K2HD/24bit cds from Japan

Has anyone compared or tried these new offerings fromm Japan the 100KHz / 24bit Limited Numbered Japan K2HD CD's. I see some interesting titles including the old Mercury
Hi-Fi a la Espanola and Popovers..anyone thanks
I have a couple and these are very good....also I am buying the mentioned SHM discs too. Very much as SACD sound and even better.....
i have shm and k2hd cds.

there is no generalizing as to sound.

some k2hd tracks are preferable to red book others not. i am not a fan of shm.

i am hoping that blue ray audio will provide excellent sound quality.

the main issue is the recording, not the format.

for example, there are some 16 bit cds preferable to sacd discs.
