The s.m.s.l RAW-HA1 delivers clean, neutral speaker sound with lively dynamics, crisp detail and impressively holographic imaging. Passion for Sound highlights its wide, deep staging and strong external-DAC potential, while its USB-C, HDMI ARC, Bluetooth and analogue inputs make this a remarkably complete compact hub for desktop, TV and living-room systems.
What Reviewers Are Saying
Pros
Clean, neutral and resolving speaker presentation, with wide/deep staging and notably holographic imaging for the price.
Strong speaker-amplifier headroom and dynamic punch for moderate listening levels.
Extensive connectivity includes USB-C, optical, coaxial, RCA analogue input, Bluetooth, HDMI ARC and subwoofer output.
Exceptional all-in-one value as a feature-rich DAC and speaker amplifier around $250.
&
Cons
Headphone performance is contested: one review found both outputs underpowered, thick and muddy, making it a risky headphone-first choice.
HDMI ARC may take two to three seconds to output sound after the TV is turned on.
Treble can become bright at higher volumes, particularly above roughly 85 dB, depending on speaker matching.
SOUND QUALITY PERFORMANCE 75/100
The RAW-HA1 earns strong praise as a compact speaker amplifier, with reviewers describing a clean, neutral and spacious presentation. Its headphone section is the major exception: Passion for Sound found it markedly underpowered, thick and muddy, so the positive speaker performance does not translate reliably to headphone listening.
Transparency Resolution
78/100
As a speaker amplifier, the RAW-HA1 is described as clean, precise and transparent, without the veil, muddiness or lack of resolution heard from some similarly priced alternatives. However, Passion for Sound found the headphone outputs muddy and lacking the same clarity, which substantially limits confidence in its headphone resolution.
Tonal Balance Musicality
77/100
Reviewers describe the speaker presentation as neutral, nicely centred between thick and lean, with slightly rich overall tonality and convincing midrange. The headphone output was specifically described as thick and muddy, indicating a less successful tonal result through headphones.
Dynamics
73/100
With speakers, reviewers heard good dynamic punch, solid headroom and unstressed moderate-level playback from the amplifier section. The headphone output was called incredibly underpowered, leaving little evidence that it can provide comparable authority or headroom with demanding headphones.
Noise Floor
80/100
One reviewer reported no audible hiss in a speaker setup, suggesting a generally quiet amplifier section. The reviews do not meaningfully assess background silence, hiss or gain behavior with sensitive headphones and IEMs.
Headphone Compatibility
68/100
Tharbamar reported powerful headphone drive with good grip and control and felt it could pair with many headphone types. In direct conflict, Passion for Sound called the headphone outputs pitiful, underpowered, thick and muddy; this leaves the RAW-HA1 a risky choice for headphone-first use, especially with demanding models.
Assessments of Build Quality, Usability, and Overall Propositions.
Build Quality
84/100
The binding posts are specifically praised as good quality, and the menu system is described as easy to use with clear graphical presentation. Reviewers provide little further evidence on chassis construction, controls, connectors or long-term durability.
Features Usability
91/100
This is a notably versatile all-in-one unit, with USB-C, optical, coaxial, analogue RCA, HDMI ARC, Bluetooth with LDAC and aptX HD, subwoofer output, digital filters, EQ functions and MQA support mentioned across the reviews. The input range and interface are considered good, although HDMI ARC can take two to three seconds to produce sound after the TV is switched on.
Value for Money
93/100
At roughly $250, Tharbamar calls it a highly capable, tremendous-value all-in-one component, while Passion for Sound considers it a favourite DAC-and-speaker-amplifier combination around this price. Those endorsements concern its speaker-focused performance and rich feature set; the weak headphone output makes the value proposition less persuasive for headphone-led systems.
