I have a situation very similar to yours. I'm using a $2000 A/V receiver for multichannel sources and wanted to upgrade my front speakers with higher-quality electronics; primarily for handling stereo sources like LP, SACD, Tidal.
I've spent two months reserarching in depth the best way to do this, and have spoken to many first-hand users on various forums, as well as dealers, and even product designers.
MY final conclusion is that the Ayre integrateds may be the most flexible way to implement such a configuration. Multichannel input -- Netflix, DVD, Blu-ray, 5.1 SACD goes directly to the receiver and the receiver's FL/FR output then goes to the integrated. The stereo sources route directly to the integrated, never passing through the receiver.
Unlike a lot of integrateds, the Ayre EX-8 has all the functionality needed to make this work. And its headphone amp & optional DAC seem to be garnering very high praise, even compared to popular (and costlier) alternatives like the HiFI Rose DAC/streamers.
How Ayre produces a 24lb 100+wpc integrated with so much connectivity, outstanding sonics, and Class A/AB operation (what, what, not Class D??) operation is beyond me. If you already have one of these integrateds inhouse, you may be able to accomplish everything you want without buying any new gear.
If it were me, having owned lots of gear similar to your own over the years, I would never replace Ayre components with Denon -- and I'm a big fan of Denon at its price point. Ayre is in a whole different class, sonically. The Ayre integrateds are modulare & the company will even upgrade many older units to, e.g., the newer EX-8 2.0..
Not sure if you've already settled on a new configuration, but I wanted to at least mention my own recent experience.
