Why it Sounds Amazing

DAC Chip

Know the secret to your pristine audio.

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.

SMSL SU 1 - My 3 week experience

SU-1 is my first DAC only product, i have tested various dac-amps but none of them are purely DAC. SU-1 in my opinion is well built, sounds good when paired with a good amp, depending on your preference.

For the price and the features that come alongside with SU-1, I think it is a no-brainer and easy recommendation. If SMSL is able to release another model without the MQA rendering, I believe the cost can be brought down a little, with all that being said, i’d still recommend this dac without any doubt!
Listening Impression using Home Theatre 5.1 system set up:

• Bass is presented with good texture, nice and decent sub bass rumble
• Punchy bass with good slams.
• Soundstage is widely spreaded.
• Sounds a little bit more musical overall to my ears when paired with SU-1
• Bass has good controlled and focus to the point - sounds a little fuller.
• Mids are being brought forward a little bit so Zero.
• Treble remains smooth while still being a little energetic.

If you’re interested in getting this unit, head over to Headphonezone’s store and get one now:

Wonderful little gizmo this is !!

I didn't expect too much from it given the rather low-end price but it punches way, way above its weight. I was pleasantly surprised by the details it brought out and the clear separation of instruments. Some reviewers elsewhere suggested that the sound was too bright and mids were too exaggerated. I didn't find that to be the case at all. It sounded quite neutral to my ears. I couldn't be happier with this purchase !!

Hey there,

This makes us really happy and we really appreciate the genuine feedback! Your review will definitely help fellow audiophiles to make an informed decision.

excellant value for money

I am still in the process of evaluating as I received the unit very recently . The performance is better than expected. I felt that it has an edge over the ifi zen air that i was using earlier in terms of musicality, sharper vocals and highs and cleaner bass. Would prefer some indication of the sampling rates , DSD, using LEDs as in the IFI unit. Yet under evaluation.

Hey Customer, thank you so much for the amazing feedback! It means a lot to us. We are so happy to hear that you are loving our products and services.
