Yggdrasil Glitch Fixed

[The Computer Audiophile]

This one shouldn't slip under the radar. Mike at @schiit fixed this a while ago, but only recently announced it. I've had the fix in my Yggdrasil but couldn't say anything :~(

 

I'm sure @manisandher will jump for joy about this (not really) :~)

 

 

Here is Mike Moffat's post in full:

 

"I admit it, yeah, the rumors of modification are true. Over a year ago, we implemented a software modification for the notch which used to be visible at -90db waveforms on all multibit DACs. This modification had a user at another forum in a state of high dudgeon that we could claim our units were high end with such a glaring anomaly. Of course he championed a much more expensive competing unit over and over again which was free of such pox. @atomicbob did not seem to be unduly concerned, measurements champ that he is. I didn't either, completely unconcerned about an inaudible flaw. I corrected it with software tweaks and we have a newly clean -90db measurement.

You may wonder, why didn't we announce it? Well, it goes like this: on our upgradable DACs, we from time to time make running changes, such as the software change above. A few are are compelled, due to parts end of life. The majority, however, are minor tweaks we make for the purpose of improvement. It makes little sense to call an Yggy back for a minor upgrade where $10-$15 worth of upgrades are involved, either for the client or ourselves. So we remain muzzled and do the upgrades when the units come back for more major upgrades.

On major upgrades, such as one which would involve new analog, digi, or input boards, we would implement the changes and let them sit several months to a year before announcing anything. This is so they have time to settle. This is the biggest reason to avoid purchasing a used Yggy. Not that I am attempting anything punative – it is just a system that works reliably, and is fairest on an hourly basis in client cost.

Exceptions are when we offer an accross the line upgrade such as the Gen V USB which pretty much fixes USB, at least until we come out with our own chipset implementation, which will take a year or two. Oops – never mind. These upgrades are inexpensive and effect huge change. So we offer them.

Are we going to offer analog upgrades? Is Apple going to upgrade their phones? Of course. The difference is that we will conceal our upgrades for some period of time before we offer them."

This means you can buy any new Schiit multibit DAC and have no worries about the infamous "glitch" or any impact it may or may not have on the audio you listen to.

 

It also means that my Yggdrasil has the same modification.

I received a new DSP chip for my Yggy when the Gen 5 USB arrived. Not sure if the two were related or what.

Chip and board.

Not sure if the DSP chip was required to make the Gen 5 board work in the Yggy. Anyone else know?
