DAC "burn in"

post #1 of 53
Thread Starter 
Probably a stupid question but here goes - when "burning in" a DAC is there any reason to have the amplifier on? I assume that the important issue is to have input into the DAC but is there any reason it needs a turned on amp to which to output ? Thanks!

no.


in fact, dacs don't need to be 'burned in'. what, exactly, are you trying to burn or break in?

Thanks for your response. I have a new Valab DAC and it is widely reported that it should be "burned in." For instance, reference thread: Valab Dac-First Impressions. I have read on other forums as well that DAC's should be "burned in." I am not a "techie" so honestly do not know whether this makes sense or not. Appreciate your input.

a lot of people 'think' that electronics need burn-in.

a lot of them don't work in the field and think electronics is 'magic'.

Hi,

I don't mean to hijack this thread but is this article for real?

I am not a techie or an audio professional. I just like good sound coming out of my headphones. But reading this article, it seems to contradict most of the ideas floating around here on head fi.

Should I stop spending time reading threads on head fi and buy cheap interconnects (pg4 of the article) instead?

Thanks

to be blunt, most of the ideas around here are self-serving to the folks in the industry and people just like to 'believe' in magic.

I blame the industry for running out of ideas and selling concepts that are more and more absurd when you analyze them.

the audio field, much more so than video (for some reason) is a minefield of gullibility.

sad, in a way. I hate to see so many people taken for a ride.

any more experienced members have an opinion on this?

I would really like to see a good debate going here. I know alot of people would disagree on what you've said. But unless these claims are backed up by some serious research evidence (i.e. someone can prove that DAC burn in does improve SQ or otherwise), I have to admit, it does sound like a hoax.

For me my Stello DA220mk2 took about 2 weeks to sound ok, before that it sounded really boring and non musical. I suspect the reason for the changes came from the big caps in the DAC.

plain and simple: its psychology.

when you dump a lot of money on gear, you EXPECT improvement. the vendors know that most audio things don't vary THAT much (hey, compare to 1960's, 70's and even 80's audio if you don't believe me) and so they have to argue for why the user may NOT hear a huge improvement from A to B.

"you need to let it burn in, THAT's why you don't see the $1000 benefit you just spent on".

occam's razor. simplest is usually right.

Caps burn in is a known thing. There was no big changes except for the timing (if my memory is correct).

Though my experience is not with a Valab, I found that with at least one device, leaving it switched on, where it stayed warmed up, sonic changes did occur over measured periods, consistent exactly with the experiences of other people who owned the same unit. This included, for example, a period of 50 hours where the treble dropped very noticeably. To add to this, a brand new, unused unit clearly sounds very different to one that has had 300-400 more hours of use. This too had been reported by multiple people. It doesn't, of course, mean it will happen with every piece of electronics.

So, if there is such a thing as "burning in" it has absolutely nothing to do with information going into or out of the unit and only with the unit being left on? It can be turned on without being hooked up to any other components>

but the idea of it taking 'days' is fiction.

again, its a device used by dealers to convince you that the money you just spent 'was worth it'.
