Dazzdax,
You have good stuff so its surprising to me.
I'm assuming your CD is working properly as designed.
First I'd like to know more about the rest of your system: amp, speakers, ICs, etc.
I think a common problem with CD playback is that often the amp or pre-amp cannot handle the dynamics, both large scale and micro, as well with digital sources as they can with phono analog sources. The result may be an uninvolving or less interesting sound.
Or if the dynamics including fine detail sounds pretty good but the tonal balance is off, perhaps a different DAC might offer a solution.
