I'm a Dynaudio dealer and I personally prefer the Dyns mated with extra muscle. The 3.4 will sound just fine with the B&K, though. In my showroom I have the very similar Focus 220 mated with the Parasound Halo A51 with amazing results. The 3.4 is very close to the Focus 220. You might check into this speaker as well.
To take it up a notch or two from the Halo's and your B&K, we often pair our Dyns with Bryston amps. You would be hard pressed to find a better combination. Our reference room has the Contour S5.4 mated with a Bryston 4B_SST.....Killer!
