Hi
It seems a lot of people have the Tannoy Mercury F1 Custom paired with this wonderful Micro system and they do sound great. However, I have recently connected a pair of Wharfedale 9.1 diamonds, that I had spare, and I think these are an improvement especially in the mid-range. Both of these wonderful little speaker should be witnin in your budget and if you shop wisely you might be able to pick up a pair of Soundstyle Z11 speaker stands to mount them on!
