Wyred 4 Sound DAC owners

I too have the Femto clock which I think is a very good thing

slow = more air;  the highs just float

I have the W4S DAC.  I'd like to here more about this.

It's part of the menu options- it's there for you to try

On the W4S DSD SE, I also prefer the slow setting and feel the soundstage is more open and highs generally better.   However, with DSD the default BW setting sounds best to me after much experimentation.
