Am I getting Hi Res Music

[PES]

Evening All! Just bought my first 96/24 file - from HDTracks website (Eric Clapton & Friends - The Breeze). Most of Clapton's albums are well recorded/produced so I wondered how much better a 96/24 file would be compared to the CD format? Currently my music library is all AIFF CD rips stored on an iMac using the latest version of iTunes. Question; I cannot tell much difference playing this 96/24 file selecting in Dev AIR 2.1.2 the format 24 bits/96000 Hz or the CD default of 16 bits / 44000 Hz so it's another quality recording but what's the real point of this manual function of selecting bits/Hz?
