An interesting note, those Mitsubishi digital recorders had a sampling rate of 50.4 KHz, compared to later recorders with 44.1 KHz and the iindustry standard 48 KHz sampling rate. What was the sampling rate of those early Decca, Soundstream and Denon digital PCM recorders?As far as I know these Mitsubish recorders were only available in 1980. Decca , Soundstream and Denon predated them.
I don’t understand why you don’t understand this!I don’t understand this. Thriller was released in 1982. How was the “original source” a digital file?
Yep: The Dawn of Commercial Digital Recording.As far as I know these Mitsubish recorders were only available in 1980. Decca , Soundstream and Denon predated them.
Decca made their own digital recorders - modified a JVC video recorder. 48/16. When they were bought by Polygram in later 1980, they had a big fight with Philips which was using the Sony 44/16 system. Decca kept their system. I interviewed the Decca engineer who developed their system for my Decca book back in 2014. Their digital vinyl releases all used their system and they had to send their machines to Baarn so that Polygram could decode their Decca's digital files for conversion to CD's.An interesting note, those Mitsubishi digital recorders had a sampling rate of 50.4 KHz, compared to later recorders with 44.1 KHz and the iindustry standard 48 KHz sampling rate.

If they are using 4x DSD there shouldn't be any buildup of noise until 70-80khz. A 30-50khz bump indicates single rate DSD. I'm guessing that this was sourced from their SACD master.To my credit (toot toot) I knew something was up. I just didn't know what, because my assumption was the OMR meant AAA. I rip all my vinyl and then analyse the results so that I can try to get some idea of provenance.
AAA titles typically look like this. The spectrogram is always clean.

Whereas here's a MoFi (Love Over Gold). Lots going on here. The demarcation at 30kHz. The elevated noise between 30kHz-50kHz (now we know this is DSD ultrasonics). You simply don't see this kind of spectrogram with AAA material.

This would have been some variation of the Gain 2 Ultradisk system they used for SACD: single rate DSD with EMM Labs ADC converter. Those SACDs still sound great, by the way. It also makes sense since they released an Abraxas SACD as well.According to MoFi engineers they began using digital in their vinyl reproduction in 2008; i.e. Abraxas was sourced from the 2008. It may not have been DSD256, but according to the engineers digital was being used and if it wasn’t DSD256 then it must have been something worse?

Yeah, they were pretty slippery when advertising that their cutting process is all analog, while hiding the fact that the actual mastering is DSD.Thanks. It’s not the SACDs I’m questioning, it’s MOFIs production of vinyl using digital without informing anyone.
I'm going by what's on their site the other stuff is noise.You missed a few things. There were inserts shipped with some records indicating all analog. These records are now known to have been cut from digital files. And you've got a Mofi mastering engineer on video unfortunately lying about specific record(s) having been all analog when it is simply not true. Besides that, the advertising is simply deceptive to a degree that other labels don't seem to be. I have no horse in this race, and don't have but a few of their records, but Mofi screwed up big any way you look at it.
I don't think there's any interest here for that in this thread Brian. I've been vocal against all audiophile labels for a very long time I've my posted my arguments in many threads in this forum. My mind set is very different from people who're willing to pay premium for a MJ record printed in tens of millions that one can find even sealed originals for not much just because someone stuck an "audiophile" in there, they don't want to hear from me no more than you wanted to hear what I had to say about streaming .Tell me more about noise filtering and 180g records. That sounds like a far more interesting topic of discussion at this point. In another thread.
Mobile Fidelity storm in a teacup
I have seen this topic blow-up all over the place. Yes, Mobile Fidelity have not been transparent with the process they use to make their records, yes that is out of order. But the way people are going on about this, you would think it’s the end of the world. This is real first world problems and frankly it’s laughable.
Some of the words I have read and videos I have seen, frankly makes me want to laugh my head off. People feel like they have been deceived and some are going to dump records they have had and loved for years, seriously if they have enjoyed it for years. What has suddenly changed, does it not sound as good as they thought now Just because they now know it may have digital steps in the process?
People moan about resale value will be low, for me personally I don’t buy music for the resale value. I buy the music I want to listen to and enjoy, with no intention in ever reselling.
If those people stick to their words and start dumping their MoFi’s, the rest of us that just want a good sounding records can pick up bargains and not have to pay as much for them. I am all for everyone dumping their Mofi’s. Please start dumping them.
All this uproar about Mobile Fidelity, Apple is another company that has been treating their customers with contempt for years. Do this people say I am never buying Apple products again, hell no they say please Mr Apple take more of my money.
This video made me laugh

There must be a lot of hurt pride in people who were swearing that analog was so superior, and now discover that all their beloved vinyl records were digital...
Perhaps digital is fine after all...no, can't be!!
If vinyl provides a nice coloration that makes those digital files sound good, so what?
According to your reasoning even fake vinyl sounds better than your pure digital.
The only company I have some trust in for being AAA would be The Electric Recording Co, but I think they’re assholes the way they run their model.
