Harbeth P3ESR vs Fritz Rev 5 vs DeVore Gibbon 3XL

Ok, here's the deal.....

I'd like to assemble a secondary two channel music system in my small den. It is only 11.5 ft by 11.5 ft .....so not only is it very small, but also square! Also, because the room is so small, the speakers will have to be placed quite close to the wall that resides behind the back of the speaker. Yikes!

The music I'd like to listen to in this room would be vocals, violin/cello sonatas, piano, and anything acoustical in nature.

Tone and timbre are of paramount importance to me. I do not want to use a subwoofer.....hoping one would not be needed for the above listed music types.

There are no Fritz dealers, but he does allow an in home trial....very nice!
The closest DeVore dealer is several states away from me.
The closest Harbeth dealer is a 12 hour round trip car ride for me.

So, if anyone here has had any experience with the above mentioned speakers and could share any insight of how they may perform in my small and non-optimum room.....it would be greatly appreciated.
