Hi AVEX,
We are both from the east (Shanghai)so I guess I must reply your post.
I've been owning D2 for 2 years now, among other speakers.
D2 is, in general , very balanced sounding with a touch towards warm side.
Before D2, I used to own Proac TRS and the treble to me is a little bright.
However, if your room is small or they are placed at the corners, the bass can become booming, despite being front ported.
In my small AV room (3.5x 4 meters), the relax holes have to be blocked to prevent booming.
I auditioned D2 with NAIM XS integrated in a dealer's room and they sounded very good,especially the sound stage.
Although for Chinese audiophiles, it's believed that PROAC goes best with high quality tube amps.
Finally, I don't mean to be demoralizing, but Proac D2 and other gears you short-listed (Creek evo, Naim xs etc)are hardly "high -end", not in this part of the world at least. :twisted:
Have fun!!
