you make it sound somewhat more simple than it really is.....
The Devil, as usual, is in the details. I would suspect that a good implementation of a middle of the road chipset is better than a mediocre design using a top-line chipset.
That being said, it is probably easier to do today with such highly integrated chipsets available. Just reading over the Wolfson datasheet tells me quite a bit about just how many options you can use or NOT use when using a WM8740 chipset as say....the CA DACMagic +. They could have used a single chip, but chose the more difficult path of dual differential using a pair.
Read thru the attached link to the Wolfson WM8740 and see the options and though that went into this chipset. I have NO idea where in the line this chip falls or how it compares to others in the Wolfson line or other manufactuers stuff. Also, given the OTHER parts of the design from what would appear to be a simple capacitor or resistor choice to whose filters to use and of what type, and you can clearly see the issues.
It's all about choices and expected price point.
I would expect that a 'perfect DAC made for 1000$' to sell for 4x or 5x that price. Certainly not a budget component except to one wih pretty deep pockets.
If you meant SELL for 1000$, I would expect total manufacturing cost to be no more than 250$ in larger quantities. I'm sure the CA offering is near this level.
It is also true that as 'the state of the art' improves and the knowlege base grows, such designs DO get easier and better for less $$.
Too much is never enough
