Hi Contour,
I posted a bit aobut the speakers in anthoer thread about Dynaudio by Solid Statesman.
I had some Contour 3.3s in my living room earlier this year. They were about 4 feet tall, 44kgs each, and the bass that came out of them made my organs vibrate and induse nausea lol. So the 1.8s are a bit more subtle. I think they are more suitable for my room also,given their size. There is some slight boom, but I like bass, and in the main it is well controlled bass.
As for partnering them with the Primare, it is just a temporary measure until my amp is fixed. The A30.1 does a decent job of driving them, although I would say it is not the ideal partner. The 1.8s and indeed probably all Dynaudios need a lot of grip and like being driven hard. The A30.1 seems a bit soft; it needs a little kick, or 'bite' to really get things going. A lot of tracks seem ever so slightly slower with the Primare. Its a lovely listen though. However the Bel Canto does it so much better, for me.
