Mr.AtomicBob,
 
OooooooKay, finally we'll have a proper description and definition of the Bi Multi and the bigger one.  
 
I'll be hanging on every word and asking about the between the lines stuff.  
 
What you describe will probably be foundational for a great many folk's decisions.
 
I know of no person attempting this sort of thing and then accomplishing it. 
 
Someone of your stature, experience and background makes your tomorrow's work the 'Reporting Work' of the Digital year.
 
Big Sound tried but gave up ( I think they had easier fish to catch ).
 
I can also imagine all the World full of DAC reviewers following along with you, you'll probably set the Bar for the next generations of DAC reviews ( much like Harry Pearson did for HighEnd reviews ).
 
A proper lexicon of terms specific to DACs would be invaluable.
 
I've seen your work and the results of your work, if you can't do this no-body can.
 
Thanks for announcing this,
 
Tony in Michigan

  Last time was Project Sunrise III.

Bob, I would be interested in your one or two sentence impressions of the Project Sunrise III, if possible (if you have already reviewed it somewhere, please post a link, thanks).
 
If you think this is too off-topic, then PM me with it, thanks.

Look here for some comments on a particular system utilizing the PS-III for some listening experiments:

And here for another viewpoint with a different DAC prior to the Bimby:

  Have you taken a look at Van Alstine's ABX Comparator?  I've no idea if it does what you're looking for, but it's an interesting product and apparently one of very few that is focused on facilitating ABX testing.

Sounds like a fantastic use of $1k... or not...

Here's a link to AD8512 Data sheets if anyone is interested.

mmmmm datasheets.  [insert homer simpson drooling meme]

Teamwork!

how about a yawn? - specwise AD8510 looks hard to distinguish from a OPA134 - in fact I might prefer the system implications of 10x lower output Z of the OPA134 at 100kHz, Av 100 vs the AD8510 in the datasheet plots
 
which is only criticism of the datasheet drooling - I wouldn't comment on technical fitness without a application circuit diagram - and that would just be tentative, based on my estimate of the application requirements and candidate op amp specs
 
my shtick, such as it is, is designing composite multiloop amps for a circuit function - input and output op amps chosen to be good at their separate functions and used in a global feedback loop, in support of each other, can give large performance improvement over using a single op amp in many applications

Viewing datasheets is sort of like looking at new wheels in a catalog.  They might be pretty but they might not work well on your car.  It's all about the application...

There's nothing wrong with a nerd getting excited about reading technical stuff.

I guess AD think it's OK as they show the AD8512 in use for 4-Quadrant Multiplying Mode in the AD5547 datasheet

Has anyone here gone from the bifrost uber to the multibit, using the HD800? What would you say?
 
On a side note, does anyone think i am doing a disservice to my HD800 by using them with the Asgard 2?
