Wilson Audio Sasha break-in time ?

For you or the speaker? Changing speakers is tough and every record sounds different than you're used to. Give it a month for both of you. This way you'll forget what your last speakers sounded like and accept the new ones on their own merit, or lack of. What you shouldn't do is start changing cables and stuff like that to try and compensate for the differences. Good luck.

Judging from my friend Dave's experence it takes quite a while; keeps getting better for a long time. I would say a few hundred at least for best performance.

I nave been told they fully bloom around 400 hours .....

Does anybody know whether Sasha is sharp on s sounds as in spitting accentuated s sound and whether this improves with time.
