I own Ayre K5xeMP and owned Dynaudios (Focus 140) before. I wouldn't call Ayre dark, or Dyanudios lively. In my experience, Ayre is dead quiet, noise free if you will, very open and transparent, and believe it or not, it's a bit sweet, I certainly enjoy it more than my previous tube preamp. It's super detailed, tight on the low end...sweet on the high end. I am very impressed by Ayre.
As for Dynaudios, Focus series was dark and boxed in, needed very high current and high volumes to open up. Once opened up, very nice sound. I like Dyns, they have a sweet top end, and an engaging low mid, high bass tuned type of a signature. Recently I heard the Contour C20s while speaker shopping...and they were very, very nice. I loved their big sound.
