I was looking at some discs at Chesky's site and they have a couple of free downloads from the Area 31 disc
http://www.chesky.com/core/details.cfm?productcode=SACD288 . This disc is in David's personal top 10 list. One of the tracks available for free is "The Girl from Guatamala". He says,
"
Now let's listen to Track 4, "The Girl From Guatemala." This is my all-time reference for a female vocal. The soprano is about 10 feet behind the mike. You hear her delicate voice right in the center of the orchestra. This track is a great speaker crossover test as her voice should be seamless from the low to the high ranges. Here, should be a sense of coherency to the voice from octave to octave. There should not be any suck-outs or brightness in the frequency range."
These tracks won't give the sound of the disc but they are still pretty darn amazing!
