Best bookshelf speakers under $1,000 for NAD amps?


I have a NAD C160 pre-amp, a NAD C270 amp and a NAD C521BEE CD player.

I like the warm, liquid sort of sound and listen to a wide range of music.

With very limited space, (12'x16' room) bookshelf size speakers seems appropriate, can anyone recommend a good match for the NAD amps?

Take a look at the Sound Dynamics 300ti here on the GON , for $225.00 they are a steal! You would have to spend a lot more to beat them and if you didn't care for them you could resell and make most of your money back. Their a little large for bookshelf but need to be placed on 12 in. stands for best sound. I don't know the seller but I have heard the 300ti's and was amazed at the sound.
I agree with Ltodd in his recommendation of the Paradigm Studio 20s. You may also consider the Studio 40s. I had a NAD/ Paradigm Studio 40 v.3 setup at one time. The Paradigms can tend toward a bright sound; a good match with the warm sounding NAD.
The PSBs are in the same general school of design as the Paradigms, but I prefer them for a little more smoothness, linearity, and inner detail. For stand-mounted, you could go with their Image B25, but I think you'd get a better match for the room and more bass extension with a small tower from that series such as the Image T45. It's only 36" tall and 7" wide.
