It is possible that the Ygg is built into the modular form just like the new Bifrost? Then upgrades in the future would be easy. It is because shipping fees are so expensive for overseas users.
Yes... The Yggdrasil is built in a modular form and meant to be upgradable, schiit allows the USB modules to be user installed, but not the analog cards..

I just installed the Unison USB card in the Yggy.. Took a little over an hour mainly because I didn’t want any screwdriver slips or scratches marring the finish or the screw heads. The right sized screwdriver is required as some of these were torqued down a little too much.
The back panel requires you to remove screws and a nut for the BNC out, was Careful and did not scratch the panel on that one, was tight and thin.. New card fell in place, fastened In place, I put it back together slowly..
Set it up in the system, No usb option to select and no rate indicator lights, and no relay noises.. ??? but the OS showed the Unison USB card installed ? only the selector light was on, and I couldn’t select them all.. ?
So, I went back in, to find I missed a row when reinstalling the ribbon cable. looked fine from the limited view you have when connecting..
Carefully screwed it all together again..
All is well.. its playing now from a cold system.. but I can already hear one difference...
I need some warmed up listening time.. looking forward to it..
Stay safe..

A quick followup to the unison usb upgrade from above... It’s good.. real good. I immediately noticed the difference even with the system being cold,
Everything was more crisp, like looking out a first time cleaned 8 year old window.. Several hours later I sat down and listened to some of my well played
favs.. Cleaner view to the music overall.. I noticed more bass, which I would never have expected. It’s not that it’s more, but better defined so the beginning and ending of bass notes are more defined than they were, stands out. everything seems better defined, by a lack of grunge I didn’t realize was there. better overall presentation ..
Once again, the schiit folks have given more than you would expect. Anyone sitting on the fence about this upgrade should reconsider.. IME..

I was thinking of doing this too. Can I ask what HQPlayer conversion filter you found best with the Yggy, for PCM?
Sure, you can ask... ha. I like the Sinc-L and the Closed Form M, I think it is, going from memory here, but I think those are right.

Is anybody using balanced power with yggdrasil and can attest to sonic improvement as a result?

I am using an AC balanced isolation transformers to feed my audio system.

While I can't claim a SQ improvement per se, it does afford a more stable AC voltage feed for the whole system and the it does seems to operate in a more consistent manner.

I was worried that it might have had a deleterious effect on the power amp(s) but such isn't the case.
And since the JggyB draws such a small amount of power, I doubt if used by itself alone on a isolation xfmr, it would have much effect either way, unless the power is 'dirty' or the power delivery is problematic in some way (poor AC connections etc).

Just my 2¢

JJ

I believe that @gdhal is referring to using the balanced audio output, as opposed to single-ended. The question's wording is a bit confusing.

I use balanced power for my system, a BPIT.. I can attest to a lower noise floor throughout the system. it Allows for more contrast and emergence of music from a dark quiet background.. I never want to be without a BPIT.. Common mode rejection is real and it works.. Some Say it also benefits from the large transformer having stored energy available for demanding transients.. I haven’t just tried it on the yggy by itself..

ok.. @gdhal I was using single ended at first because I will end up that way since My amp is SE. But recently I switched to balanced from the Yggy > Freya
and it sounds better.. it really made a nice difference. Others have noted it too, including schiit..

No. JJ has it correct. I'm meaning balanced AC power, not balanced interconnects via xlr.

I too use balanced XLR interconnects from the yggdrasil to my amp.

I was just reading about Yggy's measurements over at that audio science forum yesterday. I have only skimmed through the first page of the thread, but the bass frequency response did seem to measure better (flatter across the spectrum) out of the balanced XLR outputs, than it did out of the single-ended RCA outputs.

The bass fell off noticeably with the SE outputs, when compared to balanced. I assume that most of you people have already seen this:

Apologies (again) if this has already been discussed ad nauseum!

Subjectively speaking, the XLR/balanced output on the Yggy 2 is noticeably better than the RCA/SE.
