Debunk Pseudo Science Claims

 Is there any audibly transparent DAC? Yes or no? TLDR: According to  SMSL SU-10 DAC Review | Audio Science Review (ASR) Forum , the above DAC is considered as "audibly transparent" by those "Audio Science" guys.  Amongst all the DACs they measured (as of today, 8 June 2024), its SINAD is ranked the 1st as shown below: Does it really mean such DAC is audibly transparent? Before we can answer the question, let's look at the definition of "audibly transparent" DAC again. What is the definition of audibly transparent in general public? If you ask the general public who has Hi Fi system at home (here we are talking both Audiophiles and non-Audiophiles general public), they would give you something like the following for the definition of audibly transparent: Audiby Transparent is the holy grail they are looking for. If a DAC is audiby transparent, it means it does not introduce any audible sound of its own and reproduces the audio signal faithfully. In oth...

Seeing is believeing? Another trick of Pseudo Science: Demo TLDR: Analog or Digital? Magic? Source (at 4:33  D/A and A/D | Digital Show and Tell (Monty Montgomery @ xiph.org) (youtube.com)  ) How often you see a "perfect" and "smooth" sine wave on an oscilloscope (as shown above) when someone was attempting to "prove" that CD-quality music can reconstruct the analog output like the original.  To quote the exact phrase, " the analog ouput is still a perfect sine wave exactly like the original " (at 5:04  D/A and A/D | Digital Show and Tell (Monty Montgomery @ xiph.org) - YouTube ) Someone may said, "Yes, that's a perfect sine wave. Everyone can see a smooth sine wave is reconstructed from CD-quality digital input. Don't you see it? I can use an oscilloscope to reproduce the same thing myself to verify it." Hmm.. that's the art of Pseudo Science . They attempt to show "factual evidence" in front of you and tell you t...

 Another major characteristics of Pseudo Science: Naming. What is "audibly transparent"? TLDR: Naming   is another   art of Pseudo Science .  A forum named as "audio science review forum" or "sound science forum" doesn't automatically mean its contents / claims are based on objective scientific evidence. Most likely than not, these contents / claims are questionable as they are based on pseudo science " evidences " . Audibly Transparent Let's have a look of the term "audibly transparent". I did try a search ( Search results for query: audibly transparent | Audio Science Review (ASR) Forum ) on the term "audibly transparent" on ASR. I found there are a lot of discussions / usage about it: One of the famous thread there is  Serious Question: How can DAC's have a SOUND SIGNATURE if they measure as transparent? Are that many confused? | Page 468 | Audio Science Review (ASR) Forum . It has 468 pages already and keep goi...
