When I got my Direct Stream DAC, I queued up some music from Tidal using Roon. I also turned on Roon radio so it would continue to play when the first album I chose ended. I left this going constantly for > 200 hours, sampling the sound quality every day when I got home from work.
Different devices can be broken in differently, for example on the DAC I didn’t bother to turn on my pre-amp so no one needed to listen to whatever is playing.
When breaking in other devices, like speakers, you would naturally need to actually play music through them, and the more varied the music the better.
My new PSA DSD DAC Sr has been burning in for 540 hours continuously and is 54% complete. My new Luxman Integrated amplifier, 509X, was burned in for 375 hours before settling in. With an amplifier, pair of speakers, or speaker cables one can wire the speakers out of phase and place them face to face running FM white noise or other white noise source. This results in minimal sound in the room while providing for an effective burn-in. With a tube amplifier I prefer to be in the room during burn in just in case of a tube short, gassy tube, failed cap or bias resistor problem.
Some gear like Conrad Johnson use Teflon caps that take 500 hours of burnin. Even CJ recommends 500 hours. I replaced all the PIO caps in my BAT preamp and I thought I ruined it until the caps had 150 hours on them and then the preamp was back to its great sound. It sounded bright and edgy until 150 hours or so.
The pair of M700 monoblocks I just bought sounded awful for the first several hours, peaky, bright, edgy and closed in, then it started to smooth out and it keeps getting better. I have about 50-60 hours on them and they keep getting better.
How do you know so precisely that its 54% done? Did I open another Pandora box? I have been blissfully using my PS Audio Sr without doing any burn-in for the last 2 years. I might have listened for say 100 hours.
@karthick Burn-in is a very odd phenomenon. I’ve experienced it over and over again. Yes. leave components on 24x7 playing music if possible. Only thing I turn off is my Tube amp.
If component sit for a long time it takes a while for them to burn-in again. Not the same as the first time you turn it on.
On the same topic. If you bought new speakers after playing them for 300ish hours really hammer on them for an hour or so. Make sure you are not clipping. Wear ear protection or leave the room. Really does wonders.
No, I’m comfortable with 300-500 for the DS. Somewhere in there the changes are probably less that the changes in our hearing day to day or the cleaner power in the evenings. Some have reported longer times like 800 or 1000. I’m not going to argue, but I know I can’t hear a difference out there.
Thanks @Elk. So I presume that I can run it straight 500 hours by playing Roon radio and not turning on the amp. That would be ~15 days of continuous play to get into range (i already have 100 hours on my DS).
Are there any particular type of music? or anything works? I know the question looks dumb but audio nuances seems to be never ending, better later than never!
No offense to Mr. Smith but at 1,000 you will hit magic all of a Sudden…Like a new world all of a sudden…I ran mine for 46 days straight…and it is still not off…not ever…your 100 hours have be over a 2 year period…I would ignore that 100 hours…too spread out
when the attenuator is in, your vol will drop 20db or 40 vol clicks, and your vol will be able to go to 106, on your remote is a Dac Level button, press it and an L will show up at the bottom of the DSD’s screen.
