Little Giant NOS DAC mini review


I bought this dac a few months ago from Aliexpress. It is a 47 Labs clone with a Philips TD1387 chip in non-oversampling mode.

It also employs a variant of the Pass output buffer, and utilizes a sole S/PDIF coaxial input.

When using this dac with my computer, differing levels of digital distortion were clearly present, with the best digital files having the least. The results were good to terrible.

But when I use my Carver MV5 cd player as a transport, I get much different and improved results.

Not only is the distortion reduced to a tolerable level, the sound is warmer and smoother, with a good soundstage and imaging.

I would also say that it is closer to analog than my old Micromega Stage 3, while providing more air and apparent resolution.

I have indeed done such tests to determine which formats are truest to the source. While we didn't have high order dsd back then, but we did have access to the best recording technologies and equipment.

 

The tests involved musicians playing live acoustic instruments, recorded in both analog and digital (to dat), and played backed thru what we felt was the most transparent system we could assemble (including headphones which I still use to this day).

 

In one session, we were blessed to have access to a direct to disc setup (cost us a small fortune), which clearly rivalled the best analog tape recordings, while being nearly indestinguishable from the original performance.

 

But the digital captures were clearly the least accurate of the recordings, sounding noticably and distinctly different from the live performances, which were all compared directly in real time.

 

To this date, I have not seen or heard of a single digital technology that can capture a live acoustical event accurately. High order DSD is the closest, but it lacks the critical inner detail to successfully pull it off.

It can certainly be interesting and fun to get an upgrade in systems sound with ‘affordable’ gear. What’s even more interesting is how we get used to that sound over time and then can upgrade to a ‘better’ sound over and over and over. I once felt I had an awesome system that seemed like it had a great hard to achieve balance of a couple key traits. I am a couple/few price points above that now and could not go back… But it is always fun to find that pleasing facsimile-of-reality that sings with the given gear. There’s always more… 

The state of the digital art and design has changed almost exponentially for the better over the last decade or more.  Several years ago with my ~$25K analog set-up, I really enjoyed analog over my digital sound which also wasn't cheap.  However that all changed with a relatively inexpensive DAC that uses an older non over-sampling no digital filter chip and a really good power-supply.  It took my digital listening to a whole new level.  I found myself listening more to digital and less to my analog set-up.  As time passed, I sold my whole analog set-up and went fully digital and every step up the digital path since has shown me improvement with each change.  The key in my opinion for improved digital sound quality is to minimize noise and jitter in the digital path, and there are a number of rather inexpensive components that can get you there.
