Schiit Yggdrasil Upgrades

the red wima cap they use are a weak link 2 friends in the U.K have upgraded to these far superior Coupling caps

Hate to inform everyone, but there are no coupling caps. The Schiit Yggdrasil is direct coupled from D/A converter chip all the way through to the outputs with dc servos handling any dc offset.

Quote Schiit:
Analog Stages: Fully discrete JFET buffers for balanced output and discrete JFET summing stages for single-ended output, direct coupled throughout.

Schiit hold to the theory that the best coupling cap is no cap!

The Wima cap that was changed was probably a power supply bypass cap for electrolytics, and the red Wima is about the best you can get for this duty.

There is 6 Wima caps per channel 12 in total. 
Without question in the signal path. I heard both Yggdrasil units with Wima caps 
And with the Amtran caps.  Not one person picked the sound with the Wima caps.
The proof is in the listening.  I have nothing else to say on the matter .
I was just relaying the upgrade option .It is up to you what you choose to do or not.

From the Yggdrasil circuitry explanation
"direct coupled throughout"

Sorry but direct coupled, means it’s dc coupled throughout, this means, "no caps" in the signal path, sorry to say someone’s having a lend of you. The Wima’s are all to do with power supply by-passing.

Personally I think Wima caps are hugely overrated and over-relied upon. Cornel Dubelier are much better sounding in electronics IMHO and not much more expensive.

I think there’s a little misunderstanding. DC or direct coupled means that the signal path is not interrupted by a capacitor. This means that the signal relies on one side of a cap as input, the other as output. However, that’s not to say there are not caps shorting to ground from the signal. Bypass caps in the power supply, or signal can affect the sound quality, but we expect it to be to a lesser degree than coupling caps.

The only way to know for sure is to trace the signal.

Best,

The only way to know for sure is to trace the signal.

Good luck with that, being a multi layered PCB.

Or you can believe what  Mike Moffat, formerly of Theta said about the  description of the circuit topology, that the Yggdrasil:
