"Indeed, the Roksan Attessa turned out to be a real sleeper. Looks, ergonomics, and performance-a lot of pieces must fall into place to successfully bring together digital and analog sections, sophisticated software, plus Wi-Fi and network capability. It's no small task, but with Attessa Roksan has fully met the challenge and then some."

"...the Attessa is likely to beat in a hotly competitive division. Highly recommended."

- Neil Gader, The Absolute Sound, February 2023

"Perhaps the most conventional of BluOS amps around, Roksan's Attessa SA partners its hi-res streaming talents with a range of physical connections, a clean, smart aesthetic and a Class AB power amp that keeps on giving. Yet the USP of this entry-level device is arguably its musical bent – there's a grown-up performance here that'll have you listening for hours."

- Mark Craven, Hi-Fi News, April 28, 2021

EISA Award-Winning Streaming Amplifier 2022-2023

"With a sleek design that’s both an homage to classic Roksan hardware and a refreshing take on a ‘just-add-speakers’ amp, you could be mistaken for thinking the Attessa Streaming Amplifier is all about form, not function. But this powerful Class AB amp is focused on fulfilling your musical needs, both via wired inputs – including an excellent MM phono stage – and the superb BluOS streaming platform. To these multiple digital and analogue inputs is added app-based control and multiroom functionality. Performance, too, is exemplary – the Attessa Streaming Amplifier has a grown-up sound that’ll have you listening for hours, driven by a power plant that just keeps on giving."

- Expert Imaging and Sound Association (EISA), 2022

"The Attessa takes a great on paper specification and uses it to deliver a comprehensive and satisfying performance. So long as a modicum of care is taken with your speaker choices, this is a capable and likeable amplifier that should win many friends."

- Ed Selley, AVForums, January 14, 2022
