LP's vocals are hidden behind music on Stereo

[80?s VinylHead]

Hi all,

I'm a super newbie to vinyl and vintage systems. I set up up newly acquired system (Marantz 6110 TT, Pioneer KX444 amp, and pair of Akai SW135?s), on getting home I set it up in a temp place to test everything it all worked perfectly on Stereo.

Moved the system to its new home in my house and now when i play even stereo stated LP's the vocals are hidden behind the music. If i switch to mono the vocals come right out but obviously with a super lowered volume availability.

Have i done something wrong? Sorry if this is a complete newbie mistake
