New speaker placement

Without a view of the side walls, back walls, and some indication of where your sweet seat is located its kinda tough, but assuming your listening chair and speakers are triangulated, close to equalaterally, and stereo imaging, especially depth of image, is important to you , I'd probably want to get the speakers a bit further out into the room, have something to cover the TV when listening critically to 2 channel stereo such as a blanket, lap robe etc, and I'd want to hae some deadening or diffusive materiel on the wall behind the listener.

If you don't have specific frequency problem you need to deal with, most domestically approved things will be sufficient to maintain good sound. Think bookcases, wall hangings, large plants, etc located in strategic places.

Nice stuff......Love the tubes.

I'd agree with the previous posters on having some treatments on the front and back wall. From the pictures of your system, it seems like your speakers are quite far from the side walls. If that's the case, treatments on side walls may not be too necessary. I would think the biggest impact would be the front wall and placement of speakers. Your TV at the middle isn't helping too much and I would concur with Newbee's idea. It depends on whether you would be willing to sacrifice aesthetics by placing some absorption panels behind the speakers and/or TV. As for the back wall, you can experiment with either diffusion(tall CD racks or book racks will do) or absorption.

Thanks for all the informative replies thus far
I have added a sketch of my room setup including proposed treatments.

The sketch is done to scale
The drawing has been re worked more then once disregard the old speaker placement and areas shaded in grey

No one can tell you where to place you speakers by looking at a picture or drawing of your room. It's a waste of time and effort.

Seriously consider a Sumiko speaker set. See this thread for more insight:
