I don't have sibilance problems, are my speakers dull?

Another poster asked for help dealing with sibilant performances.

It got me to thinking, the one thing I have not had a problem with in like forever is sibilance. Maybe this is because I don’t seek to make my system "revealing" which to me often just means bright.

I’m now kind of curious, exactly what kind of gear and recordings bring this problem out?

Best,

E
