New high resolution SACD releases, players and technology.

"The SACD medium was/is a series of compromises to get multichannel audio onto a disc in a secure format."

Are you able to post more info?

PS - if it's simply 64fs vs 128fs, i think when DSD was "invented" 64fs was the norm for sigma delta ADCs.

Of course, the "ideal" no-compromise format would be the "native" sigma delta modulation of the ADC with no decimation, but the bandwidth requirements for that will be very high (5 bits at 128fs = 28.2Mbits/s - 1 hour would require 12.7Gbytes of storage)
