Schiit Yggdrasil A1 versus A2 Upgrade


Anyone have an Yggdrasil A1 that they have owned and then upgraded to the A2 version? I currently have an A1 that I have owned for a couple of months. I bought it from the original owner so I know all its history. Its fully broken and been constantly kept on. Initially I found that leaving the Yggy off between listening sessions simply make it sound horrible. It needs to be at working temperature all the time.
Upon extensive listening to digital sources and comparison to vinyl and RTR the Yggy simply doesnt come close. Lacks dynamics, bass!!!. 3D space, lacks punch and power. It sounds like a compressor is attached to it. It has lots of detail and a rather balanced sound to it but thats about it, I dont see what is so great about it. Its lifeless, has no sparkle, it doesnt come out and grab your senses. its boring.
I sort of feel I am at a point of selling or upgrading. Heard so many good things but now that i have it Im not sure an upgrade will fix all the Schiit that Schiit screwed up on in the first design. Its also annoying paying for upgrades that essentially are design flaws.
I was hoping some of you members had done the upgrade to A2 and had some A1 to A2 experience you would like to share.

What is your source for the Yggy?

Interesting.

My Yggy sounds nothing like what you describe...either with the original A1 or upgraded A2.

In fact, if I connect the Yggy to my Esoteric UX-3Pi universal player via coax digital cable and then A/B the two, the Yggy comes very, very close to the Esoteric in sound quality: dynamics, bass response and inner detail.

I use the Ydddrasil's balanced outputs. They sound better than the RCA outputs in my opinion.
Repeat, how are you presenting data to your Yggy? USB...COAX...AES/EBU?

I have been using coaxial from a CD player for the first little while to listen to as thats what was broken in being its a used DAC . So I wanted to get a good listen before I made the switch to USB and computer as my source. The USB has never been used from the original owner who I had bought it from. I'm not sure how long the USB card should take to burn in but I'm guessing I have 20 hours on it. It is better and has more bass but still could be better. 
My biggest complaint is the lack of bass and power behind the music. It sounds weak, compressed.
  
I used the Yggy's XLR outputs with adaptors to rca cables direct to my Assemblage ST300B amp
If you don’t like it now, then there’s no magic tweak or connection that will make it better.
Cut your losses and move on. There are a lot of DACs in the world.

FWIW, my Yggdrasil sounded great out of the box with the USB 1 and Analog 1 modules. It has gotten marginally better as I have added the Analog 2 module, and then USB 2 and now USB Unison upgrades.
 
Apparently rumours have it that the A1 is lacking bass, I agree. I am trying to get others to confirm its character from A1 to A2 to see if it is worth the upgrade. Right now Its not exactly what I like. 
There are other traits Yggy has that some have mentioned that arent that favorable in the A1. 
So upon the A2 upgrade what does it improve from A1. Some say it gets really good after upgrade and you said marginally better? 




I would suggest buying a new one. Compare it to what you have.
You can return the new one within the return period for a refund.
Once you compare the two you will have a better idea how to proceed: upgrade what you have, sell what you have, keep the new one, return the new one.

You are aware Schiit sells a version with the Analog 1 card, yes? You could buy that version to compare and listen for differences. This would be more apples-to-apples.

Either would eliminate guesswork on your part.
I already have the A1 version. And I dont feel like spending another $2600 USD plus duties to Canada. 
The A2 upgrade would make more sense if members actually stuck to the point of the thread. 
Thats what I am trying to do, determine the differences from members who have owned both in an analytical and musical description. 
I have owned all versions. The improvement in my system between A1 and A2 was marginal. Bass didn’t improve that much from A1 to A2 as it was already very good in A1.
         
The Yggy via coax digital from an Esoteric UX-3Pi sounds very very close to the Esoteric playing a CD. It’s THAT good. Feeding the Yggdrasil via AES/EBU or USB is better than coax on my DAC. 
        
I thought perhaps you were thinking there’s something wrong with your used Yggy which is why I suggested the alternative of ordering the same configuration from the factory to compare. My bad.
I do not believe an A2 upgrade is going to fix what you dislike about the Yggy based on comments in your original post.

Good luck!
Thanks, I was hearing different things like the bass improved notably in A2, and other aspects. This is a real trickster. I have read so many similar and different opinions about the A1 and A2 but not many from both A1 to A2 owners.

My Yggdrasil sounds nothing like you describe. It’s a very fine sounding DAC. Very lively and dynamic, with good bass. 

I had an original A1, and then upgraded to A2. Both sounding similar, but the A2 is more refined. The bass is not significantly different between the two.

Perhaps the  DAC might not match up well with your amplifier? I see you’re going straight from the DAC into your amp. Have you tried an active preamp?


Good questions from @mooglie:
Perhaps the  DAC might not match up well with your amplifier? I see you’re going straight from the DAC into your amp. Have you tried an active preamp?


 I assume you have the volume control option installed on your Assemblage ST300B amplifier?

What speakers are you using? The 8wpc Assemblage ST300B requires high efficiency, high impedance loudspeakers to sound correct.
The amp mates up very well with everything I have put to it directly. And yes it has the volume control option. It is also heavily modded with the best parts. In fact I had an Ayre K-1XE preamp before, it was more transparent and better sounding without the Ayre. I have tried lots of combos. Had lots of gear, and lots of experience building and repairing electronics. 
I have Martin Logan Monolith 3 speakers, they have no problem with electrostatics, 8 watts is pretty loud. My TTW Gem 2 turntable, ZYX Fuji Gold cartridge, Manley Chinook phono pre combo direct to amp sound really good and have much more bass and mids even at low volumes where the Yggy I find is very weak. You have to really play the Yggy loud to feel like the bass is going to low powerful levels.
Martin Logan Monolith III loudspeakers (89db/4 ohm) mated with an 8 wpc SET amp is an interesting choice.

Martin Logan recommends minimum amplifier wattage of 20 wpc.

Have you decided what to do with/about the Yggy?



Yeah thats what they say but it works it just fine. What about when you feed almost no signal to your speakers, or no volume? isnt that no wattage? They are just stating what  they believe would be a good all around minimum to work a variety of gear to get to a certain db of listening volume.  
Copy that!

You should have no problem selling the Yggdrasil provided it’s functioning correctly, but with your deep experience building and repairing electronics you probably have that already figured out.

Good luck with your decision.

The Yggdrasil might have a problem driving your amp directly without a preamp. The stereophile measurements showed the Yggdrasil had a much harder time driving a 600 ohm load vs 100k ohm load. 
@ hsw 
Very interesting, that might explain the rather lack of power behind musical images that you are used being bone shaking and very authoritative. I recall when modding the amp I actually increased the input resistance to 1k. I’ll have to speak with Chris Johnson at Parts Connexion about this.
Thx! so far you have made the most sensible comment. 600 ohms is low and allows for a lot to current to ground.
now that I’ve using the unused USB for about 40 hours the bass is getting better but the impact is still to be desired. Much appreciated!
@dcrec, I’m surprised that with your experience building and repairing electronics you hadn’t factored Yggdrasil/Assemblage ST300B impedance match considering the Yggy is going direct to the amplifier.

@hsw, good thought. Hopefully it provides a clearer understanding of the underlying cause of the OP's concerns about the Yggdrasil, and offers a path to the solution.
@tvad
Really, thats what you are gonna do, ride some elses coat tales and make pokes at me for some reason? If you were so smart why didnt you say so. Its not the first thing that comes to mind of all the potential things that can cause any type of issue. There way more things that can cause this before impendence matching will.
Considering the amp has never had a problem mating up with anything it wasn’t high on the radar.
You seem to act like a know it all and comment for the sake of commenting whether it helps or not.
Please refrain from commenting in this thread, Im tired of your comments.
@tvad 
I stayed off forums for years just because of members like you, the moment someone had a comment thats bettered yours you swoop in and make a comment towards me in an insultive manner and then pat "hsw" on the back. What kind of childish behavior is this? You certainly arent sticking to the forum topic. 

@dcrec, you started a thread complaining emphatically about the Yggdrasil’s poor sound in your system and essentially suggested that the DAC is either faulty or just not as good as people say.                   
I responded because I have exactly the experience you requested in the first sentence of your opening post.

Much of this thread could have been shortened had your first post described your equipment and signal chain in more detail.

Perhaps it’s time to consider that the problem was never with the Yggdrasil DAC.
Your ignoring the point I am making, thanks for insulting me. Instead you try to blame my approach to the issue at hand. I never stated the DAC was faulty, nor did I assume it was. I heard many different things from many different sources so I am trying to get a simple A1-A2 comparison but thats impossible obviously.  Youre a real piece of work. Why would you comment on a comment with a negative at me  , and then comment on another comment with a positive that has nothing to do with you or the thread. I Suggest unless you have anything to offer about the Yggy, A1-A2, then stop harassing me. You don't know the process Ive gone through, combinations Ive tried,Cables, etc, etc. Nor did I ever want to offer that. I only asked for A1`-A2 COMPARISON!!!!  But you want this thread the way you do.
I wrote these words: I was hoping some of you members had done the upgrade to A2 and had some A1 to A2 experience you would like to share.

Your words:

Hey just my 2c but I owned analog 1 and 2 Yggy and they both sounded identical to me. I actually downgraded to an (a2) gungnir multibit because I just could not tell the difference.

i consider myself pretty good hearing, being a trained classically in music theory. Have played many instruments in bands and know what sounds accurate.

i honestly could never find much of a difference at all between the differrnt multibit dac offerings by schiit. I suspect they all have an almost identical  sound signature and any wild variations or deviations from linear sound that many members on online forums report is simply explained away to confirmation bias.
My suggestion to you is to get a new dac. 
@dcrec, my first post in this thread on March 3 directly answered your question regarding first hand experience with the Yggdrasil A1 and A2 boards.
This quote from your original post sounds like you think something is faulty with your Yggdrasil DAC (and the company, and the designer of the DAC).

”I sort of feel I am at a point of selling or upgrading. Heard so many good things but now that i have it Im not sure an upgrade will fix all the Schiit that Schiit screwed up on in the first design. Its also annoying paying for upgrades that essentially are design flaws.”

Why not simply add a preamp to fix the impedance mismatch caused by going direct to your amplifier?
