iBasso DX260 MkII coming tomorrow what do I need to know?

Hey peeps,

Had an A&K Norma SR15 currently for sale on eBay.

Have replaced it with an iBasso DX260 Mk II coming tomorrow.

Any tips regarding settings, tweaks etc welcome.

I have a 1tb micro sd card in Fat32 with 600GB of Flac tunes ready to go.

TIA
