1. Not true. You are mistaken how Nyquist works. You need a sampling rate at twice the highest frequency. 50khz = 100khz sampling rate which is over twice the resolution of CD.
2. There is no dynamic range issues with modern analog rigs. CDs perform better in this area technically but I have never heard even the most dynamic music like orchestral suffer in any way to even reference CD playback such as my friend's $14K Wadia player.
3. No doubt there are mechanical distortions in LP playback but are they sonically audible? On a fine turntable I have my doubts.

But, it really never accurately play any above 20kHz due to very obvious limitations. (one of reason why CD-4 was made, was to handle information accurately to 45kHz) And no, I am not talking about RIAA curve. I am talking about the process on mechanical/manufacture respects. And no again, you only talked half of the problems of why Vinyl cannot properly play treble. Way too many end-user playback devices attenuate those high-frequencies (which is smart, since those high-freq information is terribly inaccurate in the first place) thus there is little/no/worse performance compared to CD in reality. 2. Dynamic range of LP is much wider than 50db? As I said, at best it's 80db. Please, understand that it is bound by law of physics. There is no way you can manipulate law of physics. There is no way LP can compete with CD for this regard unless CD is terribly mastered. 3. I lost my words there. ALL machines have thing called "error". Errors are introduced in EVERY stage of the analog lines because they are all mechanical parts. Digital also have error being introduced, but the number of incidents are FAR FEWER. |
