It is possible to compare anything to anything but what is the point. The Stradis are a nice speaker but are not really competitive with most of todays' speaker systems in that price point. They really don't go low enough.
The Strads have classic SF strengths of coherence and a great midrange and are very listenable.
Where they fall down is dynamic range, deep bass response and ultimate transparency and holography.
The Sasha is a nice speaker and there are many other great speakers which compete with that speaker, if I was looking at the Sasha I would also recommend the KEF 207.2 which are outstanding if set up correctly.
