The events related in that article and their effects on sound quality of most CDs produced since the early to mid 90's compared to before as related is consistent with what I have observed in practice, FWIW.
Most CDs since the early to mid 90's sound pretty good, though few if any are perfect still, as is typically the case. The exception is newer "loudness war" type CDs where waveforms are clipped in the interest of a "louder" sound, usually for pop/rock type CDs. But there are many others that are done quite well and are quite competitive with better vinyl done well also IMHO.
