Schitt Audio Still in business???

@psickerson No, I own a Gungnir Multibit (aka Gumby), but have a handful of local friends who own Yggys and I listen to them regularly. The break-in is so dramatic that it is counter-productive to listen for the first few hours and draw any conclusions. 
This issue cracks me up in how often I read reviews where the writer listens to gear, points out a flaw, lets it break in, then says that the problem went away. I guess if they didn't do that those writers might not be able to fill their columns. Cheers,

Does break in mean just turn it on or does it need to have:
1). a source cd/streamer running attached yggy?
2) output of yggy attached to amp?
3). Amplifer on
4). Speakers attached to Amp

It is a strange requirement and I have not seen what is actually required for break in

Id prefer to not leave my tube amp running for no reason.

You can leave amp off if you want. As long as the input signal from source goes to the Yggy, and the cables are connecting its output to the pre/amp you are fine. You just want a signal going all the way thru the new device.
As a side note, don't ever run a tube amp without a speaker connected or you could damage the amp. Cheers,

Thanks Spencer .  I will commit that last point to my hopefully long term memory.

Ideally you’d want to have your amps on also actually. You want the signal going all the way through every piece of solder, wire, capacitor, etc. The DAC has small amps/power for the output signal that you want going through it’s paces during break in, and out through the last bit of circuits and wires and such. It’s not just the actual DAC chip that is the only thing getting broken in. I mean you have an entire huge analog section that is like half the DAC after the DAC chip that needs to be broken in and have a signal going out through it to some amps. While it will mostly break in still with the amps off I feel I got better results with them on. Without the amps on I don't think the signal has any place to travel and be used and is not actually traveling a signal through if there are no amps on to use that signal. I’d alternate between leaving them on and having them off since I didn’t like having my amps on constantly.

But yeah this thing really does need 100 hours or so at least to break in. Mine was dramatically better after about 100 hours. Supposedly it takes up to 400 hours to be 100% done some have said. Seems minimal so far after 100 though. But I think I read that others have said it can go in spurts even after the 100 hours.

It’s definitely an incredible DAC. Mine benefited by using the USB regen. The regen still makes a big difference even on the yggy.
