@aberyclark , neither Philips nor SONY invented DSD. Philips was the first to work on applying it to modern audio. Sony jumped on and they created the SACD standard.
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.

@theaudioamp I guess that is the "thing"...Are we kidding ourselves that our ears can hear the difference in CD quality versus anything with more resolution? But if studios are recording in 24/96 it would seem best if we could buy the files in that native format or stream them. |
To understand why, a professional tape recorder provides the most lifelike reproduction revolves around a couple of important factors. The key lies in the inherent technology of the tape itself. Audio tape in use during the 1950s and ’60s provided approximately 65,000,000 magnetic particles per second of recording a quarter inch format at 15 inches per second (ips) tape speed. Each magnetic oxide particle or groups of particles takes on either a north or south orientation after exiting the recording head. Starting to sound like digital bit stream? Well yes and no. However there is one huge difference between analog tape recordings and even the best digital recordings. RESOLUTIONThe highest digital resolution today offers 4,608,000 bits switching per second. Not bad. Big improvement over the standard Red Book CD but it is not even close to sub-micron particle resolution of ATR Master Tape. RANDOM PARTICLE STACKINGQuarter inch, two track ATR Master Tape running at 15 inches per second (ips) involves approximately 80,000,000 oriented and randomly stacked particles per track second. It’s not just the particle count but the random stacking that turns this super binary resolution into pure analog playback. This is why even a narrow track width recording still sounds so detailed despite the lower surface area. Music is an intrinsic part of the human soul. It plays to our emotions, it talks to us, it calms us, it makes us rise to our greatest accomplishments and brings back our warmest memories. Why not record it on the best medium to achieve the best quality of sound? |
