AVR Took A Dirt Nap - Looking To Upgrade

Yesterday during a new tv install I discovered the Denon AVR would not power up. It was time for replacing, so moving on. 

I have a 5.1 set-up (center channel, Hales Design T-5 towers with a sensitivity rating around 88 or 89 db, two 15" subwoofers and two surrounds). I'm looking for all the latest software, like Dolby ATMOS etc. and an increase in watt/channel to more effectively drive my Hales Design, which are not that efficient. I'm thinking a minimum of 110W per channel. It will be used to watch movies and play music, so musicality is very important. My budget is $4 - 6K.

Initially I'm looking at Anthem, Arcam and Rotel, but I'm wide open to make & model suggestions in the above price range. It should be noted I don't want to go down the separates path.

Thank you in advance.
