Is my room doomed? Pic

mbl has some smaller monitors that are largely omni and sit on stands that I could envision being a nice fit to a room like that. Mirage may also for much lower cost.

Monitors on stands would help keep the floors out of the equation. The more wide dispersion or omni the monitors, are the better.

Floor standing OHMs would be a possibility as well. A smaller pair might work well in that room. These are bottom ported though so you would have to be careful about not going overboard with the bass as they interact with what appears to be lively wood floors.

I would say it's 70% room / 30% set up. The room is a wide open space with little boundary reinforcement, it may be better suited to an omnidirectional radiator. The back wall (being a hard flat surface) won't help any with the soundstage. Actually, every surface being hard and flat isn't helping. Lastly, I think your seating position may be too close to the back wall.

I really wanted to post to say that if you laid out this kind of money at one dealer, they had better get over to your place and help you find a position you are happy with. It's one thing for a dealer to sell you a $1000 pair of speakers and say "have fun"; but when you buy a precision instrument like this system, the dealer has a responsibility to make sure it is performing to your expectations.

I agree with that!

Beautiful room and system, congratulations. If it were mine, I would try a couple of the Diffuser panels from Acoustic Revive . They are more versatile than many of the room tx's and do many things depending on where you place them. I would try them on the sides, behind and also on the backwall and see how each position effected the sound. It could give you an idea of where the issue is too. They can stand on their own or be hung and are not too out of line with your decor. Furutech also makes some.

Maybe I missed it but were the cables and power treatments the same in the dealer's system?

I would guess the side firing woofers and lack of side walls is the major part of the problem. Wrong room or wrong speakers, take your pick. An omni like MBL or Duevel would certainly be an option. In that space, you could also do a large planar like the Magnepan 20.1 or high quality stand mount 2 ways and a pair of subs like the Wilson Benesch Torus. You have a beautiful living area.
