Roksan Attessa Streaming Amplifier
Roksan’s Attessa Streaming Amplifier brings rhythmic agility, tonal warmth and muscular Class AB drive to a remarkably complete one-box system. StereoNET admired its pace and musical cohesion, while The Absolute Sound highlighted clean, controlled dynamics. BluOS streaming, an MM phono stage and generous connectivity make its natural midrange and confident power especially compelling for modern vinyl-and-streaming systems.

Rhythmically agile, warm and musically cohesive presentation that makes varied music immediately engaging.
Strong Class AB power delivery remains clean and composed through demanding dynamic swings and high listening levels.

Cons
Not the last word in large-scale dynamics, fine textural nuance or sonic precision compared with top rivals.
No Chromecast support or HDMI eARC input, which may limit convenience in some streaming and TV systems.

What Reviewers Are Saying
SOUND QUALITY PERFORMANCE 90/100
Reviewers consistently found the Attessa engaging, clean and musically assured, with a warm-to-neutral balance, strong timing and substantial control. Its streaming and DAC performance attract particular praise, while the main reservations concern ultimate textural subtlety, large-scale contrast and three-dimensional depth versus stronger rivals.
Transparency Resolution
91/100
The Absolute Sound heard spotless, grain-free clarity, very low apparent noise and a DAC that gave up little to a far more expensive Lumin source. The Ear likewise found a rich yet detailed sound and a silent phono input, although The Audiophile Man found the internal DAC less insightful than a good external alternative.
Tonal Balance Musicality
91/100
Its sound is widely described as warm, natural, smooth and highly listenable, with ripe midrange tones and well-controlled bass. What Hi-Fi? and StereoNET especially praise its likeable, agile musical character, though several reviewers note a slightly dry top end and less extreme bass or treble extension than some alternatives.
Dynamics
91/100
Multiple reviewers praise the Attessa's pace, rhythmic drive and ability to remain composed at high levels. The Absolute Sound found macro- and micro-dynamic swings impressively secure, while The Ear reported powerful, controlled playback without hardening; What Hi-Fi? and Hi-Fi News wanted greater large-scale contrast and snap.
Soundstage Imaging
88/100
Reviews commend strong instrument separation, stable placement and a spacious, organised presentation. The Ear heard convincing height, width and depth, but The Absolute Sound found images less dimensional and hall depth somewhat shortened compared with higher-end reference equipment.
Assessments of Build Quality, Usability, and Overall Propositions.
Build Quality
89/100
The steel-and-aluminium chassis, machined anodised front panel and substantial 10kg-plus weight receive consistent praise for solidity and finish. What Hi-Fi? calls it sleek and well made, while The Absolute Sound reports glitch-free operation; reviewers say less about long-term durability.
Features Connectivity
95/100
This is a genuinely comprehensive one-box system: BluOS streaming, Ethernet and Wi-Fi, a capable DAC, aptX Bluetooth, MM phono stage, headphone socket, USB playback, four digital inputs, analogue inputs and pre-out/subwoofer connection. BluOS is repeatedly praised for stability, service support and usability, although the lack of Chromecast and LDAC are notable omissions for some users.
Value for Money
92/100
At roughly $3,199-$3,399, The Absolute Sound calls it a leading contender in a highly competitive field and regards the purchase as savvy against a Lumin costing more than three times as much. The Ear also highlights the amount of thoughtfully integrated technology, though The Audiophile Man felt the asking price warranted more in some respects.
