New Yggdrasil - First (and second) Impressions

Okay, so I’ve finally (on order over 2 months) received my Schiit Yggdrasil. The unit arrived in exactly perfect condition (i.e. well packaged).

Upon first (and second) listening through all sources/inputs, I would need a stethoscope to discern any difference among my current components and connectivity. I also cannot detect any difference using the phase inversion button.

I suppose the aforementioned is a testament to how good my current system (before/without Yggy) already sounds. :)

I can easily A-B test because the Yggy is hooked in via balanced and my other components are also hooked directly to amp via RCA or USB.

Also, obviously I have NOT let the unit "burn in" for days because I just got it, however, it has come to full operational temperature after being powered on continuously over 24 hours.

System configuration: (Yggdrasil > XLR > Musical Fidelity M6si integrated amplifier > Golden Ear Triton Reference speakers )
all cables blue jeans cables "best" offering

Emotiva ERC-3 CD player > AES/EBU > Yggdrasil
Oppo UDP-205 blue ray player > coax > Yggdrasil
Samsung SMT-C5320 cable box > optical > Yggdrasil
Gateway NV79 Windows 10 64-bit computer > USB > Yggdrasil

I’ll be patient, but if there are any suggestions to "try" in order to hear *some* audible difference, that would be great. Appreciate any feedback you have.

Thanks.

Firmware changes should be free, and it already has discrete Class-A J-Fet buffers with an output impedance of 75ohms and enough voltage out to make just about any poweramp to give it's max output wattage. Hmm?

Hi George. Could you please provide your opinion as to the benefit (or detriment?) to be realized with an Yggdrasil that features "increased line driving capability (600 ohm OK)"? Can you speculate as to how this is an "improvement". Thanks.

To me, what it had already was more than sufficient to be able to drive 600ohms!!! In our system this would never be that low, more like 47000ohms or higher, and at 75ohm and enough voltage from a discrete fet arrangement to clip just about any poweramp, which may even have been a Pass B1 buffer copy or similar. I'd be interested in what this new buffer is.

This is what was the original buffer as stated:
" DC-coupled, low-noise, Class A JFET buffers and summers with high current output capability to drive long cable runs and low-impedance line inputs, such as 600 ohm professional gear"

Cheers George

I believe you know I already have the Yggdrasil connected via balanced (XLR) to my Musical Fidelity M6si XLR (non balanced) input. I know you mentioned SE out from the Yggy could be preferable for short runs, but I like the +6db or so gain with XLR out from the Yggy. With the new Yggy board and its purported "increased line driving capability", do you believe I would have an "issue" if I continue to go XLR out from Yggy to M6si?

"increased line driving capability",

"Increased line drive" does not necessarily mean higher voltage output, otherwise it would have said higher voltage output.
Better "drive" means just lower output impedance with even more current from what was before 75ohm, which I've already said was more than ample.
