Have to agree with rumadian and Jaybo.
On the Naim Front - I have never yet heard a pair of speakers that the Nait 5i integrated could not drive to comfortably loud listening levels and still make it sound like (real) music, including: Quad 21L, Devore Gibbon 8's, Totem Arros, Hawks & Forest, Epos M16 and Naim's own SL2. Note that these are all small floor standers and may be slightly more efficient than the smaller monitors you are considering. These speakers are all ass kickers by the way, just in case you are ever looking for a bit larger box.
Other random notes:
Another Dynaudio monitor that I have been impressed by is the Audience 52. This is a bigger box than the Focus 140, and sounds like it. I listened carefully to this speaker driven by a Rega P3 TT and a PrimaLuna ProLogue 2 integrated tube amp, and was QUITE IMPRESSED. The ProLogue is only rated at 40 W, but was easily able to drive the 52's. This amp might also work well with the 140's since they have the same sensitivity rating (86db). Not sure the used price for this amp is below $1000 yet, but it's worth a look.
I also demoed the Dynaudio Audience 72 floor stander with NAD separates driven by an NAD cd player, and that combination sounded very nice, although the NAD amp (C272) was packing considerably more horsepower than a the C325. Again, the little NAD will make pretty noise with either the Totem 1's or the little Dynaudio Focus, but you will just need a more capable amp to extract the total goodness therein.
