I actually don't believe it's always better... The impressions myself and others gave mentioned brightness. I also believe 1dB of frequency response in a certain area can be described as dramatic by some, while others may not even notice the change.

In the case of the Multibit Schiit DACs, the chips themselves become more accurate as they reach thermal equilibrium. This results in higher dynamic range, and less jitter; both which may be responsible for the audible improvements. (See the Yggdrasil measurements available from Atomicbob).

If you ever get a chance to experiment, try swapping some amplifier capacitors with ELNA Silmic II capacitors. Their burn in behavior results in changes all over the place for a very long while... I don't find the gear to be incrementally better sounding throughout their first 60 hours, but they have a very signature response once they're settled in that sounds very nice in my opinion.

Oh also Schiit burns in their DACs for 24 hours I believe. Probably results in changes from brand new, but in my opinion, the sound continues to change with further burn in.

The primary purpose of burn in for electronic components is to minimize any component failure after it leaves the shop.  Most components that fail will fail within the first few days.  This really applies to all electronics.  Secondly, for DACs, it ensures the components reach thermal stability, measure, and sound like they're supposed to.  This all happens in the shop before it gets to us.  Lastly, it gets thrown on a truck and can take up to a week to reach its recipient.  Any turn on time to reach thermal stability has been essentially washed.  These multibit DACs are a peculiar breed.  They're precise instruments that do require time to settle thermally.  I personally noticed degradation after a certain period with my Yggy then back to good again then better. The chips are finicky and require very precise regulation to perform at their spec.  
 
For amps, especially tubes, just turn it on a few minutes before you're ready to listen.  They take far less time to reach their quiescent operating state.  These DACs tho.  Yes, it does take time and sound does vary a good bit over that settling time (good and bad).

Ok everyone, a few pics of my setup, for those inquiring minds!!  LOL!

I'm certainly willing to be proven wrong,  but I'm not holding my breath.

YEP! It's all in my mind, and it sounds GLORIOUS! Movies are pretty sweet too!!
 
Cheers!
 
P.S. My Yggy is on order too! Hopefully it will ship soon, as they are now in stock. I will DEFINITELY be using Yggy on the tweeters.
I feel Yggy will give the best bang for the buck there, as high frequency information is predominantly, but not ENTIRELY, where we process focus, soundstaging and imaging, and ambient cues and decay comes from. Bass also can play a vital part in soundstaging and ambient cues.
Did you know that bass actually starts at the tweeters? A friend of mine did some impulse response measurements of a kick drum, and that the kickdrum actually started out in the high frequencies. I forget exactly, but it was well over 20kHz. Interesting....
Maybe in the future, after I save a few more pennies and dimes, I can upgrade the other 4 DACS to Yggys as well!

Sorry I doubted you. That looks like quite a esoteric setup. 

Very cool setup.  Never doubted you.  You always sounded like you knew what you were talking about from tech standpoint.  Next step: cable management! Ha.  Very nice setup.

I'm willing to bet it sounds like Schiit.

Interesting what you've all got going on...just...wow hahaha. Also the cable management makes me want to beat you over the head with a stick! If not for the management but just to be there in order to hear that....*drool*
 
I don't know if i should laugh, cry, or otherwise. First thought was "this guys nuts....just nucking futz" and then I remember how much money I've got tied in across three cars....I'll go back in my corner now hahahaha.

I'd be interested to know details on your approach in the digital crossovers.  A lot of potential there.  Given how many you're using, I'd love to know how you optimized the phase coherence between them all.  Sorry if I'm getting off topic on the Gungnir thread.

With a setup like that, I hope you never have to move. Setting it all up again would be a nightmare.

I accept now that it exists.  Hope it sounds great.  This is a system that is certain to be replicated by - no one ever.  That's not a putdown, just that your system is "sui generis".

TubemanRQ thanks for posting them, I can see now why you were so reluctant

TubemanRQ, thanks for posting the pictures. That looks like a similar driver config to the Linkwitz Orion, except with an extra midrange and a different tweeter. Did you base your speaker on Linkwitz's dipole speaker work?

It sure is GLORIOUS!  I would love to hear how your system came about especially the thought process. Ever think about starting a thread in the DIY section? 
 
I have no idea what the function of those things that look like metal shutters are, heat sinks? Baffles?
 
Thanks for posting pix. It was messier than I imagined, but about what I expected.

Bravo! It's a kludge, but I'd love to spend the day listening.
