I often come across comments like “vinyl is cut from digital.” First of all, that’s not necessarily true — at least not for the records I buy, or the ones most vinyl lovers on this forum tend to buy.
People favoring digital think that they’re listening the purest, identical digital file as the master. More importantly, I’m always amazed by the naivety behind these statements — as if producers would ever let the exact digital master leave their vault unprocessed. Do people really believe that the original digital masters are uploaded directly to streaming servers? Do you think the FLAC files you stream haven’t been processed or encrypted in some way? Or FLAC is lossless?
This reminds me of the old debates about CDs. People often assume it’s just simple ones and zeros, without understanding how many layers of processing and encryption digital audio goes through before it’s burned onto a CD. There’s absolutely no direct relationship between the original digital audio file and the CD you buy. Sure, they can be mathematically identical after processing, but in their stock form, the data is different. The same applies to streaming and downloads. Digital audio passes through a huge number of processes from the server to your streamer — and those processes can negatively impact sound quality.
If you disagree, then explain this: why do switches, LPSUs, and digital cables (Ethernet, USB) make a difference in your home setup? Why do those things matter, while thousands of miles of cables and countless chips along the transmission chain supposedly don’t? If digital processes like encryption and decryption don’t affect sound, then why do we hear differences between better DACs and cheaper ones?
The main problems are:
- You’ll never get access to the actual digital master file — not through streaming or downloading. No producer will let you have what he/she paid a lot of money to have. Maybe if the producer personally brought it to you on a hard drive, it would sound incredible — but that’s not what we get.
- Streaming and downloading involve transmission over the internet and require multiple stages of digital processing, including encryption and decryption. These processes degrade sound — possibly even more than cutting vinyl directly from the digital master file would.
