Lots to choose from in that price range but simple advice is listen to them before buying. I recently auditioned lots and ended up going for Audiophysics ,I just felt they were detailed and relatively neutral but then one persons neuttal is anothers cold or coloured.They are relatively easily driven as well. Others are Neat and Proac but there are many to choose from.
Yup... could easily find some second hand Audio Physics.
