o.k anybody know anything about shm-cd they claim there indistinguishable from the master?

Just picked up Santana's 'Africa Speaks' on SHM-CD...now keeping my eyes open for other titles I might enjoy...SUPERB!!!

Too funny. Most people complain that the “Breakfast in America” SHM SACD is too dull, not too bright.....

My system is quite resolving and SHM, Blu Spec CD2, XRCD, Ultra HD CD, UHQCD, and MFSL all sound better than the original versions. My only limitation in sharing my experience is that I'm not an EE guy, nor do I know the physics of how laser lights read bits of information, so I can't comment on why it's impossible that they would sound better.

@tweaknkeep, read my post above.  Different source, different mastering.
