Hello,
I have listened to the to Micro and own the Mini Utopia. The Micro is an excellent speaker but the Mini has a larger cabinet and the base response is better and they have a "bigger" sound. It you want a lot of base you will need a subwoofer. I had Kef 107's before the Mini's and will probably end up with a sub, but I am not missing it as much as I thought I might. I am using Mcintosh solid state gear and the speakers sound great. A tube pre amp would be preferable (my next upgrade) and a tube or solid state amp would work very well. I have also listened to the Utopia with CJ, Sim Audio and Plinus electronics. My preference is in that respective order.
