A simple, high-fidelity streaming amp

Roksan Attessa Integrated Amplifier with Bluetooth®

The Roksan Attessa streaming amp handles digital and analog sources — including vinyl — with nimble, muscular Class AB power and onboard BluOS.

Introduce yourself to powerful British hi-fi sound with Roksan's Attessa streaming amp. It's got plenty of digital and analog connections, including a phono input, a built-in high-performance DAC, plus BluOS and Bluetooth with aptX® for wireless streaming.

And along with a really pleasant user-interface, it sports a refined industrial design and solid construction. 

Robust Class AB amplification and construction

The Attessa is 4-ohm stable and can handle a wide range of speakers. Its powerful Class AB amplification can deliver 80 watts per channel into 8 ohms and 130 watts into 4 ohms.  

The burly plated-steel construction and an anodized aluminum faceplate add to the heft of this amp. It has a central volume/source knob that you turn for volume and press to toggle through sources. Three front-panel buttons let you control music playback. The display is easy to grasp at a glance, with source selection displayed to its left and volume level on the right.

Flexible connections and high-res DAC

The Attessa's four digital and three analog inputs let you connect all sorts of stuff. You can add a turntable, CD player (the Attessa Turntable and CD Transport would be perfect matches), tuner, or what have you. To open up the world of digital music streaming, you'll connect to your home network using Ethernet or the included Wi-Fi dongle. And all of your digital sources will receive proper treatment from the built-in high-resolution DAC, which Roksan designed in-house.

The amplifier's AV bypass feature lets you connect the appropriate output from your home theater receiver to the Attessa to power your front left and right mains. And if you want to do some more discreet listening, plug into the front-panel 3.5mm headphone jack.

BluOS high-res streaming and multi-room expansion

The Attessa Streaming Amplifier's built-in BluOS streaming platform gives you access to a wide variety of streaming sources using a free app on your mobile device. Play TIDAL, Qobuz, Spotify® and more — as well as music files on a network-attached computer, NAS drive, or USB thumb drive. And you can add, group, and control other BluOS speakers and components (sold separately), so you can have app-controlled music in different setups throughout your home.

App and remote control

You can use the included remote and the free MaestroUnite app for Apple® and Android™ devices to control the amp. Select sources, control playback, and change settings like the input sensitivity of your analog inputs, including gain settings for the moving magnet phono input, and more.

Roksan's British heritage

Roksan was founded in England in 1985, where the company continues to design and engineer its products. Their first product — the ground-breaking Xerxes turntable — established Roksan's expertise in vinyl playback, but since then the company has turned its attention to hi-fi digital audio and amplification, as well.
