Why it Sounds Amazing

DAC Chip

Know the secret to your pristine audio.


This headphone or gear reveals the secret sauce behind superior audio quality, highlighting the presence of a high-performance DAC chip for pristine sound reproduction.


If you see products marked as “⚙️ DAC Chip”, expect to experience your music with unparalleled clarity, detail, and fidelity, ensuring that every note and nuance is faithfully reproduced for your listening pleasure.

Sampling Rate And Bit Depth

Ever wonder how those ones and zeros on your computer magically transform into the rich melodies that fill your room?


The secret lies in a tiny device called a Digital-to-Analog Converter (DAC). Think of it as a translator, taking the digital code of your music and meticulously sculpting it back into a smooth, analog wave that your speakers can understand. But just like a sculptor needs the right tools, achieving audio nirvana with a DAC depends on two key factors: sampling rate and bit depth.


Sampling Rate:

Imagine your favourite song as a complex rollercoaster track. The sampling rate refers to how often the DAC takes measurements of this digital track, measured in kHz (kilohertz) or thousands of times per second. A higher sampling rate, like 96 kHz, is like taking a ton of pictures of the track, capturing every twist and turn with incredible detail. Lower rates, like the standard 44.1 kHz used in CDs, are like taking snapshots at a theme park – fun, but you might miss some of the subtler details that make the ride truly exhilarating.


Bit Depth:

Now, think about the sculptor's tools. Bit depth refers to the precision of each measurement the DAC takes. Imagine the number of colours available to the sculptor. With higher bit depth (e.g., 24 bits compared to 16 bits), each measurement can capture a wider range of values. This allows the DAC to recreate subtler variations in the sound wave, resulting in richer and more nuanced audio. It's like having a broader colour palette for building a more detailed and lifelike sculpture of the sound.

Excellent DAC with a great price to performance ratio

Bought this DAC after going through several reviews on numerous sites like ASR etc. Amazing DAC for the price. It stays true to the source and is very neutral without coloring the sound signature. Though I was not able to make it work directly from an Android phone via direct USB C connection, leveraged the Co-Axial and Optical connectivity options. Have been using it now for more than 2 weeks and have my TV Unit and Speakers hooked onto it with Fosi Audio ZA3 Amp in my study room. Sounds fantastic. For the price range of 7-8K, this is definitely worth a steal. Great product by SMSL.

Thank you for taking the time to leave a review for the S.M.S.L SU-1.

SMSL rocks (Jay S)

It’s a fantastic DAC for 7K and this can easily compete with 50 K DACs easily.
Superb presentation of highs, mids and lows. It’s like hearing in a theatre. Great find and kudos to SMSL.
Had they given one more input mode it would have been great but no complaints. The build is too good and it’s compact and cute. Go for it guys and you won’t regret.
Kudos to Headphone Zone for on time delivery.

Hi Jay, thank you so much for sharing your positive experience with the product! Happy listening! :)
