Just went to training on the new Helo system from Denon. They may have actually come up with a winner. Phone / tablet GUI looks better than the old Sonos Gui ( new Sonos GUI is a joke. ) Being released with 2 way modules for Crestron, URC, Savant and RTI. Hardware is very similar to what Sonos has but will add an all in one multi zone chassis around CEDIA and may be built into newer Deneon receivers soon.
