Welcome to the forum,
I would personally go with
New Denon AVR4520CI 9 2CHANNEL 3D Networking A V Receiver Airplay AVR 4520CI 883795002578 | eBay {their are authorized distributors selling on ebay so you get full warranty}.
And
Amazon.com: Sony BDP-S5100 3D Blu-ray Disc Player with Wi-Fi: Electronics , in my experience {and listening to audio systems is a hobby of mine} you can spend a million dollars on a blu ray player BUT it wont be noticeably "better' than the above sony unit...
Here is the issue I see with expensive media players... THEY CHANGE TOO FAST!!! Buy an $1100+ Blu ray player and it is going to be replaced in 2 years or in most cases less by something new and improved, or a new model with new features... So now your $1100 blu ray player is worth $50 and you are in the market for a new $1500 Red Ray player that supports HDMI 4.9'er .....
I have spent a lot of time with the McIntosh 891 Blu ray setup in our friends home where we often go and watch movies, its in a $30K system and is supposedly one of the best Blu ray players made to date and I want to say it cost him $5K, it plays the same as a ps3, and he admits to often just using his ps3, do your self a favor and don't fall for the hype, sure the oppo is a nice unit, but FIRST buy your avr and then buy one of them sony 5100s and demo the oppo 105, you compare them in your home and see which you keep... Keep in mind, I promise you in the very near future there will be something "better" for less.... This way when your sony 5100 is outdated it was only $100, you can throw it away...
Also another note on your system, I would look into different subs, I have heard the ML 700's and even when doubled up they can not compare to something you can get for half the price.... Look into Rythmic lv12, HSU VTF2, SVS PB12, ect... My pick is the hsu vtf2, the martin wont come close....
Anyway your money would be much better served in your avr, that DENON is beautiful, powerful, built like a tank, and already marked down $1000+... But even with that, there is very little need for a $1500 avr, when a $500 unit will do almost the same, best buy has the SC63 elite pioneers on sale for around $700....
