Two years or so ago there was an in interesting 'engineering report'
published in the AES journal. It reported on the results of a long
series of listening tests involving hundreds of listeners, all of 
then selected for their interest in high quality audio. 

For these tests the authors used 'audiophile' DVD-A recordings 
(mostly classical music and jazz IIRC), all of them 24-bit, 96
or or 192 kHz, and had the listeners compare them to a version
transcoded to CD standards (44.1 kHz, 16 bit). Two results 
emerged from this:

1. Nobody could hear any difference between the original recordings,
reproduced using the best equipment available, and the transcoded
versions. 

2. Almost all listeners preferred the 'audiophile' recordings to
other versions of the same music released on CD. 

The latter result is quite surprising, but given the first one it
says nothing at all about the merits of higher sample rates. It is
just the result of the 'audiophile' recordings (targeted at a very
critical niche audience) being produced with more attention to audio
and musical quality than the average CD.

There are three of them, and Alleline.
