Speaker Width?

That cabinet is killing any chance of good imaging and soundstaging. 
Start by using the Herbies Gliders and move the speakers away from the side wall and closer to the console. Then pull the speaks forward with possible toe-in.

Your TT may need to be moved due to acoustic reverberation from the speaker cabinet. 

This is experimentation, it may not be your final positioning.

You won't beat those Isoacoustic Gaia's, certainly not with Herbies sliders. The Herbies provide flexibility for positioning but the Gaia are superior for sonics.

Is that a bong??
