sorry to write this in English but my Swedish isn't too good

I really need some help on Thule and here in Belgium the Thule owners are rather limited so i will try the scandinavian approach

I own a Thule IA 150B and would like to bi-amp with a PA 150B, however, in Belgium the PA 150B is hard to get and very expensive.
What I can find is a Thule Audio Spirit Swing power amplifier. It looks the same but i don't find any information on this amplifier.
1. Is there someone who knows if I can use the Thule Audio Spirit Swing together with the IA 150 b?
2. Do you know any shops or traders who are selling Thule, and demo or second hand preferably, an can ship to Belgium?
thanks a lot
Bram
