Amplifier for Dynaudio Contour 1.3 mkII: Unison?

I have Dynaudio Contour 1.3 mkII speakers connected to a Quad 33/303 amplifier. Intend to upgrade with a new integr. amplifier (price range 1000-1400 EURO/US$)
Anyone who has experience with these speakers and the Arcam DiVa A 85 and/or Unison Research Unico?
Any comments about the differences between these two?
Any comments about possible differences with the Quad combo?Which other amplifiers in this price range would drive well the Dynaudios?
