Time to upgrade AV Receiver

Hi All,

It’s time to upgrade, so let’s start with my current setup:

B&W CM10’s front left and right
B&W Center 2 front
B&W 685’s rear left and right
B&W PV1 sub
Yamaha CX-A5000 AV Receiver

Monolith 7X Amp
Panasonic DP-UB820 Blu-ray Player
Sony 65” X900H TV

At the time the Yamaha CX-A5000 was a budget pick based on financials as I was moving from a receiver with built in amp to separates, so I feel this is by far the weakest link in my system and so considering an upgrade and would to hear some expert advice. My budget is ~$2k - $2.5k and I’m going to buy 2nd hand.

The main use of this system is watching TV & Movies, though I’m also building a collection of HD music. If there’s one characteristic of the sound I’d like to adjust with this upgrade is that the sound can become a bit harsh when watching movies (Blu-ray source mostly) and so this is leading me towards Marantz as a brand but I’m open to anything so long as it’s compatible with the latest 4k HD video capabilities and also I use XLR cables.
