Actually it's from a 2007 AES conference, not the JAES, so I'm not sure it's peer reviewed...but anyway:
"Which of the Two Digital Audio Systems Best Matches the Quality of the Analog System?"
http://www.hitech-projects.com/hera/...s/aar07pu4.pdf
It appears that the formats compared to a live feed (analog) were DXD (353.8 kHz/24) and 44.1/24, both in surround, using a blind comparison protocol. Two additional listening conditions were tested : one where the A/D signal bandwith was 100 kHz (thanks to special microphone 'super-tweeters') and the other where bandwidth was limited to 20kHz. The authors say their results show that listeners 'more often than not' identify the hi-rez audio (and not the 44.1 kHz audio) as being similar in quality to the analog feed...but only when the bandwidth is limited! In other words, only the initial sampling need be done in hi-rez, the listening can (and SHOULD) be done in 'standard rez', to achieve the analog-like effect.
Their test setup and signals must be seen/read to be believed (the pdf includes photos). They're not your typical listener setup, to say the least (compare to, say, Meyer and Moran's setup for their SACD vs CD test). Also, I'm having trouble making heads or tails of their statistics.
Love to see some input from scientists and the science-minded here. It's also being discussed on HA.org
