There are many statements in this piece that I take issue with.First, your preference for LPs. Numerous tests, to which you do not allude, have shown that frequency response beyond 20khz is not audible, and that, in double blind testing, few, if any people, can discern any "difference" between audio sources whose only difference is response above 20khz. More depressingly, after about age 30, males' ability to hear cuts off around 16khz, not 20. (Women generally are more sensitive to high frequencies than men, but still can't detect anything above 20khz under the best of conditions.) It is pretty much undisputed that CDs contain far more information than LPs. People didn't switch to CDs just because they were more convenient - they switched because they sounded better and were more revealing. When digital signal processing is correctly employed, as it is by Theta Digital, for example, there's no contest. Digital blows LPs away.
I also do not agree with your appraisal ...
