On amazon.co.uk, it list a few Queen releases on SHM CDs.
Now whislt I am intending to buy the remasters at first, I'll like to know some infomation on what SHM CDs are.
Do note this discusussion is not for the quailty of the rereleases (i.e compression, loudness wars etc) as quaility is opinions and everyone knows opinions vary.
From CD Japan website
"The high quality SHM-CD (Super High Material CD) format features enhanced audio quality through the use of a special polycarbonate plastic. SHM-CDs feature improved transparency on the data side of the disc, allowing for more accurate reading of CD data by the CD player laser head. SHM-CD format CDs are fully compatible with standard CD players"
