Both my Schitt Yggi+ DACs took 1 month of heavy playing to settle. My Aegir, which is used as a headphone amp did not take much time. It runs hot so maybe that helps in the components settling faster.
BTW - I put together a new headphone system 2 days ago after having some of the components idle for the longest time.
Schitt Aegir 1 amp | Schitt Mjolnir v3 preamp | Schitt Yggi+ Less Is More DAC | RAAL CA-1a phone | RAAL TI-1b interface
I had other DACs in the chain before and it was sonically close to my RAAL VM-1a tube headphone amp, but really not as nice. However, now with the LIM DAC I am almost at the VM-1a level. A shocking surprise and one that allows me to move the VM-1a to another room.
The Aegir is one nice amp.
