The first 100 hours don't bring it significantly closer to end of life. Most solid state components, if they are going to fail, do so in the first hours of use. It's the same with RAM, CPUs, etc. All of that stuff is tested, i.e. burned in, like that.

Whether or not sound changes as you test a DSP is secondary. I've worked for a couple of large semiconductor companies, and this kind of testing is part of the process. Not just for complex systems, but for individual components. By the time you hear your new DAC, it's had power running through it for a while. Every man wants to feel like he's the first in line, but no one really wants to deal with something inexperienced. Trust me.


True, 100 hours of use are insignificant relative to a 20 year warranty.
Not trying to argue with you, just saying, I agree, the concept of failure within the first hours of use has been proven by various reliability studies.

I guess some of you folks have never heard of the bathtub curve describing component life span, eh?  Although Google is no substitute for education, it can help the novice find (albeit sometimes confusing) information.  And look up MIL-STD-833C while you're at it.  Or not, I really don't care.

Of course that's part of the problem in the audiophile community, in my opinion: someone finds some electronic or electrical phenomenon that exists and because they really don't understand the way they think they do, blows it out of proportion into the *THING* that must be done.  When in most cases it is simply moot to the actual audible performance of a piece of gear.
 
I end with two of my favorite quotes.  First is audio pioneer Henry Kloss, who said, paraphrasing a little: "Everything that can be heard can be measured, but not everything that can be measured can be heard."  And second, my friend Kevin Haskins who created some very nice drivers with Adire and Exodus Audio: "Inaudible is inaudible and you don't get extra brownie points for being twice as inaudible as the next guy."

But in the era of online research and people buying things unheard over the internet, you may make extra sales.

Yeah, I'm wondering if they're managing to get 20 bits out of the discrete resistor ladder of the Yggy, myself.  That borders on the remarkable.  You know, near LOLOLROFLCOPTER country...

 
Oh - It should be easy, after all, the new Sigma Delta chips are a true 32 bit design ...
 
 
 
Did I get my "LOLOLROFLCOPTER" moment for that one ?

  i am curious when mighty Yggdrasil will wake and get out from his dark cave...
(-:


Yggdrasil is a tree.  Or, the Horse of Ygg.  I guess a horse could live in a cave, but I don't think Schiit was going for an etymological exercise.  I think they meant The World Tree.  That cannot come out of a dark cave.  A dark cave can come out of it, though.

I don't think you're arguing with me at all, since you said the same thing I did.

Exactly the reason that initial testing makes sense.  Changing sound is not part of the rationale.  Unfortunately, like religion, some people believe it and proselytize, convert others, and cause mass hysteria.  We're mere moments from someone flying a turntable into an audio rack.

  i have had 3 DACs with  iterations of that chip...with incredible multiple stage power supplies and even Back Gate caps etc...and always found the sound lacking in one area or another...
 
and you should read this to appreciate/understand what the single / double crown urban myths really are about and that non crown tda1541 perform as well

 
Whoops - looks like you missed the link! I am fairly familiar with the 1541/a/s1/s2 debate though - this link explains the difference (and it is a VERY interesting DAC - utilising the 1541a at up to 192kHz!!):

There is also more info here, but it is a LOT of reading:

So all the manufactures that recommend the user to burn them in “don't understand the way they think they do”?
 
Okay I can hear that some gear have better image or a profounder soundstage. Which measurement will indicate a precise image or a deep and wide soundstage? Is the amp/dac/headphone with the lowest measured distortion and jitter always the most transparent? If not what kind of measurement will indicate this? The distortion and jitter (level and sort of it) will to some degree indicate on clarity and transparency, but far from give the full truth IMO.

Guys, I am not guilt free here. I made a post on capacitor burn in...
 
But this discussion is getting really boring!
And it is off-topic in an important thread. I put a lot of effort into the impressive scaling fonts above so can we please move on.
