Helloooooooooo

I'm on my bachelors party in amsterdam from 11th to 15th January 2008 with my friends.
This will be my third trip (pun intended) there in 6 months )))))
My friends have never been there though.

Can someone please let me know good clubs/pubs/lounges/coffeeshops where i can hear some:

1. DnB - sickness. totally hooked on it lately.
2. Trance (a&b, avb, pvd the likes)

Thanks in advance.
Also, giving me some ideas for the partying for 4 nights straight is always helpful.

cheers.
