IMO the Hecos have a high PRAT factor whereas the Elacs are more refined so whatever floats your boat. I love them both. A lot of people would be perfectly happy with the PM1s but overall my vote goes to the Elac BS203 Anniversary.
What was interesting is just how well the Myryad Mi worked with all the speakers. I'd been meaning to try one for some time and so glad I did. If you are looking for an all in one system its a gem.
