EISA 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.

Roksan Attessa Streaming Amplifier Review

"Roksan's all-new, in-house, 80Wpc design embodies where today's marketplace lives. Attessa is its first offering with integrated DAC plus network streaming capability and a fine mm phono stage too. Sonic performance registered high scores across all genres of music. It was grain free, non-edgy and wasn't apt to shade or spotlight particular frequency bands. It maintained a ripe and natural midrange, a weighted tonality, a firm and controlled bass, and a smooth if slightly drier top-end. Throughout, there was a spotless untrammeled clarity to every note. Attessa was especially impressive imparting dynamic energy in both the macro and micro senses. Looks, ergonomics, and performance. In NG's book, a real sleeper." The Absolute Sound Editors' Choice Awards 2023

"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 the one to beat in a hotly competitive division. Highly recommended." The Absolute Sound

Our Take

Another day, another streaming amplifier. It seems only a few years ago (actually more like 15) that Sonos brought out the first ever streaming amplifier, the Connect Amp. As innovative as the Connect Amp was, with Sonos streaming capabilities built-in, it was certainly no high end product. Then, genuine audio companies like Naim started to bring out streaming amplifiers with their Uniti range and now it seems like the floodgates have opened and every Hi-Fi company and their dog can't wait to release a version of their amplifier that has a music streamer built in. The amplifier itself is normally a given as it's often using an existing, well specified integrated amplifier which is certainly the case here with the Roksan Attessa. However the streaming section & associated smartphone/tablet App sometimes leaves a little something to be desired. Fortunately Roksan had the good sense to licence the BluOS streaming technology from Lenbrook which you can find inside Bluesound & NAD products. BluOS is one of the smoothest streaming systems you will ever experience and it's the first time we have seen such a partnership from outside the Lenbrook group of companies. We hope it happens a lot more as this product started selling before we even had it added to our web site, which is always a good sign.
