1st question people are going to ask is what's your budget and the 2nd should be do you want to upgrade the amp at a later stage and if so what will the budget for that be?
You could go for something like Elac B5.2's or Dali Spektor 2's both of which are great speakers for their price and would work well if you did upgrade the amp at a later stage, my personal prefernce between the 2 is the Elac's and they have some of the original 5's which some argue are better on e-bay at the moment.
Wharfedale 9.1's are more budget and I have those in a desktop situation and have no plans to change them anytime soon but I'm not sure how they'd compare to the ones you already have.
