Thanks to a lot of folks here, I have learned how to distinguish the Hoffman and Nichols versions of Steely Dan Aja (CD). For Aja, there are many ways to distinguish the Hoffman version relative to the Nichols version (both pressed in Japan). Unfortunately, I am not clear on how to distinguish the Hoffman versus Nichols versions of Katy Lied. All I know is that the Hoffman version of Katy Lied has "MCAD 37043 S1E:1" as the matrix code (stamped in the inner ring of the CD). Is this the only identifying mark? Below is a list of differences between the Hoffman and Nichols versions of Aja. Are such differences noted for Katy Lied too? * Hoffman version has "CSR COMPACT DISC" repeating in the plastic inner ring. Nichols version does not. * For Hoffman version, each song starts at 0:00. For Nichols version, each song starts at 0:01. * Original smooth-edge jewel case for Hoffman version has "Patent pending" embossed on the back. The smooth-edge jewel case for the Nichols version does not. I am looking for ways other than sound to distinguish the Hoffman and Nichols versions of Katy Lied. For one thing, sound quality is subjective. Secondly, some have said that the Hoffman and Nichols discs sound quite similar. So, I am looking for obvious ways to distinguish the discs (things to look for on the discs, songs starting at 0:00 versus 0:01, etc.). On a final note, can someone explain where the static in "Bad Sneakers" occurs? I read once that the static is absent on the Hoffman version but is audible on the Nichols version. Is this true? Thanks in advance for your help.
