Receiver Help

An Arcam AVR21 was just listed nearby for $1350. I’m wondering if this is the best solution for me, or if I should spend a bit more money to get a Denon or Marantz.

Here’s what I currently have: Speakers: Kef R11 Amp: Arcam PA240 Streamer: Arcam ST60

I plan to start expanding my system, probably starting with Kef R3 metas that I found for $1500 to use as rears. I’d like to eventually add Atmos speakers, but that won’t be for 4+ years until I own a house.

Perhaps the Arcam would be best to match the aesthetic of my other Arcam components. I just need a clean receiver that will give enough power and clarity to my system, as well as one that has DIRAC/some other form of room correction.
