Audio Science Review = Rebuttal and Further Thoughts


@crymeanaudioriver @amir_asr You are sitting there worrying if this or that other useless tweak like a cable makes a sonic difference.

I don’t worry about my equipment unless it fails. I never worry about tweaks or cables. The last time I had to choose a cable was after I purchased my first DAC and transport in 2019.  I auditioned six and chose one, the Synergistic Research Atmosphere X Euphoria. Why would someone with as fulfilling a life as me worry about cables or tweaks and it is in YOUR mind that they are USELESS.

@prof "would it be safe to say you are not an electrical designer or electrical engineer? If so, under what authority do you make the following comment" - concerning creating a high end DAC out of a mediocre DAC.

Well, I have such a DAC, built by a manufacturer of equipment and cables for his and my use. It beat out a $9,000 COS Engineering D1v and $5,000 D2v by a longshot. It is comparable to an $23,000 Meridian Ultradac. Because I tried all the latter three in comparison I say this with some authority, the authority of a recording engineer (me), a manufacturer (friend) and many audiophiles who have heard the same and came to the same conclusion.

Another DAC with excellent design engineer and inferior execution is the Emotiva XDA-2. No new audio board but 7! audiophile quality regulators instead of the computer grade junk inside, similar high end power and filter caps, resistors, etc. to make this into a high end DAC on the very cheap ($400 new plus about the same in added parts).

@russ69 We must be neighbors. I frequented Woodland Hills Audio Center back in the 70s and 80s. I heard several of Arnie’s speakers including a the large Infinity speakers in a home.

@td_dayton 

i'm very impressed with your credentials. but i'm on my own path. you don't need to worry about what i'm doing. we don't even like the same music, why should i care what you think? etc etc

 

No one is suggesting for one minute that you (or anyone else) has to.

The important thing is that the data is out there and available.

The rest is entirely up to the individual whether they want to make any use of it.

The same goes for published online and magazine reviews.

 

When someone is seated at the piano, we are generally not debating whether person A is hearing a piano and person B is hearing an organ or a flute. There is little debate and imagination as to a piano being a real thing, and its sound being a real thing.

 

They do imagine it. Our senses are imaginary at a very basic level. That’s why a machine doesn’t replicate what we “hear.

And hence the measurements tell us how closely a playback of say a piano sounds like, say… a real piano.

We do not care whether person B hears a piano sounding like flute, we only care that it is replicated correctly.

To talk about brains and personal experiences is delving into psychology and neuroscience, whereas the playback system is electromechanical. We have to draw the line somewhere.

To talk about subjective differences in hearing, is burying one’s head in the sand as to the reality of what is happening.
That thinking belongs in a course on philosophy and not in engineering or physics, and hence it belongs in a coffee house and not in an audio shop or engineering laboratory.

And hence the measurements tell us how closely a playback of say a piano sounds like, say… a real piano. We do not care whether person B hears a piano sounding like flute, we only care that it is replicated correctly.

 

if you need measurements to tell a piano from a flute, then I don’t know what to tell you… Maybe take on another hobby?

 

 

@cd318 exactly - & that's why i have no quarrel on principle with more objective minded approaches to evaluating gear. people are doing their own thing. some prefer to approach it from a purely "show me the evidence" engineering sort of perspective, while others would rather primarily rely on their senses first. i lean towards the latter but there is obviously real value in the former - after all, this hobby wouldn't exist if it weren't for the efforts of a century-plus worth of electronics nerds. ultimately which "camp" people fall into makes no difference to me because at the end of the day, if i'm drawn closer in to the music, i'm happy. we should all stop playing stereo cop and just accept that different people value different things in their gear. just my .02c

if you need measurements to tell a piano from a flute, then I don’t know what to tell you… Maybe take on another hobby?

Sorry @thyname but I am person A in the above scenario. so I cannot speak to what the person B’s hearing.

Maybe take it up with @prof  or @cd318 
I think they both were responding to your posts earlier, and my comments stemmed from those.

This one of their’s was a pearler.

Now it would appear as if all of those differences were largely in our imaginations and have now become as irrelevant as the use of leeches has in healing the sick.

again - I don’t care how you hear, or what you hear… I just want whatever I play to sound like the recorded sound.
