DAC break-in...

Thanks @audioengr
Helpful explanation.

@twoleftears
I agree that acclimation plays a role in the "break in" process. The entire listening experience is such a crazy complex blend of electrical, mechanical, and psychoacoustic phenomena. It’s a wonder we aren’t still listening to wax cylinders.

I have always felt that acclimation plays a very large role.  I think that manufacturers sometimes specify long burn in times in order to entice a purchaser to continue acclimating past the return period.

What nonsense. Break in or forming of dielectric in electrolytic capacitors is only necessary after lengthy storage (many years)

Roberjamin and a few others are correct  seperate everything is good but there are great players out there . I have a Lumin D1 
player which use  dual Wolfsons best dacs and optional Much much better power supplies that Transform this award winning player to something up there with many $8-10k units 
myself bought the Linear Tube Audio Linesr 12 volts powersupply 
a very good power cord is instrumental . I am using a Verastarr Grand illusion Dual Copperfoil.  Synergistic research I don’t care for much of their hype ad ons. But their Blue fuses are very good .
these little things count . MojoAudio make a Very good Linear powersupply I may try   Getting back to a player  you have a external hard drive  plugged in the Lumin library app is Excellent.
plus it has a Roon, Tidal,with full MQA capabilities for under $3k 
not counting the power cord or upgraded Umbilical cord which is 
also Verastarr. You have a versatile music setup , even digital music is possible . Their is other players also. But this player is very analog sounding in many ways.
