Stereo Separation - Turntable

I'm new to turntables - just bought my first Music Hall MMF2.2. I've noticed on multiple stereo vinyl recordings (recordings I am quite familiar with on CD), that the stereo separation is rather extreme. What I mean by that is on albums like Cannonball Adderley's Somethin' Else, where there is percussion and horns, the left channel plays the horns and the right channel the bass and drums. Piano is in the center. Is this typical? I thought perhaps it was a speaker placement/toeing issue, but the same setup but played on CD does not have that problem -- the sound on CD is centered with a wide sound stage.

I suppose I'm wondering if this is a limitation of my turntable, or a setup/connection issue or a recording issue? The records that I've noticed this on are all stereo and all bought new. Turntable setup includes the MMF 2.2 mentioned above, stock musichall tracker cartridge, a Cambridge Audio 640p phono stage, hooked up to an Adcom GTP500 preamp and NAD320BEE amp.

Thank you for any help/suggestions.
