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.

I purchased the Yes Fragile MoFi  One Step record. I have almost every version of this album from the MoFi Gold cd, to the Blue Ray, the Atlantic cd's and record. None come even close to the One Step. On my MoFi  Ulra Deck turntable the sound is second to none by a huge margin. The guitar on Mood for a Day sounds like it's in my room with me. It has more body, texture and realism, that makes every other version sound disappointing. You also need a really good phono stage. I have a CAT preamp.

Optimize, you cannot possibly still be arguing that even RBCD, played on a home CDP, is superior to high quality vinyl reproduction. Can you?

@lewm why couldn't I?

It is not my fault that people compare compressed source material against uncompressed and they think that they compared appels to apple?

I could say the same 

You can't compare lossy LP production to lossless CD?

 

Ok let's take another angle..

If LP production process steps were lossless why do MoFi need to do several test pressings from their 4xDSD?

They should be able to just EQ and make the DSD as they wanted to sound and send it directly to production, done deal.

No the problem is LP production process steps subtracting sound quality and attenuate some frequency range more than others.

That is ONE reason that they do test pressings. So they can listen and analyze what has been attenuated and then they can boost the DSD file accordingly so the NEXT test pressing will supposedly sound as they would like it to sound from the new adjusted 4xDSD file..

In other words they adjust the 4xDSD file as a tool so they can work around and compensate for the degradation that the LP production process steps introduce.

 

But I can't understand why it is so hard to understand that?

I am a huge vinyl lover but I do not pretend that it is something else that it isn't. 🙏💕🎶🎼🎵
