there you got it bro...you answered your own question...

still don't get it...dont test ur sound system with ur self compiled cd...

go out and buy an original cd...those cds are mastered properly....

if you listen to chinese song, get the old Jacky Cheung circa early 90s late 80s original cds...

if you wanna try bass...try going to those shop that joins IASCA sound competition and try to ask them to borrow you their SPL cds..no need what music what sound or send what song over...no point to test cuz we can never ever burn a cd as clear as a mastered cd
