How can DAC's have a SOUND SIGNATURE if they measure as transparent?

AI calculates that if you are listening at 10 feet, a 0.1dB increase in level occurs if you move your head about 1 3/8 inches toward the speakers.
Easier to test yourself with a set of headphone using the link I posted originally. My experience was that downward detection was much more difficult.
 
All you humans should be kind to AI because it's maturing in to AGI and you will be like ants to it. So in your own self interest please be kind to AI.
 
In this case AI got it right.
Let's test that in real life. :cool:

For spherical wave in a free field,
Ah, so not anything that any of us ever do then?

...the sound pressure is proportional to 1/r.
Therefore, the ratio of the sound pressure at 10 ft and 10 ft 1.375 in is: (10*12 + 1.375) / (10*12) = 1.01146
Convert to dB = 20 log10( 1.01146 ) = 0.099 dB ⫽
The framing of the statement was directed to what 'you' hear when 'listening to speakers' when 'you move your head forward'. (generic 'you')

Generically, we listen to music in rooms. Suddenly, everything changes about that calculation.
  • The walls/room are often contributing about as much energy as the speakers' direct sound. At some frequencies the SPL we receive from the room won't change at all with a small head movement. At other frequencies room modes could make a much bigger change than 0.1 dB with a small head movement.
  • Also, at most frequencies, most of 'our' speakers are not radiating spherically. So the answer changes with frequency.
  • If the couch is close to the back wall (a bad thing, but a common thing), then moving 'our' head forward could cause a bigger SPL drop than the gain from moving closer to the speaker.
  • etc
I reckon that there is no practical connection between the AI statement and reality of 'our' listening circumstances.

cheers
 
What do you say about this expert what says if it measures well and sounds bad, it's still bad: https://pt.audio/2025/05/15/kt88-vs...il&utm_term=0_5454ba75df-ca001b70d1-592433153
I'd say that's a question loaded with a contradiction in terms big enough to disqualify someone from "expertise" on audio electronics.

If you prefer some sort of colored, non-accurate reproduction, well, that's outside the purview of objective performance, but anyone who extends this to "fidelity is bad" needs to get over themselves.
 
What do you say about this expert what says if it measures well and sounds bad, it's still bad:
What is it, a DAC? A DAC needs to be very broken to "sound bad".

Whilst Kevin Hayes knows his stuff on tube amp design, much of what Kevin Hayes says is often audiophile pseudoscience or romantic marketing rather than engineering.

The problem is he's both an expert and a salesman. He reckons he can change the sound of his amps in ways that can't be measured (6 minutes or so in).

But, like every amp designer who makes that claim, he does not support the assertion with blind tests.

It seems my opinion about audible differences in DACs with high SINAD are shared by Robert Harley Editor of Absolute Sound.

This one needs a summary too...
 
Looks to be another thread whose time may have come...

The OP orphaned it after a couple of days and has not been seen in years. Am putting it up for adoption.

New thread manager would need to be a donor member in good standing with demonstrated ability to be objective and fair. PM me if interested before June 1. :)

Cheers to you for closing zombie threads that rehash the same old garbage arguments. It's long overdue on ASR. :)

There have been multiple threads on more or less the same subject (someone says they hear something in DACs that tests do not show). I think that having this thread around, and merging new threads as they show up into this one is nice. That way this subject matter is easy to ignore, and it serves as a good hint to the OP-to-be that this subject is debated to death already.

While I agree with the premise of your proposal, it has to be managed. A thread with over 500 pages and almost 11,00 posts is not a great starting point. Would a new member or viewer be motivated to slog through all of this? I doubt it. Adding to this thread is like arguing in favor of gifting to a hoarder. While there might be some good stuff in the house, unlikely anyone wants to go through the mess to find the good stuff.
