I have some Sheffield Labs Cd's and the recordings are wonderful and uncompressed and life like. Some of the most natural and life like CD recordings I own.
Lets see I have the following CD's:
Lincoln Mayorga & Amanda Mcbroom - Growing up in Hollywood Town.
Lincoln Mayorga & Amanda Mcbroom - West of Oz.
Kodo Heartbeat Drummers of Japan.
Sheffield Drive - The Audiofile Reference Series
Michael Newman - Guitar Pleasures.
Margie Gibson - Say it with Music - Songs of Irving Berlin with Lincoln Mayorga at the piano.
Got to listen to Clair Marlo on Sheffield, Unbelievable vocals. I also have Pat Coil, James Howard Newton, Michael Harrison, Dave Grusin and Prime Cuts all sound great and very detailed
