OP, please do not feel self conscious about the state of your room. Most of us constantly have rooms in a state of flux.
The photo is incredibly revealing… sonically. First, move the PC away from the integrated. PCs are really noisy and you can pick up all sorts of it being that close.
Second, the speaker positions look really compromised. With that much bare wall… and the speakers that close to the wall you are likely reinforcing the treble and probably compromising the bass. The window may not be helpful as well.
Before buying anything I would start working with what you have. The thing that is immediately obvious is the setup is a big problem. Do you have options? Do you have a location where you could build a six foot triangle between your speakers an your sitting location with space behind and on sides? Could you have one side of the room for your workstation and the other your system?
Even if not permanent, I would try to build your system in the triangle… without walls so close behind and sides… then dampen the back and side walls where reflections. Then toe in on the speakers. See what it is capable of.
