I am convinced that most of the problems people hear w/Sashas (or other Wilson speakers) is the setup. Proper positioning, fed by good sources, with reasonable electronics fed by clean power (most critical in my opinion) tightens up the 'bloated bass', and tames the 'sibilant highs'. The 'problem' is that people don't spend the time it takes to set up what is a very transparent transducer. My 2 cents worth.
