Each to their own, but measurements don't lie - CD is far more accurate (and longer lasting) than vinyl.”
I agree, wear on vinyl does destroy the top end frequency response. Hence CDs are longer lasting nd is why several serious audiophiles I knew would take their fresh LP and record the first play to reel to reel, preferably half track and certainly at 15ips. Whether the inevitable small amount of tape hiss would compromise that ...... But then of course there was DBX with the additional compromise of encode / decode.
And now we've opened up the can of worms.
At the opposite end of the spectrum CD can more accurately low bass, anyone with less than a stellar turntable trying to reproduce the Telarc recording of the 1812 Overture will remember the stylus flying out of the groove when the cannons fire.
Equally anyone with less than a stellar audio system will remember the damaged speaker cones when the recording was finally released on CD.
Vinyl was, on a good day, and with a PERFECTLY set up turntable /arm/ cartridge combination could expect 25kHz out of vinyl (the odd exception being Shure cartridges, never known for their wide FR) and 30kHz (with admittedly substantial roll off) could be achieved ( the frequency used for CD4).
HOWEVER, I realised many years ago - during the pursuit of increasingly exotic audio - that I was spending more time listening to the HiFi than the music it was reproducing (and countless hours fine tuning turntables). Now I except the limitations of both and instead of spending £1000's on audio components I plough that money into music, and I'm happier for it.
But for anyone interested in music reproduction, the effects of frequency respone and harmonic effects on instruments you can always check out the work of Prof Hawksford at Essex University who did a lot of work in the mid to late eighties on precisely this topic - his ideas where adopted by many audio companies and the APRS.
