Just got a Yggdrasil!

[Speed Racer]

Multibit....not single-bit.

 

Once you get your Yggdrasil burned-in, it only take about 48 hours to get it to a thermally stable state from cold.

Electronics of that type don't "burn-in" as in improving performance. Burn-in is only to weed out units that fail due to "infant mortality", The DAC does need to thermally stabilize, however. Even Mike Moffat says that. 

 

Well, there are plenty of people out there, including me from personal experience with my Yggdrasil, that would disagree with you!

The Yggdrasil's AD5791BRUZ is low resolution but very accurate DAC chip.

 

I am pretty sure that the AD5791 is considered a high resolution DAC chip.

What DACs have higher resolution than 21 bits? All the math is done at 32 bits and rounded down to 21 bits just before it is sent to the DAC chip.

[Speed Racer]

How many DACs out there have 32 bits of resolution (ENOB)? I am not talking 32 bit math here....

It's rounded to 24 bits if at all.  21 bits has to do with dynamic range above the noise floor, not internal math.  21 bits is starting to get down into the thermal noise of the equipment.

 

Mike said, over on Head-Fi, said "DSP processor in all Schiit multibit gear is 32 bit, waaaaaay overkill". He went on to say that, for the 16-bit DACs,  "the data is rounded to 16 bits" before being sent to the DAC chip. Based on comments over on SBAF made by by Jason Stoddard, they round to 21 bits in Yggdrasil. This was in response to a discussion regarding comments made by John Atkinson of Stereo Review in regards to Yggdrasil an truncating to 21 bits. Jason said they rounded, not truncated.

[Speed Racer]

Yes, PCM is so horrible......

[Speed Racer]

I wrote to Nick at Schiit Audio and asked him about this. He told me that Mike said that they round down to 20 bits before they pass the data to the DAC chip.

Thanks, 21 just sounded odd to me.

 

(OK, really bad pun there....)

 

So, my question is how can you claim 21 bits of resolution when you only use 20 bits of data?

[Speed Racer]

Comments? It's an 18 bit DAC chip.

So you believe in both cases (yggy and gungnir) Schiit is overstating the theoretical resolution by 1?

 

 

No, I don't. They use two per channel. I just don't understand the tech behind how they do it. Which is why I am asking for an explanation.

[Speed Racer]

Mike came back and told me this:

 

"Two phase halves summed yield an extra 6 db (1 Bit) of resolution."

 

So there is the 21st bit for Yggy and the 19th bit for Gumby!

The MSB V Diamond can do 26-bit for example.

 

I have to laugh. You realize that is an SNR of 158.28.....if you believe that number, I have a bridge I well sell you, cheap!

I had not previously heard about this. Is anyone aware of what John Atkinson was exactly referring to when he called the Yggdrasil "obsolete"? I have significant respect for John, and his ears, but that's a ludicrous statement at best. And please tell me it wasn't associated with lacking MQA compatability because that would deserve a term beyond ludicrous.

 

Mr. Atkinson either had a bad day or has it out for Schiit Audio. I hear it is the later. I also don't think he really understands the subject matter.

The balanced setup contributes 6 db == 1 bit of dynamic range. 

 

Look at 7 posts up......

I mentioned the Yggy's zero-crossing glitching a while ago. And I personally didn't like the way it sounded compared to my regular DAC - I still have the digital captures of the Yggy's analogue output that clearly demonstrate that the Yggy changes the sound of the original files in a way that my regular DAC doesn't.

 

JA's measurements weren't very complimentary either. He finished his review with this:

 

 

 

 

[Highlights mine.]

 

My feeling was that these shortcomings were indeed audible. But many (most?) Yggy owners love the way it sounds...

 

Mani.

 

Not this crap again........now that I have an Yggdrasil I think you are more full of it than before. You, like JA, must have something against Schiit Audio.

What parts of my post were crap?

 

That the Yggy has zero-crossing glitching distortion?

That I personally didn't like the sound of the Yggy when I had it here for a few weeks?

That the Yggy has problems with high level, high frequency tones?

That the Yggy has problems with the LSBs of 24-bit data?

 

You don't have to get all upset just because my opinion of the Yggy is different to yours.

 

Mani.

 

I see one thing on that list that is right. That you don't like the sound of an Yggy.

[Speed Racer]

Put a certain user on ignore.....what a waste of bits.

[Speed Racer]

I saw this guy's post about Yggy before I ever thought I would spend $2300 on a DAC and well before I joined here. I thought his conclusions were ridiculous then as much as I do now. Especially that "filter" he had his buddy do that "Proved" the glitch could be heard.

[Speed Racer]

That person even gave this post a negative:

Too funny but not surprising.....

Considering the 7K MSB Analog is clearly superior to the Yggdrasil, it's surprising to hear that the Diamond V performs so poorly.

Well I don't hate Schiit. I've auditioned most of their amps, found most of them lacking -- but I currently own the Mjolnir 2. I haven't tried their multibit products, but I am meaning to.

 

How can you say the MSB Analog is "clearly superior" to Yggdrasil when you haven't tried any of the Schiit Audio multibit DACs? I am not saying it's not because I have haven't tried out any of the MSB products. It just seems odd to make bold statements like that without any personal experience. How you tried out the MSB Analog or you just going by specs and prices?

That's based on a detailed review of the Yggdrasil which compared it to the Analog.

 

To paraphrase, the Yggdrasil with the Hydra Z bridge plus power supply brought it somewhat close to the Analog. The Analog with the latest updated Quad USB module put the Analog way out ahead.

 

So your definitive statement is based on random reviews and not personal experience. Got it. Now I know how much weight to put on your statements regarding Yggdrasil.

You put facts and evidence forward for your point of view on something and instead of counter-argument, they come back with name-calling and ad hominem attacks.

 

Crazy world!

 

Funny, I haven't seen any name calling or ad hominem attacks here. They do call you names over on SBAF though!

 

All I see here is people not agreeing with your positions, methods, and conclusions. I alway find it humorous when people conflate disagreement and challenges with name calling and ad hominem attacks.

[Speed Racer]

We know that they round off to 20 bits. They do not truncate. We also know they get an effective 21 bits of resolution because they use 2 DAC chips (4 when using balanced mode).
