Was I wrong. My problem doesn't exist. I played the CD on my two other systems and it sounds exactly the same on all three. Seems this recording, and especially the first track, accents stick clicking/tapping sound on cymbals above the cymbal sound in the left and accents the cymbal sound above the stick tapping sound in the right. I haven't heard such a pronounced difference before. Going forward, when I think there is a problem, I will make it standard practice to use all three systems to aid diagnosis. Sorry for all the unecessary posts.
