Streamer always on?

I thought it might mr_m. The reason I put mine in vacation mode is there might be a couple of days go by when I don't use it , I still spin CD's and sometimes  I would have to power cycle it anyway to reset the ip address. 

Question.

 Do streamers have to break in the way everything else does?

The reason I ask is that it seems to be sounding better after a couple of days.

Break in always helps, as you already noticed, especially if there’s an internal DAC 

FWIW, A wise, very experienced electrical engineer once told me that all electronic gear is designed to run hot. Going from hot to cold & back again is the greatest stress on the gear. Then there's the cost of the electric bill to consider.
