Requesting opinions on room treatment

[alkizz]

Hi All,

I'm looking to lightly treat my 2 channel listening area. Please see the picture for an idea about the layout but the basics are that it's a fairly large area that is oddly shaped. Opinions welcomed and appreciated!! Thank you

In the picture the red "star" shapes to the left and right of the speakers are planned to be diffusers. the red hexagon shapes behind the speakers are planned bass traps.

The orange shapes are couches and the arrows show the most common listening position. black are speakers, green are amps.

I have a smidge of comb filtering and echo.. it's not bad but the sound sometimes seems unbalanced and this is the reason for looking at room treatment to bring it into balance

System components:
TT - VPI Prime Signature
Preamp - McIntosh C1100
Amps - McIntosh MC2301's
Speakers - Wilson Audio Sabrina's
Cables - Transparent Super (balanced)

side note - I live in FL and the walls are CBS on the outside. Attic is treated with spray foam (open cell).
