The Airplay software on the Pioneer crashes a lot. When it doesn't crash, it plays music out of sync with other Apple airplay devices.
The HMG server? Who let that ship? Did they look up from their Atari 2600 for more then a few seconds before saying "Menus! What sort of crazy new concepts for an interface will you think of next? Ship it!"
Their support for their iPad and iPhone application has been non-existant.
On the other hand, the Pioneer sounds better then my 20 year old Onkyo amp (I think).
Someday, someone, is going to build a modern amplifier right.
I really doubt it will be Pioneer.
