If you like listening at low levels (volume) you'll need something that is clear and open sounding like Merline TSMs or ProAc Response 1SC. My choice would hands down be the Merlins but they also may not be available in Belgium.
Small speakers for a small room
Currently I use Linn Kan (type 4) speakers with an LFD Mistral amp.
At that time I couldn't afford the Linn Tukan speaker wich was my first choice.
My 3 options for an upgrade:
Linn Katan, Spendor S3/5se and the PMC DB1+.
I listen mainly to classical and jazz in a small room.
I like my Kans but something is telling me there is better.
