MoFi controversy


I see this hasn't been mentioned here yet, so I thought I'd put this out here.  Let me just say that I haven't yet joined the analog world, so I don't have a dog in this fight.

It was recently revealed that Mobile Fidelity Sound Labs one step LPs are being cut from digital masters (DSD) rather than being straight analog throughout the chain.

Here is one of the many Youtube videos that discusses it

 

To me, it seems that if MOFI is guilty of anything, it's "deception by omission."  That is, they were never open about the process and the use of digital in the chain. 

One thing to mention is that hardly anyone is criticizing the sound quality of these LPs, even after this revelation.  Me personally, I wouldn't spend over one hundred dollars for any recording regardless of the format.

@atmasphere and anyone else who might know. You mentioned when you were cutting LPs:

digital release files are compressed since there is an expectation they will be played in a car

Is this still true today, especially for modern high resolution digital files, for instance those that are offered on hdtracks or on SACD? I know most modern pop music still doesn’t have high dynamic range, even when pressed to vinyl, but there are still a number of productions across genres that strive to preserve the integrity of this range.

If what @mceljo is saying is true about SACDs having greater dynamic range than vinyl (which seems plausible), and say the digital playback chain (clocking, DAC’s digital chip and digital implementation, the DAC’s analog stage, low noise, etc) is of a reference quality, then this would mean that there really is no benefit to playing the vinyl version of same mastering regardless of how great the pressing quality is, unless the listener prefers how their cartridge and phono stage sounds over their DAC or “prefer the distortion characteristics built in to record playback that are pleasing” as @jallan says, right?

Under these specific circumstances, there is really no possible benefit to the vinyl? Or am I missing other variables to consider?

I’m not trying to argue this in a “one is better than the other” manner, but just trying to understand the full picture for consideration. Thanks.

Whether an uncompressed digital source file was used for the LP mastering is another matter entirely and depends largely on the producer of the project.

Thank you Ralph (@atmasphere) for this very informative post in its entirety and for your particular comment above. Moving on from redbook vs vinyl, do you have any thoughts on the dynamic range of high resolution files (considering they were produced to take advantage of the range) and its performance in a low-noise, caching local server with a stellar clock and architecture? Yes I know that many digital front ends aren't up to the task, but there are a few that I believe are.
