Hi v1c,
Thanks for the information, I am struggling to think of a player that would better my Denon 2500BT for PQ and SQ, the "slow" load times do not bother me and so far all the discs I have play.
As for the 85, this is a stunning receiver and is certainly a move up from the 72 (although that was a good amp), it makes the Apex perform very well giving an open and detailed sound.
The only gripe I have is the menu system for the HMG when streaming music, it has not been improved on since the 72.
I use my Sonos for streaming and the iPad app (excellent), I did want to stream higher res files to the 85 but the Sonos is limited.
I hope the glitches are sorted out soon for your 55.
