Sheffield Lab
The Audiophile Reference Series
Sheffields`s 20+->16 Ultra Matrix Processing is a mastering technique that extracts more information from our analog or 20 bit digital tapes, to be encoded and transferred to the CD master. The process "folds down" 20 bits of digital information onto the 16 bit CD medium using Sheffield`s own 20 bit converter and an Apogee UV22 processor. This combination creates the truest, most accurate CD master from the original analog or 20 bit digital source recording.
