[Engineering Report] Claims both published and anecdotal are regularly made for audibly superior sound quality for two-channel audio encoded with longer word lengths and/or at higher sampling rates than the 16-bit/44.1-kHz CD standard. The authors report on a series of double-blind tests comparing the analog output of high-resolution players playing high-resolution recordings with the same signal passed through a 16-bit/44.1-kHz “bottleneck.” The tests were conducted for over a year using different systems and a variety of subjects. The systems included expensive professional monitors and one high-end system with electrostatic loudspeakers and expensive components and cables. The subjects included professional recording engineers, students in a university recording program, and dedicated audiophiles. The test results show that the CD-quality A/D/A loop was undetectable at normal-to-loud listening levels, by any of the subjects, on any of the playback systems. The noise of the CD-quality loop was audible only at very elevated levels.

Um es auch dem klarzumachen der englisch nicht als seine zweitsprache spricht:
Teilnehmer: dem audio umfeld zugehoerend
24/96signal - d/a converter - hoerer
24/96 signal - d/a converter - a/d 16/44.1 - d/a converter - hoerer
resultat: unterschiede nur hoerbar (erhoehung des rauschpegels) bei entsprechend hoeherer lautstaerke (? db am hoerplatz?).
