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.


The SMSL D300 is an excellent budget DAC with a super rare and flagship-grade ROHM chip. You can forget about any harshness, edginess, or high-frequency glare while listening to music on the D300.

It enables high-resolution signal decoding with ultimate precision and quality.

STABLE PERFORMANCE WITH ULTRA-LOW JITTER CLOCK SYSTEM

The SMSL D300 has been embedded with an ultra-low jitter clock system that offers stable and artefact free audio. The D300 utilises a brand new CK-03 clock signal processing circuit. This circuit provides an ultra-low jitter for all the inputs including USB, Coaxial, Optical and Bluetooth. This effectively improves the output signal quality from the DAC bringing you close to true & pure sound output. Unlike many DACs, which reserve the best clocking for the USB input, the D300’s CK-03 clock processing circuit ensures ultra-low jitter across all inputs.

Very natural & accurate sounding DAC

This is one of the rare DACs with natural / organic sound, accurate sounding with all the details / nuances without any harshness or sibilance. I would consider this as the best DAC under 50K at the moment in the market.

Hey there, nothing makes us happier than knowing you loved your purchase, hope you had a comfortable shopping experience and thank you for the great review and ratings!

You cannot turn off the music!

Wow! What a DAC! I went with this DAC over SMSL SU-9U, SU-9U Pro, Topping E70 Velvet, E70. Of course, there was no way to listen to it before buying, so most of the reading was online, looking up YouTube, and help from Ian Pereira of HFZ.

I was looking for a DAC with the right amount of detail + warmth at the same time. Pairing it with a Rega Brio and Wharfedale Lintons, and boy I am truly impressed.

I listen to all kinds of songs, from Blues, Country, Pop, Jazz, 70s and 80s rock, some of the new stuff too! Close your eyes, and you can feel the artist/band in your room! It is that good!

It just makes you want to listen to the music - on and on. I am sure this is to do with the implementation of the flagship RoHM BD34301EKV chipset. If you like to listen to music - and looking for a very good DAC at this budget and beyond, buy it!

If you are looking just for impact from the first few notes of a song and impress your friends, maybe something else!

The chassis, some say (online) is a bit flimsy, but I find it fair enough - to keep the prices down. This DAC is a keeper!
