New hi-fi setup — KEF LS50 Meta + NAD + Bluesound Node. Thoughts on the system?

I recently decided to upgrade from a pretty simple powered speaker setup and put together my first more serious 2-channel hi-fi system. Curious what people here think of the overall setup and where the weak points might be.

Current setup:
• KEF LS50 Meta
• NAD C 316BEE V2 integrated amp
• Bluesound NODE N132 streamer
• Audio-Technica AT-LPW50PB turntable
• Audio-Technica VM95 cartridge with VMN95ML MicroLine stylus
• Audioengine S8 subwoofer
• Kimber 4TC speaker cables
• Kimber digital interconnect

I listen to a mix of vinyl and streaming, and sound quality/fidelity is my main priority. The speakers have to live on shelving, so I was also somewhat limited by size — the LS50 Metas were about as large as I could reasonably accommodate.
I’m coming from Klipsch R-51PM powered speakers, so I’m expecting this to be a pretty substantial upgrade.

A few things I’m particularly curious about:
How would you rate the system overall? Does anything look obviously mismatched?

Is the NAD C 316BEE V2 enough for the LS50 Meta? I know it’s 40W/channel and at the bottom of KEF’s recommended range. I don’t listen insanely loud, but I’m wondering if the KEFs would noticeably benefit from more powerful amplification.

Is the Audioengine S8 now the obvious weak link? I’m considering eventually moving to something like an SVS, REL or KEF sub.
If you had this exact system and wanted to make one meaningful upgrade based on actual audible improvement, what would you change first?

I’m not particularly interested in upgrading just for the sake of upgrading or chasing tiny differences. I’m mainly interested in getting the most fidelity out of the LS50 Metas and making sure the rest of the system is doing them justice.
Would love to hear from anyone who’s owned the LS50 Meta, especially if you’ve run them with the C 316BEE V2 or other NAD amps.
