I already own 14 of these SHM-CDs and they all sound fantastic.
This is not a gimmick or another rip off. They say that they are using 1994 remastering , but , they are using the 2003 / 2005 warner / japan paper sleeves versions , as their base.
This is now the best sound for CDs out there. As good as , SACD , HDCD and / or MOFI.
