Room Response

I have taken years and a lot of experimentation in trying to make my listening room, as good as I can. I have incorporated absorption and am currently making a quadratic diffuser for my front wall. Even though I've done or doing these things, my room isn't perfectly balanced, as far as it's layout. It's a basic triangle 19'x21'x9'. I'm concerned that my TT rack on one side, my end table on the other etc, is disrupting my sound. My listening "triangle" is pristine, but know all room contents has an effect. In your experiences, how has your room floor standing contents, etc, effected your sound? Im mindful about diffusion and absorption.  I find I may have to adjust my balance control, depending on the CD, or LP. I experience this on a regular basis. I think this is normal though. I may be TOO analytical. I have gone from a 3 seater couch, to single listening chair,which has had more of an effect than I thought. Guests have to take turns in the sweet spot. Couldn't occupy thee same spot anyway.  Unless she's my wife:).

I also have a single listening chair (a wood rocker) and I sit fairly close to my Quad ESL's. When I rock in the chair, it affects the listening experience so I've learned to sit still. I was anal retentive about getting the angle on my speakers correct. Also, I have thick wool military blankets on my wood floors and acoustic foam along the sloping side walls. Fortunately, I don't have appliances in my attic listening room with the exception of a window unit air conditioner which remains turned off while listening. I'm finally happy with the sound coming from my stereo but it took some time for me to get there.

@handymann - the best treatments I have applied have been at the upper "layer" of the room...
In my old 12 x 15 x 8 room
1.  I had an 8ft wide vinly blind behind the listening position - it was only lowered about 15 inches - any lower made no difference
2. I had a sound absorbing panel on top of a book shelf to the right of the listening position - it improved clarity a lot - guess it stopped reflections between the top of the bookshelf and the ceiling
3. the floor was hardwood with a 5 x 8ft rug

In my new room I only have the panel on top of the bookshelf.

The new room is 16.5 x 40 x 8 ft with dropped sections taking it down to 7 ft
- the speaker are 8 ft from the wall behind them and 4.5 ft in from the sides
- there is around 24 ft of open space behind the listening position

The entire room is carpeted

I no longer hear any reflections

The image is huge and 3D.

I have also applied the vinyl blind treatment at a friends concrete condo with 11 ft ceilings - the improvements were very dramatic.

I would focus effort on curbing reflections in the upper level of the room
