In addition to the various wired inputs, the Denon amp offers BT aptx. Could be a nice feature using a tablet or a smart phone when you are 'on the move'.

The Denon and Marantz amps will drive the Wharfdales with no issues, faire and square

I am using this combo as my second system.

Check out Crutchfield. They should have some good options. 

Get a PS Audio Sprout 100 integrated with an external Apple TV 4K box and your system will sound better that the Powernode and the Apple TV 4K piece will give you more flexibility for streaming music and tv. This is the setup I use in my living room to stream (using Roon) and stream YouTube tv, paramount+, philio, Netflix, and more

I am shocked, no one mentioned SONOS Ray or Beam soundbars. For music streaming and TV watching, I haven’t found anything better. Add one of their wireless sub later for more impactful sound.

If daughter wants to stream Apple Music and hear TV audio through a pair of Diamond 10.1s in an apartment, the right solution is a Sonos Amp, with Powernode Edge a close second. Sonos fully integrates Apple Music, where BluOS uses Airplay to play it.  Other differences are irrelevant to a “non-audiophile”. Both have eARC for TV sound, both will drive speakers fine in an apartment.  The Sonos ecosystem has some outstanding role players for future expansion to other rooms, and their record of not obsoleting gear is impressive.
