2.0 Stereo speakers on a $2000 budget?

So, what speakers have you been using?  What are you looking to improve upon or what sonic properties of speakers and music reproduction are most important to you (i.e. Micro/macro dynamics, tonality, timing, imaging/soundstaging, etc.)?  This info would help greatly in making more targeted recommendations. 

The ProAc jumps out at me right away as interesting choice.

speakers I have heard and liked with that NAD amp or close relative:

-Vandersteen 1c
Dynaudio Audience (82 and 122 both available now on Agon used)
-B&W 683 S2
-Focal Chorus 726

note these are all very different sounding speakers but had their charms with NAD power.

other intriguing suggestions mentioned in this thread that I have heard but not with your NAD amp:

-Monitor Audio Silver 8 (Full Disclosure I own some MA speakers now and like them a lot)
-PSB Imagine tower
-Magnepan MMG's plus SVS subs (very intriguing idea)

for that matter, SVS sub(s) with any synergistic stand mount speaker like B&W CM-5, Monitor Audio Silver S2, KEF LS50, Dynaudio Excite X18, others?

There are some Revel Perfoma F32's on Agon now for $2K which strikes me as a good deal, but not sure of match with your NAD amp.

A suggestion on the NAD no matter what speakers you end up with, scrap the stock metal jumpers between the Preamp "out" and power amp "in" on the back, and replace them with decent 0.5m interconnects. Might even help tame Klipsch's treble a bit.

Magnepan has their own "bass reinforcement panels" they want you to use instead of a sub

not clear if they add any freq. extension or just SPL at freq.s that their speakers already reach

Active version of  KEF LS50 called the  LS50 Wireless is coming out, it's going to be game changing.

get a pair of Audioengine's HD6 and be done with it.
