well regarded Attessa streaming integrated amplifier from Roksan. It is in very good condition, noting a couple of tiny blemishes – please see photographs. It comes well packaged in original box (non original internals), with remote control, reprinted manual, mains cable, and as always our standard three month warranty.
Roksan Say….
Attessa Series 1G reimagines Roksan for today’s connected user, nearly 40 years on from its founding, in London, UK. Attessa Series 1G comprises three highly contemporary models that extract the most from your music, whatever the source. The power of BluOS is built-in to the Streaming Amplifier, and the CD Transport can be connected to either the Streaming Amplifier or Integrated Amplifier to create an intuitive paired system. All of which can be quickly and easily set up and controlled using MaestroUnite, Monitor Audio Group’s easy-to-use app for connected devices, turning Attessa Series 1G into a truly versatile, connected high-fidelity system.
Attessa Series 1G uses Roksan’s new authoritative and intelligent class AB amplifier architecture, Euphoria.
A power amplifier has two main sections that interact with each other – yet have quite different characteristics. One increases the voltage of the signal up to the required level to drive the speaker, and the other increases the current to drive a speaker’s low impedance.
Both sections have been carefully scrutinised by Roksan’s engineers, and each area has been performance engineered and improved to ensure that the harmonic and intermodulation distortion is flat across frequency and load. The resulting sound is purer, more detailed and cleaner.
The Attessa Streaming Amplifier utilises BluOS premium multi-room audio streaming. The world’s premier wireless ecosystem, it provides users with access to limitless music via the world’s most popular streaming services, and the ability to wirelessly stream music at lightning-fast speeds with no lag and zero loss in sound quality.
Users can stream up to 64 zones of high-resolution audio, in quality up to 24-bit, 192kHz. Using BluOS also means effortless browsing, and access to locally stored music collections as well as streaming services.
With the Attessa Streaming Amplifier, users can enjoy a fully immersive whole-home enhanced listening experience in true high-fidelity.
Attessa Series 1G uses a powerful analogue pre-amplifier section. Its aim is to ensure that the signal is kept as clean as possible. A carefully configured and a fully balanced design, it delivers exceptional levels of noise rejection. It also features a novel ground switching input design that keeps cross-talk between connected devices to an extremely low-level, particularly important for the phono-stage performance.
Phono Stage
The Attessa phono stage allows for extremely accurate playback of vinyl. With a dedicated input for MM cartridges gain adjustable for low, mid and high output types.
Both the Attessa Integrated Amplifier and Streaming Amplifier benefit from an elegantly clutter-free appearance. Buttons and control dials have been purposefully kept to a minimum, with the sole focus of user-interaction being the central control dial that provides users with access to all features. These features are indicated with clearly defined graphical icons on the sleek OLED displays either side of the central control dial.
Designed to provide straightforward operation for non-technical users, this approach ensures that source select, volume control and even pre-sets are immediately accessible. Getting great high-fidelity sound quickly and easily is at the bedrock of Attessa Series 1G’s DNA, and this it does with gusto.
Attessa Series 1G utilises Monitor Audio Group’s in-house designed MaestroUnite app. This helps users to quickly set up their device, enabling connection to a local Wi-Fi network ready for Internet of Things (IoT) functionality.
Furthermore, the MaestroUnite app gives users control of features such as input configuration, headphone sensitivity, analogue input gain, balance and low power standby. It also provides access to Roksan’s innovative DSP Engine’s enhanced features, which help users tailor their listening for a specific environment.
The Attessa Streaming Amplifier unleashes the power of BluOS, premium multi-room high-resolution wireless streaming, coupled with powerful amplification. Plus, the Attessa Streaming Amplifier provides users with one-touch access to great sound from all their devices, from TVs to turntables, games consoles to CD transports.
Furthermore, thanks to the MaestroUnite app users can enjoy all this high-fidelity capability via the kind of intuitive, smartphone-based control that we’ve come to demand in every area of our lives. The technology is highly advanced but using it couldn’t be simpler. So now, users can enjoy high-fidelity audio in every room of their home – all at the touch of a button.
