Berkeley Dac 2 or PS audio DSD or Schiit Yggs?

Hi all,

I am debating Berkeley Dac 2 or PS audio DSD or Schiit Yggs? 
i have tube amp (Line Magnetic 219ia)
i am inclined to Schiit yggs based on reviews ..
i have no experience with any of these dacs..
please share your experience if you happened to listen all of these and your personal opinion..
thank you all.
well.. i ordered the yaggs!

but very interestingly i found something about my current DAC which i am thrilled about.

while reading about yaggs and its reviews, many stated to leave the DAC turned on for weeks for burn in and to attain peak performance.
Currently i am using Bel Canto c5i as DAC only feeding my LM 219ia tube amp. I usually turn it off after my listening and next day i turn it on back.. after i read about yaggy reviews, i wanted to try keep it on and see how this DAC performs .. for the first 3-4 days i found some improvements but i told myself that it could be just illusion.. but a week later now, i suddenly hear lot of nuances to music.. i am really surprised and its for real, I am hearing micro details and it adds vibrancy to the music.. i am really thrilled.

does it mean i leave all components turned on for ever? i certainly cannot do it to my tube amp (i dont know what will happen) but this is really very interesting

also, my current setup is now sounding so good i am really confused about do i really need yaggy at all? i mean will it really add so much more and i have no idea what that so much more can be??

i am very thrilled and confused..

The digital circuitry needs to reach thermal equilibrium and that is best done by leaving the DAC on.

The main difference is not from the electronic amplification stages as much as it is from the digital circuitry working optimally.

That’s why - even more than preamps & amps - DACs need to have been on for a while to experience their potential.

And it's why you should never allow a dealer or anyone selling a DAC to power it up and play it shortly after you have arrived.  It needs to have been powered up (and processing a signal if possible) for a minimum of 8 hours, IMO.

No manufacturer I know calibrates and adjusts their product/s after a days of being turned on, they all do it at most after one maybe two hours, some even do it cold.

So if things change sound wise after many hours/days of being left on then, they are also not staying in calibration//adjustment that the manufacture did on them in the first place.

Audio Research recommends 400 hours of break in time per input on the DAC 8, so I'm not sure if that's true.  Do they QA their products after this? Heck no.
