The Jeeves stories, Detroit Ragtime and The Big Blue triedunture read and wrote are simply wonderful. I tell you, as I have already told her, her voice is amazing!
It´s so often the materiality of the voice that attracts and fascinates me most when listening to audiobooks or podfics - having said said that, jadesfire2808´s voice is very pleasing to the ear, too.
But actually it´s kind of impossible to pick the "best". There are simply too much good stuff.
