https://www.ebay.com/itm/201415889369I bought new CD from Ebay from above source.
It is a really good source of music to test the sound stage of your system.
In my two channel system, soundstage extend 8 ft beyond both right and left speakers.
It almost sound 3D with 2 channel system with thunderous bass.
It use Qsound effect.
I feel as if I am inside the music.
This is a really classic.
