Reminds me of this posted by Penguin:The theorethical information content of vinyl is determined by the the highest possible reproducible frequence and the highest possible SN. The highest possible frequecy reproducible is detemined by the minimum radius of the needle and the rotational speed of vinyl. Practical limits exist somewhere around 50-60Khz (remember CD4 records that had a 40Khz carrier signal?) The SN is somwhere around 70-80 dB but it is frequency dependent. The SN determines the number of bits needed to reproduce the signal. Theorethically an LP contains the same amount of information as a digital signal sampled at 120Khz with 13 to 15 bits of resolution. Now would you be able to tell the difference between the analog sound and the digital sound that was sampled around the theorethical numbers? I bet you would, but it puts in perspective the minumum requireemnts to reproduce a signal with a certain SN and HF.
