OK. I was not sure that I should reply... and what exactly to answer... but here we are for a Friday night response:
1) Your link did not answer my question about how do your personally actually distinguish the "dynamic range" of different DAPs to select better ones from unnecessary expensive - I would really love to learn how to do it.
To digress into your old 2011 reference - back then the music industry was "on board" with DSD - to sell the same music to consumers in different "high-res" formats - SACD, DSD, etc.
Nowadays, the predominant mode is the "pay per use", so mp3/aac became very much acceptable (as they should) not to cram the downloads with unnecessary bits and bytes to provide those "150 dB" that we'll certainly get to in 3).
2) I am not sure why you mentioned your degree. Do they teach science differently in this program? (Self-censored this part not to go more into it...)
The science is indeed about parameters, reproducible measurements and math; and more so is the engineering - so that is why any management can't compensate for the current chip shortage that you've mentioned - to make chips, IEMs, amps requires tangible well-defined skills based exactly on those reproducible parameters.
3) I hope you never experience 150 dB (even 120 dB) - it will be mind blowing, not literally, but physically!
So if you take your favourite music and spread the dynamic range to 150 dB, it will be painfully unlistenable, as simple as this - the experience better not to be experienced. So 16 bit is perfectly enough, 24 is already redundant, but is often used for mastering to have some room for mishaps.
DSD is an interesting format, but given that it is not directly equalizable and do require more processing power for a hardly tangible difference - I personally will not bother to use it. With the lossy "audiophile" formats, MQA is struggling for their "claim to fame", as long as there are those who are willing to pay...
Lastly, your subjective experience is valuable and important, but trying to defy science based on personal feelings is just futile - this much should be painfully obvious, as those large dBs, where bigger is not better
Not gonna dig in too much:
1) it’s not my assignment to walk through how DAP works, but you may take a look the circuit designs of BTR5 compared to ones like Shanghling M8, DAC, FPGA, Amps. They have different streams of processing digital to analog conversation. BTR5 is good amp indeed, just like VW Golf GTI for car, small and agile. But Golf GTI isn’t a Mercedes AMG E63S killer. They simply perform at different altitudes.
2) You speak as if I don’t have any scientific background, so I was just addressing I have the background. Science is a mean of catching strings from math/formulae, but I’m saying even at the best of best MIT, we are not able to “code” organic living things. Audio science is not as expensively studied as quantum mechanics, it has huge room to improve, I’m just saying, I’m not participating in this area though. I still want to leave audio into some non-science “feeling” domain.
Honestly are you listening music by numbers?
Like “Hmm! This third harmonics of G7minor code sounds so fantastic! Love it!”?
I don’t think too much about analytics when listening music, it’s a feeling domain.
For dynamic range illustration difference, It’s about same difference that can be visualized as dynamic range illustration on screens, it just a matter of it be on screen or in your ear (assuming proper DAP / Original mixing and mastering /IEM/ Tips/Cable is used, with only difference in sourcing format)
3) again, I’m not science noob, so this is redundant explanation to me. I play drum and can get quite loud close to 120db. Surely it hurts but I’m still alive by that 120db shock wave.
Each 10db it get double magnitude, amplifier with proper FPGA clocks with well tuned analog converter simulates better illustrations. It’s not too hard to compare good recording to tell BTR5 compared to M8. There are 10% of margin in sound quality improvement. You will surely admit that 10% improvement is inevitable difference of $100 player compared to $1600 one. Just a matter of willingness to cope that gap though. If your brain tells 16bits sound exactly same to 24bits, then we have no room to discuss...they sound different to my ear.
For audible frequencies, yes, by “current science” we are not supposed to hear above 20khz. Human were believe not sensitive to magnetic field. Not until recent researchers found human eye has a same sensor with birds, and is capable of seeing magnetic field. Our close relatives, Chimpanzees can hear sub-bass frequency which human are not “attested by current measuring equipments” to hear, that by science does not guarantee human can not hear “inaudible” sounds. Don’t mistake reality by a way of recapturing it(the
).
You don’t need to limit human capability by existing theory, there is a room for extra assumptions. Maybe you work for experimental science domain and not a theoretical science fan, but we can agree science is not a perfect book, it’s just an approximation.
Again, I’ll emphasize, Science is just an approximation of real world.
Don’t mix this factual circumstance, Science does not equal to real world.
We use thing without knowing real logics behind, taking example of anesthesia. Not until very recent we found the logics and hints of the mechanism of anesthesia. That does not mean anesthesia is ineffective to relief pain until human “observe” the mechanisms behind.
Same to music, there are lots of undiscovered mechanisms beyond how music can affect living organisms, some study shows even plants are not out of scope to music. Some study shows music helps to synchronize the participants brain waves. We are just so behind the actual cause. You seemed limiting yourself with only observed scientific factual figures, it’s your own way of living, but hope this remind you there are thing beyond border line of modern science could solve, music is one of the those.
Try take MBTI test, I have a feeling you are ISTJ type. I’m INTP type, so we work under different principles. My main inputs are through intuition then logically processed to various outlets.
And let’s stop this off-topic discussion, it’s pointless, just enjoy your music, if you love science to back up your perception, so be it. You may contribute to open a new frontiers indeed
