Perfectly reproduced music does not exist. Some digital medium have the potential to offer great performance, does not make it perfect, streaming is not the best digital experience anyway. don’t drink the kool-aid.
When I retired I did some experiments to see if some of the audio myths were real or not by checking what level of distortion I could hear and the dynamic range I needed for the music I like.
There is no left doubt in my mind that CD is audibly transparent, for me, from this, so I would say CD is
perfect reproduction.
The problem is there is no such thing as a
perfect recording.
CD has a flat frequency response inaudibly low levels of distortion and a frequency response that goes higher in frequency than I can hear, so “better” reproduction than CD is completely pointless IME.
The thing with LPs though is that very few cartridges have a flat frequency response, quite a lot (probably the majority) of turntables used in the listening room pick up enough spurious vibration in the environment to add a nice bit of reverb so with LPs one can dick about with the sound to suit yourself whereas with CD you are stuck with listening to exactly what the record company released. The dynamic range isn’t a wide as CD but is usually enough. Distortion is sometimes audible, depending on modulation and where on the disc but is rarely enjoyment ruining for me.
All 4 of my turntables sound different.
On good recordings they can sound sublime.
On bad recordings they are awful.
All my CD players sound the same but the limit is still the recording, with good ones sounding sublime and bad ones awful.
For me it is pointless getting tribal about LP versus digital since the limit on SQ is recording quality not ones HiFi.
Which is a shame if you are a Hi-Fi nut but still true
