Missing and/or greatly recessed sound

I have an issue with my turntable setup that I'm trying to solve.  Have thought the overall sound was "missing" something but could never put my finger on it to the other night.  In listening to Neil Young's Remastered LP Decade - Southern Man, the lead guitar is so recessed (you have to really listen for it), if you weren't familiar with the song, you would think it wasn't part of the song.  The vocals, cymbals, piano, bass, drums, kick drum are all clear and present, both channels working (both through headphones and loudspeakers) but the lead guitar basically gone.

On another cut, Cowgirl in the Sand, the lead guitar cut is clear and prominent, but the rhythm guitar is greatly recessed and hard to hear.  Again, vocals, bass, drums, kick drum are all there, just extremely hard to hear the rhythm guitar.

Equipment is:
Thorens TD-150
Sumiko head shell & arm
Denon 103R
Sutherland Insight Phono Preamp
Emotiva XMC-1
Emotiva Amps
Goldenear Triton's 2

Have checked Insight settings, cabling, head shell connections, etc., but looking at suggestions on what to look for to solve.

Thanks in advance!
