Biggest Sound in the Littliest Box

Revel M20 is the best sound I've heard from a monitor. Definitely on my wish list, without a doubt!

B&W Signature 805.

Check out the ProAc reference 8 sig. This mini monitor can produce big soundstage if driven by the right power amp. Power required should be around 100W but it depends on the size of your listening room. Good luck.

Thank you everyone for your inputs. There are some very good suggestions. I guess I should have made my question a little clearer. My current speakers are the Dynaudio 3.3. I want to stay with about the same size but I am looking for bigger sound, like the one you can find from speakers like Wilson Slam, Nearfield Acoustics, Wisdom Audio, and etc. Is this achievable or the law of physical doesn't allow for such things. You can suspect that I like to listen to my music loud.

Spendors are legendary for having a vast,open, soundstage...they really do have a deep, spacious quality to them...maybe not the best for extremely loud listening...but I would opt for accuracy and transparency over volume...they are one of the few box speakers that can compete with planars and stats...and they dont sound thin in the midrange....
