LP made from a digital master recording...

When an LP is pressed from digital...it is played back as a continuous waveform. That might be a benefit of vinyl. If you listen to a record the 2nd time, it will not be the same performance as the first. With digital it will be the same the 2nd, 3rd and 100th time...for good and bad.

My non-scientific guess, is that when the vinyl plate is cut by the cutter head, there is some loss and gain in the detail/fidelity but also it is now a continuous format. The cartridge is a dynamo that will reinterpret the music.  Think of redrawing something rather than scanning something.

When you play vinyl it's sort of an original performance each time, isn't it?

Yes I suppose nothing is ever the exactly the same twice if you drill down deep enough.  BTW, I have nothing against digital...I enjoy both. But I, like a lot of people, do think vinyl is more musical (and magical).  I think the best form of digital will be outdone by the best form of analog any day because there's less 'there' there. It has survived the reel-to-reel, cassette tapes, 8-tracks, CD, every kind of current digital format for a good reason.
