What do you do when you have a bunch of used Yggdrasil Analog 1 cards that are gathering dust? Well, if you're us, you put them in an otherwise new-production Yggdrasil so we can give you a chance to get our best DAC for a very attractive price.

"But wait, used?" you say. "What do you mean by 'used,' and what do you mean by 'Yggdrasil Analog 1'?"

Good questions. 

For those of you who are new here, Yggdrasil has had two different analog cards during its lifetime. The first, Analog 1, was replaced by Analog 2 a couple of years ago. Analog 2 have a bunch of internal changes that make them sound better, but both cards use the same stunningly expensive Analog Devices AD5791BRUZ D/A converter—two per channel, or 4 per Yggdrasil.

So, after upgrading a bunch of Yggdrasils, we have a lot of used cards. These cards have expensive chips on them. So, we came up with a crazy idea: put them in new production Yggdrasils and sell them for less. That's Yggdrasil GS.

If you decide to get an Yggdrasil GS, you get:

1. Two Analog 1 cards in an otherwise complete new-production Yggdrasil.
2. New firmware that makes the Yggdrasil GS measure almost the same as Yggdrasil (see the APx555 reports for both products). Yes, we still think the Analog 2 sounds better. Yes, we're weird. 
3. A full 3 year warranty (a couple years less than Yggdrasil).
4. The older Gen 5 USB card rather than Unison USB. This may be a plus if you are using an ancient version of Windows, since Unison USB does not support any Windows OS prior to Windows 10.
