In regard to information present, and not heard clearly; I recall being at a high end emporium and requesting them to play my CD of Santana's "Abraxas". This was my CD; I bought the LP Abraxas when it came out; to say that I was familiar with the album would be an understatement; the background music that had been barely audible on all the rigs I had, was cleanly audible here. There were certain sounds that I have not heard clearly audible before nor since, and that was from a CD.
Keep in mind that this was in a "High end Emporium"; which meant that every detail in audio had been addressed; the electronics were "top of the line" Audio Research, and even the CD player was ARC. The speakers were Thiel, and the price of all that equipment was far beyond my reach, but I heard it on that day.
