Does Every Track Sound Great on Your System?

Not the best sounding SACD, but not bad and I like it on my system.

This is why I think that after you've put together a quality system, it then all comes down to the quality of the recording and its mastering. At this point, I'm buying good stuff, such as Mofi SACDs, AW XRCD24s, BN 85s, and AP SACDs. It makes a world of difference in the listening experience.

Have many old CDs. Thrash.  Production in early -late 80’s, depended on the man behind the mixing board, the producer, etc etc.  

a lot sound like banging a metal spoon on a trash lid. 
I run through audiolab 3.0 add low end, some thicker mids,   It’s fine either way. 
 

yes some sound amazing, some sound like Mercyful fate will demo tape. 
 

Well there are a couple ways to design and calibrate a system to achieve the sound you want. Sure there are some people who just want everything to sound great and enjoy the music, which is fine just understand you should not ever evaluate recordings and system components as your system is not tuned to hear music how it really sounds. A system that is tuned more faithfully to music should allow you to hear all the subtle differences in recordings. The greater the differences in bass midrange and treble is absolutely a more honest and faithful reproduction of music. There are vast differences in recordings and should hear that if you’re wanting to evaluate recordings and equipment.
