After reading through this thread and others, I've put in my Yggdrasil order.

In the process of reading up on the Yggdrasil, I found one bit of information that might be interesting to folks asking earlier in this thread (or was it another one?) about using the RCA outputs rather than XLR.

In a list of Yggdrasil tweaks (http://www.tweakaudio.com/EVS-2/Schiit_mod.html) I saw the comment

Quote (selected)
If you are using the coax (single ended rca's) outputs then you need to take the single ended signal from the xlr connectors for much better sound.  There is a summing circuit after the balanced circuits that is not super transparent.  This mod eliminates this circuit.  You can get or make adapters to use (you use just pins 1 and 2 and you leave 3 unterminated....important!).  Another way would be to put xlrs on your cables that use just pins 1 and 2.  Another even more transparent way is to harwired (more on this later).  This mod will make the DAC way more transparent and clear.....mucho better.

I was intrigued, so I asked Schiit if that was wise/possibly a good idea. They replied

It would be fine to use the XLR to RCA cable to bypass the summing circuit. Make sure the cable you use does NOT short the out of phase (Pin 3) to ground (pin 1). It does bypass additional circuitry which is generally a good idea.

Cool. So I asked Pete at Triode Wire Labs if he could make me a pair of his interconnects in this configuration. Yep, he can (and I'm sure others could as well).

I hope this is useful and interesting to folks. It sounds like a good way to reduce any angst about having to use the RCA outputs on the Yggdrasil. I have no direct knowledge that it makes a difference (since I won't even get the DAC until August if Schiit is realistic about the timeframe on shipping.)

don't forget to remove part of the chassis and put stickers on top of the caps and chips.

Yeah, I'm sure 1500VA is adequate.. but I don't want to spend that much if I can get away with 1000 or 850.


The specs on their site says it only uses 35W so even if you make allowances for an abysmal power factor even the 850VA will be overkill.

I was ignoring that part! I don't even know if a quantum sticker would be there if I'm not looking at it.

But Schiit seems to think the XLR to RCA idea has a basis in reality. I still have no idea how much difference it makes until I have my Yggdrasil and cables to compare.

It might.


Will the use of only one chip (instead of two - per channel), but without the extra summing circuit outweigh the full use of two chips with the summing circuit (to SE input). I can already tell you that I prefer the balanced output via 600 ohm / 600 ohm transformers into a single ended input. The transformer sounds different than the FET summing circuit. Some things better. Some things worse. But in a way that I prefer.

Marv,
am confused about the 600ohm transformers pieces.   p:8
due to my wiring ignorance.

a few posts back in this thread you said:

It would be better to take Pins 2 and 3. Most XLR-RCA cables do this already.

Bad idea with Yggy. Not going to explain it.

so to (re)ask the obvious:
one should NOT use typical XLR to RCA cables if attempting this with Yggy?

and only try with those 600ohm transformers installed?

Basically XLR to XLR or phono to phono or XLR to phono via pro box with transformer. No explody anything.

I like to keep things simple and as designed.

Mates,

facing a new situation with the Yggy...Until Wednesday everything was fine...I then upgraded my iTunes to the latest version (12.2.1.6 or something similar).... since then, the bit rate indicators on the Yggy will not light up AND no there is no sound. Have a couple of Macs (mini and MBA but both have the same iTunes version). Powered the Yggy off and on a few times but no dice. The normal clicking sound I hear when the Yggy gets the input signal is absent. I use Amarra and select the Yggy through the Preferences option... any body faced a similar situation?
