Surely this is only at twice the audible frequency ? We cannot physically hear 44KHz sound but we sample at that rate because its the nyquist value of 22KHz which is the upper bound of our frequency range ? Assuming that (as previously mentioned) the frequency response of vinyl will not provide a constant gain across the entire spectrum then it seems reasonable to assume that a digital source of sufficient sampling rate can replicate vinyl with no audible difference ?? ------------------------------------------------------------------------------ This message is intended only for the personal and confidential use of the designated recipient(s) named above.
