Over the many years I have been at this, nothing enters my main system until at least 200 hours are on it, (depending on the device/cable, 500 hours sometimes). Yes, I know some of you don't believe in burn in, but I happen to...strongly.
I have a separate little system in one of my record rooms that I use strictly for burning in of gear/cable.
I did listen to my Sonica right out of the box in my main system and thought it was a little closed in and dry. Took it out and returned it after 200 hours and WOW, did this little guy sound spectacular! I left it in and did notice a very subtle change or two, until about the 500 hour mark, then it settled in quite nicely.
I highly recommend this DAC. It's nice to find something that is not very expensive and performs well above that price point. I've had tons of equipment through here and this doesn't happen very often
