NAD C268 or Buckeye NC252 for side and rear ?

[Gigowatt Film]

Hello,

I hope I'm posting in the right place.

I'm upgrading my theater room to 9.2.6.

My Center, Left and Right speakers (Dali S180) are driven by a Buckeye NCx500 3CH.

I need to drive my 4 Dali S80 speakers (6 ohms, 55-25000Hz, 88db sensitivity) [Side and back] and my 8 Dali H-60 (same specs but a lot tinier) [6 atmos and 2 front wide]

I own a Buckeye NC252MP (hypex) 8CH [presumably 200W for 6 ohms speakers] and 2 stereo NAD C268 amps (Class D, not sure what's in it, but apparently "only" 2x80W)

Should I use the NAD for the S80 or would the Buckeye be better ? Does it matter ?

If I use the Buckete NC252 for Wide, SIde and Back, I'll use it also for one pair of Atmos, and others atmos would be driven by the NADs.

Any idea ?

Thank you for reading :!

So far I'm using the nads to drive front and back atmos.
We'll see...
