First, while reading your response i'm listening to Norah Jones (sunrise - live itunes festival) she is the best! With that tid bit aside, I can say I do believe that yamie's Ai is a marketing thing designed to help those who are not familiar with DSP. Yamaha does not seem to delete old DSP choices. You have so many choices with a yamie. After listening, I would not be surprised if it's not just going back and forth from the latest Dolby to DTS.

Lots of speakers from many
manufactures...mostly Axiom
