what would you do?

In my small room I put GIK Acoustics sound panels (total cost $750) and it tamed the bass and other things to now sound excellent. My speakers at the moment are small monitors. However, I believe a small floor stander will also sound good now in the room. Take a look at my virtual system for the placement of the panels.

Now if panels are not feasible for your aesthetics then something like the following preamp will solve your sound problems.

I am looking to buy the above piece if the floor stander I get into my treated room is still too big for the room. I am 100% confident that either 1 or a combination of both solutions will work for me.

@labguy If you can swing the panels (the low cost ones I have are not very attractive) they make a world of difference. Prior to the acoustic treatments, I used to try and play the Smashing Pumpkins Siamese Dream in my room and it was physically painful. After the treatments I could play that disk rather loud without issues. The sound was also cleaned up in all the best possible ways.

I was actually suggesting the Anthem STR preamp and not the integrated. However, I now see you are using an integrated.

An Anthem STR preamplifier ($3999) featuring its latest ARC Genesis room-correction software helped bring out the best from a pair of Paradigm Persona 7F speakers driven by two Anthem STR power amplifiers, and connected with Shunyata cables and its Denali power conditioner. Music was provided using an Aurender N10 music server. With the ARC Genesis room-correction software employed, bass was much more even throughout the room with very good imaging. It made the system sound like it was a much more expensive one.

Another option for around 3 grand would be to buy a stand mount and subs.

This is what I would do if I were smarter (and not buy a future floor stander)

1) Acoustic treatments (under $1K)
2) KEF LS50 passive (what I currently use, used $800+)
3) Sub woofer(s) for about $1000 each. I have no clue which ones are good for music but I know you can get good ones for this price.

This will give you really good sound. I am not doing this because I do not want to deal with subs but this a very smart way to go. 

Of all the speakers I have owned,  the $20K Revel Salon1, Thiel SCS4 monitors, and others, the KEF LS50 is my favorite on the top end (except bass). The bass is not that great but in a small room it is reinforced by the walls.
