Mike, I know this is long range, but DACLadder over on another thread spoke toward the advantages of using multiple DAC chips per channel for lower output impedence and quicker response.  Can you foresee a possible upgrade of the Yggy or similar product down the road along these lines?

Hm, Yggy may already do this?  Do we know?

Rechecking references, it appears that the Yggy uses 2 DAC chips per channel.  So I guess what I'm asking is whether 4 (quad) chips per channel will offer any signifcant advantage/improvement.

 

[cizx]

Maybe stop asking for upgrades to a device that isn't out yet, and for which specifications have not been officially published, from the guy who hasn't built it yet. Just a thought.

 

[jacal01]

Maybe one can allow Mike to contribute his thoughts on the subject, if he's so inclined, before imposing self-annointed censorship.  Just a thought.
 
He is somewhat of an authority.

My take on this is that two chips per channel matters (and seems to be pretty standard), while four seems overkill.  But that's just a guess.
 
What I want to know is 'does two chips make deglitching easier'?  The chip is (relatively) glitchy given its very high linearity specs and requires deglitching.  I could see that dual or quad chips making that easier.  Or maybe deglitching is so easy it doesn't matter, simple sample and hold, with a short enough and stable enough sample window.  So probably not...

There are papers on stuff like that.

  There are papers on stuff like that.

How do I find them?  Google doesn't differentiate enough given my level of knowledge.
 
The ironic thing here is that one of my cousins is married to a now former long-time DAC chip designer who now does VC, including audio (not hi-fi) related fundings if google is reliable.  But unmentionable family related reasons (not having to do with him or me) mean I can't talk to him.
 
Hm, maybe I should send him an email and let the family fallout happen...

Yggy NEWS !  
 
There's no News , thats the news !!  
 
These guys gotta set up the new Shop , get things sorted out , get some bills paid , buy some 10,000 sq.ft. worth of infrastructure , fixturing and more personnel , all of it running properly .  That Integrated is a complex piece that hasn't been durability proved yet .
  They may not get the BIG DAC out in the 1Q like Professor Mike suggested , it's easy for me to expect a 2Q or 3Q 2015 Release considering how complex their new Business has become .  They only have 6 Staff , they have Wives out in the shop doing stuff ( I'd dread having my Wife hanging around breaking her nails and getting dirty , there would be not one moments peace  )  .  Keep your fingers crossed that no major Calamity befalls our Hero .   I marvel at how well these guys are keeping the wheels from falling off .  
  Baldr's Big DAC is the most complex item they will be offering , the parts are gonna be costly so there's gonna be a large up-front cash outlay .  Lota-eggs in one basket with YGGY .

Yep.  Don't care how long this takes.  Gives me more time to save for it!
 
It's not like it's the "Schiit-Pulse" and we already ponied up the $$$ for it already...

 

[jacal01]

  There are papers on stuff like that.

 
No public papers per se, more like various informed opinions, generally biased toward particular DAC products.
 
Multiple parallel stacking of the Yggy DAC chip per each channel may be further complicated by its voltage output, instead of the additive current outputs argument.

Yep.  Mike is.  What you said, though, was essentially, "I heard about a thing.  Hey Mike!! MIKE!!  Have you heard about this thing, and when will you be changing your thing to implement the thing I heard?!?"

Yes. Paralleling DACs is nothing new. I'm fairly sure Mike already knows about this technique!

If he decides not to parallel two DACs, or chooses to use 2 per channel or 8 per channel, he will have good reasons (cost, heat, timing issues etc).

But how about it Mike ? However many DACs you now use, would you consider doubling them? If you quad them, you have an almost guaranteed sale ...
