Break in for new DAC

@westcoastaudiophile "most equipment needs break-in to sound best"

Yes, it really does. Just because you can't hear it, doesn't mean it dosen't happen/exist.

Also, you say - "aging (break-in), increases digital circuits jitter/s, negatively impact switches/drives strength". What evidence do you have for that? It's a new concept that I've never heard before, and I can't see/believe how that can be the case? Has anyone else heard of that?

 Any Topping d90III Sabre MQA DAC owners out there?  What was your break-in experience?  Thanks.

@nubiann  Electronics conversely benefit having some continuous power. Components like transistors, op-amps, and voltage regulators perform best at a stable operating temperature.

Just  comment on this idea.  I run Hegel mono blocks and have wondered about the concept of "always on".  Hegel amps do not have a Standby mode.  When questioned directly on this issue, Hegel responded "when not in use, turn the amps off.  Keeping the amps continuously powered does nothing but shorten the lifespan of the product.  The amps warm up in a matter of minutes"   I know there are two opinions on this subject, but I'm going to listen to the manufacturer.  Cheers. 

Somewhat tangential but ... some years ago I purchased a used Aesthetix Romulus Tube CD player that had been broken in, but not plugged in the previous 9 months...I called Aesthetix and they said simply having it on stand-by for a month would bring it back to full performance level...but certainly encouraged me to use and enjoy it ...

I have Denafrips DACS and in my experience, they seem to sound better till around 300 hours, around 20 days of daily use. THEN it became constant. 

Note: I don't turn it off at all
