I have a pair of Focal Diablo Utopia Colour Evo with MC152 (150 watts) powering them, they are clean/crisp, even surprisingly punchy; and fill the room nicely.

We have to agree with YZ the speakers need to be in front of you. 

When we have had a similar room setup we find it disconcerting to have the sound source be coming from  behind the listener 

The brain wants to be organized with the body's orientation you are facing opposite the sounds direction that will be disorienting over the long term.

Your best bet placing speakers in front of you or getting a set of small speakers you can use on the desk.

@audiotroy I think you mean that you DISAGREE with me about the speakers being behind. Coming from you I take that comment with some interest since you are rather knowledgeable about audio.

From my perspective my brain is not messed up with the unobstructed sound from behind me. I am totally messed up with sound on my desk or obstructed by monitors. It sounds awful that way.

Maybe I am a freak. Rick James style.

Is a single Curved Monitor a possibility, i.e. sound not blocked by 2nd monitor on right side. Is it technically up to what you need? 34", but curved, so only 32" wide centered between the speakers?

There must be others, just a quickie find. 4K resolution models exist also.
