I know what you mean Tpreaves, and I can't say I disagree with you because I just got my system and just starting to break the speakers in. I'm still waiting for my cables to arrive and I don't even have a decent source (just testing it out with a sony dvd player, but I'm waiting for the Sony CE595 to arrive since it was cheap and want to see what difference SACD makes). However I played the Slayer Reign in Blood album, recorded in the 80s so I doubt it would be qualified as "high quality". I was just amazed at the clarity of the drums and guitars. There's parts of songs where only the drums or only the guitar are playing, and those parts are great. However, when they all start playing it gets messy. I was hoping that a quality CD player or DAC would help to bring more air between the instruments to get more separation and depth.
I consider the recordings of the band Tool to be of really good quality (especially the last 2 albums), and I notice the same issues with those albums.
