The Denon AVR-X1700 supports 120Hz 4K and VRR gaming on I think three of its HDMI sockets. It's a good choice at the money if you want to pass a PC or console through it to the TV.
You do have some other options though. With eARC on that Q90 TV, and an eARC-equipped AVR, it's possible to have a source output LPCM in up to 7.1 and send its signal to the TV first, then have the TV send the audio to the surround system. This opens up the possibility to look at older AV receivers. It also gets around TVs which won't pass DTS and DTS-HD via their eARC connections.
I would agree with Hornetstinger about the Wharfedale and Q Acoustics main being good. These British designs are evenhanded and good for music which is a bit of a trial by fire for a lot of AV speakers. Polks (an American speaker brand) tend to have a bit of a reputation for boom and tizz. Our cousins over the water are learning just how good British speakers are. Reviews in mags such as Stereophile are generally very complimentary about Wharfedale and QA.
Yamaha for speakers is more difficult to pigeonhole. At the high-end, especially for the Japanese home market, the company makes some superlative speakers. Unfortunately, the UK and Europe are home to superlative home brands by the shed load, so it's an uphill struggle trying to convince dealers and their customers that Yam high-end speakers are what they should buy instead of KEF, ATC, B&W, PMC, Tannoy, ProAc, Wison Benesch, Quad, Wharfedale etc.
Yamaha had brief moments in the sun with some fairly accessibly priced products. Back in the 80s, folk started seeing
NS-M10 monitors popping up in recording studios. These were being used as nearfield monitors; speakers very close to the engineer when mixing. To the uninitiate, this was like some badge of approval. "If it's good enough for the people producing and mixing my records..." The irony was that this was the exact opposite of why they were chosen by the engineer who kicked the whole thing off. Paraphasing his words, if he could make a mix sound good on these then it would sound good on anything. The frequency response may have been all over the place, but the thing they did exceptionally well is timing.
Pro gear and Japanese home market product aside then, what that leaves us with is Yamaha's more budget oriented ranges.
Products such as the NS-P and NS-F are designed as companion products to electronics. In simpler terms, they look like good value in order to encourage someone to get their wallet out. When AV receivers were available under £250, Yamaha package a budget receiver with their NS-P
5.1 sub/sat kit. It was everything you needed for maybe £50-£100 more than a Panasonic/Samsung/LG/Sony DVD-Blu-ray home theatre kit.
The front speakers from the NS-F51 package are available as a standalone purchase for £250/pr. They came out in 2017-ish priced at £150/pr. Accepting that there's inflation and market changes, these are still made for a similar cost as when they sold for £150/pr, and cheap floorstanders are rarely a sonic bargain. Although smaller, the Wharfedales and Q Acoustics are better screwed together and cleaner sounding, albeit with a little less bass.
