Martin Colloms makes a few comments in his review of the Alexia in HifiCritic:
While I still love the MAXX III, the Alexia is faster, more open, clearer, better focused, more upbeat, more transparent and has more tactile bass and faster, more upbeat rhythms. However, it represents a significantly tougher load, and is not quite as powerful – though more than powerful enough to set the musical standard for size and price.
