Speakers small enough for desktop use

Want to begin at the beginning in assembling a stereo system to use around a computer source in a desktop environment in a smaller room. Looking for ideas on what people have found from experience to work well in this situation with the following criteria:

Up to $1K budget (for the speakers that is)
Coherent in the nearfield
Magnetically shielded
Reasonably easy to drive
Decent sonics at lower volumes but able to go somewhat loud
Not overly critical regarding listening angle
OK near wall behind
Don't require a "subwoofer" to sound pleasing (obviously deep bass will be absent and that's fine as long as the speakers are balanced correctly for use alone)
Portable for use in different situations (no in- or on-wall solutions)

I'm not against considering self-powered speakers (at a higher budget if needed), but for now am assuming I'll get some sort of small amp (however probably not flea-powered tubes, more likely a SS switching amp). Pro monitors marketed for recording studio desktop use OK as long as they're intended to be fuller-range and flatter than not. I'm also not decided whether these will be placed directly on the desktop or above it on some sort of stand or wall mounting. Thanks and remember to keep 'em small!
