I use both - an Audience aR2p-TO for my amp and a Haley for my source gear. I have no cons for either - they are both excellent devices. If someone put me up against the wall I *might* say the Audience provides a bit more of a sense of depth in the soundstage, but both provide a quieter, lower noise floor with no added "character" of their own. I wouldn't give up either one. YMMV.
