All modern analog recordings were originally recorded on analog magnetic tape. Magnetic tape has a form of "sampling" by virtue of the recording media. Magnetic tape is composed of millions of microscopic magnetic "dipoles" and these dipoles individually "record" a "bit" of the waveform amplitude at that instantaneous moment. And then, the playback head gap determines the "resolution" of how finely you can "resolve" those magnetic dipoles and what magnetic field each of them have. Those of us who actually understand what is happening with analog don't have the same fascination for that antique technology.

Not many even cherished 80s recs were done using full analog chain. Even early to mid 1980s. artists and producers were recording to and mixing/mastering in digital: think Sony PCM-1610 or DASH multtrack recorders.

The evolution of analogue systems moved forwards to remove distortion created by the hardware and get to get as clean a signal path as possible. Digital systems provide that clean signal path but then we realised it was the distortion and saturation of analogue that give it that pleasing warmth/3D like sound (whatever). It all boils down to this fact: IMPERFECT analog circuits imbue an essential "organic" quality to music reproduction (literal errors) that are lacking in "sterile" digital chains that are more transparent and closer to the original SOURCE MATERIAL (no matter is it analog or digital).

Ironically, many vinyl presses in the 80s had a digital delay unit placed in the chain - the output that was pressed to vinyl while the mastering engineer adjusted the input signal in realtime during cutting. Even those warm "analogue" 80's presses everyone cherishes so much were converted to 16 bit digital during the cutting process.

Your cherished 80s "analog warm recordings" are literally converted to digital during the cutting process
