You really need to go and try to hear some of your possible contenders.

I think what many of the add a sub guys are failing to notice is your speakers look to be from 1998 if this is the case of course loudspeakers from today will offer more clarity.

The issue of bass is as much of how the room is interacting as well as the capabliities of the loudspeakers.

ATC makes screaming good monitors that are very neutral and throw a huge soundstage, they are also very dyanmic with good bass, hoever they are not that efficient, and like power, they also have very tight bass but it is not subwoofer quantity.

The Dynaudio C1 are very fine monitors they only go down to 45hz and are also power hungry. 

If you are really looking for subwoofer level bass out of a small speaker, we were exhibiting at the New York Audio Show with the Legacy Cablire which is a bit more than your budget, however, they had unbelievable bass which was tight and room filling, the 8 inch woofer has 1 inch of linear throw so it can move some air and the speaker has dual passives.

If you can squeeze up to $5500 you will be blown away be their performance and they are quite compact and stunning looking they are also efficient and play loud. The Calibre is flat down to 38hz which is very impressive for a monitor.

The Calibre’s also image extremely well and use a state of the art Heil AMT tweeter mated with a fantastic Italian midrange driver.

Spenceroo, most people don't want a pair of hideous pro speakers in their Living Rooms, you mistake what sounds good and what most people want to have in their homes. 

A high performance speaker should fit nicely into someone's home and decor. 

OP you need to get yourself to some of your local dealers and or Audio shows and actually listen to some of the newer contenders in your price range.

I would put ATC, Legacy, on your list in the uber monitor range, If you really want deep bass very few speakers that are this compact hit as hard and go as low. 

The Wells amp is powerful enough to drive almost anything. 

Go forth and listen.

Stuarik,

Yes the room plays a huge variable, however, the multitude of choices that are being mentioned is mind boggoling.

For example we sell five or more brands of mini monitors, KEF, ATC, Paradigm, Athom, PSB, Legacy.

When a person comes to my shop as long as we keep the variables the same you can hear the overall personality change of the speakers and each different companies product brings something else to the table. 

In that way it makes it easier for a person to go to the next step which would be an in home demo if that is what is required.

You may love a pair of newer Dynaudio's or you may not as the newer speakers are much more transparent than yours. So unless you love trying and buying, trying and buying, etc, over and over again, going to a good dealer if there is one in your area or going to a regional show may help you find the model to take the next step with or flying  into a city with many different dealers such as New York and demoing models in your price range you will have a very hard time of this. 

Your tastes may vary as to the rest of the posters and you may love or hate whatever people are recommending, therefore the only way to know is to go and listen to as many models that make sense with your price range, matching equipment and decor that will work for you.

The path is your own, and so is your methodology and you are right that different stores are going to produce different results the idea is to try to gain a perspective as to the overall qualities of a brand as a starting point.
