I have posted and been quiet on this thread but I think I will have a final say; I don’t believe in 24 bit 192/96/88 KHz material. Why? because we can’t hear/appreciate it. Even if Bruce says that a filter in the high frequency digital domain is going to affect the frequencies in the “audible” range, that is not true (this is the same person who told me that he made a 88 KHz and a 192 KHz version of old material because he was asked to, not because the source would have even close to that information - we are talking old tape from the 60's).
A CD with correctly applied dither have more than enough bit depth and frequency response for any human being on this earth, i.e. if you are going to buy from HDtracks (as I still do), don't’ believe that the latest music in going to be nothing but super compressed and have a bandwidth you can probably fit on an 8-track, e.g. Eric Clapton – Old Sock (Dynamic Range 7-9: seriously you need 24 bits for that???! Pathetic Eric!)
If you like buying interconnects and speaker cables for the thousands you probably will buy into all of the 24/192 bs. If you like music and understand basic math and physics, you will understand that a carefully mastered CD will sound so much better than the over-compressed crap that is being re-sold as the emperor's new cloths.
Here is an article for you (that Bruce has read twice):
