The upside is that you get very realistic sound with harmonics produced above the 20Khz brickwall inherant with RIAA CD Audio 16 Bit, 44Khz spec.
The human ear can't hear frequencies higher than 20KHz. If the sample rate is high enough to accommodate frequencies up to 20KHz, then wouldn't a higher sample rate be redundant?
Not really. Harmonic distortion and comb filtering in the ultrasonic ranges can affect sound at frequencies in the audible range do to beat frequency. A lot of high end mixing consoles have a frequency response range from 0Hz to 100Khz, and a lot of the phase interaction in the ultrasonic range is partly responsible for giving gear like Neve, SSL, API, etc. their sound.
Conversely, Current industry standard Digital Audio recording is recorded at 24 and 32 bit resolution with sample rate of either 96Khz or 192Khz which not only provides for a much clearer recording, and makes edits much finer, but also captures the exact sonic signature of the gear used due to the fact that frequencies above 20Khz are not brickwalled out of existance.
Listen to an original, unremastered digital recording from the 1980's (Which was recorded at RIAA standard 16 BR/44K SR) and compare the sound quality with almost anything professionally recorded within the past few years, and you will hear a BIG differance in audio quality.
