Looking for set-up - this ok?

Hi all,

I have an iMac with Roon Core and have been looking at possible DAC/AMP/Headphones combos.

Trying to mitigate cost and emphasise value for money I am looking at the following combo:

Schiit Modi 3 as DAC
Schiit Vali 2 (tube) AMP
MrSpeakers Aeon Flow Open or Closed Headphones

What do you think of this set-up?

Thanks everyone!
