It *CAN* be. Depending on the program material at lower levels it is VERY noticeable with 16 bit recordings. There is simply not enough resolution in 16/44.1 to capture delicate nuances near the noise floor. Going to 24bit improves resolution dramatically (remember 16 bit = 65,536 discrete voltage levels per sample; 24 bit = 16,777,216 discrete voltage levels per signal!).
96,000 samples/second does lift upper range to 48kHz (theoretical) so that is standard as magnetic analog recording in the studio can go to 40k. What good is it if people can hear to 20k (with outstanding hearing I have to say)? Well plenty as it ensures much more accurate reproduction of the highs in the upper limits of what one can hear.
Some CD's just sound plain bad - even in the past which were great analog recordings. This was due to limited converters of the time. ADC's have improved substantially in the past 20 years. This is why if one has access to original mastertapes a very good transfer (even if cut to 16/44.1) is possible!
Keep in mind that modern compressed releases will never show the limits of 16/44.1 as their dynamic range is so compressed. :| At that point, 128kbps MP3 might as well be considered CD quality with such program material. :Q Some of the electronic popjunk has samples of similar quality and their artifacts can be readily heard. (that is if you can stand some of the atypical pop singer voices shrilling alongside of them.
