Has anyone run into any info as to the output specs?  Wondering if its limited ala Sonos or could possible do higher rates. In other words any idea what file formats it will support. -Is output set at CD-quality (16-bit/44.1kHz) or will it support  "hi-res" audio up to 24-bit/192kHz?

Looks like it'll go up to 24/96

They don't give much detail though

figured id add one more question: does it support and play local files (i.e. ripped cds) or just streaming services?

Anything you can cast from your phone.

Most likely you can play via anything that will run Google Chrome.
