Tversky's colleague Daniel Kahneman's fun book "Thinking Fast and Slow" is a good read for the layperson.  Talks about many issues which, I think, apply to audiophile nervosa.  Kahneman says several times that Tversky would have shared the Nobel prize with him, if he had not died prematurely.

This is indeed a fantastic book.

It also occurs to me you could take the vinyl file and do a brickwall high pass filter at 30 hz and see if the DR value starts to approach that of the CD.  That would let you know it is being modulated by some low frequency speed variation.

 

 

Here are screenshots of DR states from LP rip The Crusaders - Images (1978, USA).

The whole process: from recording without RIAA (RAW)  and to converting (SRC) to CD format):

 

1. The Crusaders - Images (1978, USA)  (Raw)

2. The RIAA curve is applied and cut into separate tracks

3. Gain Output Levels (software): Side A - 3.39dB and Side B - 3.84dB

4. Gain Output Levels (software): separately each track

5. Conversion (SRC) of tracks to the quality of CD (16/44.1)

So now put a steep filter in to roll off everything below 30hz on the 16/44 file and see if that reduces DR ratings.

And always keep in mind: Cognitive biases, like seeing optical illusions are a sign of a normally functioning brain. We all have them, it’s nothing to be ashamed about, but it is something that affects our objective evaluation of reality.

Ok, I applied a steep filter of 30Hz and added a "brickwall" to all 16 / 44.1 files. I used this software:

30hz01.thumb.jpg.d4cef8a13ab7d4af643a1cff9330a3f4.jpg

 

Here is the result of DR measurement:

So that does not appear to be why the DR reading is different by so much from the CD.  Thanks for doing this.

"Please take this day as an opportunity to rediscover one of your favorite albums that was produced with dynamics in mind and think, What if they all sounded this way?"

 

This happens every time I play an electric guitar lead blues group on one of my AudioQuest Music SACDs, which are similar in style and have many of the same instruments as electronic rock music.  I wonder why rock music isn’t recorded this way. 

 

It’s not just the severely limited dynamic range of major label recordings, it’s all the tools they use to alter the sound, which IMHO destroys the feeling of listening to actual music.

 

I question the value of most high resolution music files from the major and other non-audiophile labels, since most of them don’t even challenge the capacities of CD format. And many modern major label recordings don’t even challenge the MP3 format IMHO.

 

I find the audiophile remasters of major label recordings (MFSL, Audio Fidelity, Analogue Productions, etc.) to be more to my liking than the originals however I don’t purchase them anymore as I find authentic audiophile recordings (audiophile from the microphones to the finished product) to be more enjoyable and sound superior in every way. Some of my favorite audiophile labels besides AudioQuest Music include Reference RecordingsChannel Classics, pre-2009 Telarc especially their Pure DSD SACDs, as well as about 50 other audiophile labels.

 

High resolution digital doesn’t guarantee more realistic sound quality, it just offers the possibility. IMHO this is something seldom achieved, however when it is WOW!


Instead of recording all the musicians playing together in a good sounding environment using two tracks, most modern recordings are extreme multitrack affairs using partitions to separate the musicians requiring them to wear headphones to hear each other. This allows each instrument and voice to be edited separately to further destroy spontaneity and move it further and further from reality. 

 

I no longer buy major label recordings.

 

I have dementia. I save all my posts in a text file I call Forums.  I do a search in that file to find out what I said or did in the past.

 

I still love music.

some of this damage can be undone using audacity + plugins

"engineers" do the damage in the digital software domain so non-so-surprisingly you can kinda attempt to undo it that way

https://demaster-nsfl.blogspot.co.uk/

see my blog (which needs like minded visitors)

examples from the flaming lips "yoshimi .." album before and after my processing. worked out good. not all work out that way.
