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.0 BACKGROUND
Since the standardization of the 16-bit/44.1-kHz CD
pulse-code modulation format, over 25 years ago, its quality
as a recording medium has been the target of regular
criticism, both in the subjective audio press and among
audio professionals. The complaints typically focus on a
perceived harshness, lack of depth, and/or a cold, sterile
sound. However, blind comparisons of CDs against their
source tapes have revealed these perceptions to be unfounded.
To that extent, the CD standard was transparent,
whether the original source was digital or analog.
Meanwhile digital technologies evolved, and in the past
several years two new high-resolution audio technologies,
Super Audio CD (SACD) and DVD-Audio, have emerged
as alternatives.
The usefulness of the increased dynamic range afforded
by longer word lengths for mixdown has never been in
question. Both new systems moreover carry multiple channels,
clearly a potential advantage for home playback. But
these acknowledged capabilities aside, each of the highresolution
audio technologies

Чушь полная. Я Вас спрашивал ранее - Вы сами лично сравнивали? Наверное нет! Зачем тогда доказывать то, то пишут "на заборе". Или остальные такие идиоты и специально покупают SACD диски?
