A recent poll conducted to determine why many have refused to embrace
digital recording, it was revealed that most respondents think that even the
current state of art digital converters are incapable of accurately
capturing all available audible information.

While all respondents agreed that the debate people are currently having on
the validity of 192kHz sampling rates is ridiculous and that anything less
than a 384kHz sampling rate is unacceptable, the respondents were sharply
divided when it came to even higher sampling rates. 52% felt that 384kHz was
sufficient, 37% felt that 768kHz would be significantly better and 11% felt
that 1.536MHz ( or higher ) would be required to capture everything audible
with perfect accuracy.

While such technology currently doesn't exist, or at least is extremely
difficult and/or expensive to obtain, many feel that consumer and marketing
demands will turn this around in the next few years.
