Balanced DAC's
fiogf49gjkf0d
I did not have time to read the articles carefully, but:

"The IDAT’s D/A conversion stage is also unique."

"In the IDAT, two DACs per channel are used for each half of the balanced data signal instead of one."

...the very idea of balancing DAC's is not so unique--enough to search e.g. diyaudio.com to see that
the subject has been well discussed (albeit only technically, of course, not much sound-wise).
I have my own plans to assembly such a DAC one day (but witout resolution doubling like Meitner).

Well...

Thanks, Romy.

Nice that the PF reviewer is so happy with his battery powered iDAT 44+. While I agree that it is a good DAC option, I have to add that we are still talking "digital".  With all problems of LPs and LP playback, IMO this is still the way to go, at least in terms of the "elements that make up Music", and the "resultant whole".  I would put HS, reel-to-reel "ahead" of LPs, but the entire tape thing is so fraught with problems - including extremely limited high-quality program - that it's become practically untenable.  As for streaming digital, what I have heard to date is not worthy of discussion in this context, despite the satisfaction derived from it by a given user.

Read and think more.

N-set,

In think you need keep reading as the balancing DAC is not something that make Bidat unique. I pretty sure 24 year back it was but not now. The whole idea of IDAT is (among many other things) that it dynamically applies type of digital algorithm (I think it is filtration type) based upon the length of signal. Pretend that that your short and laud notes are rendered by one DAC but your legatos are by another. I know it does not sound too good but whatever it is it does works. Please do not send to diyaudio.com. They can discuss whatever they want and frankly I am not so inelegant to understand their digital discussion. There are however some subjects that I do know and what I see the same diyaudio people do their “discussions” in there then I can testify they are morons.

I do not make any claim about IDAT, neither need I to. I just presented information.

1993!
fiogf49gjkf0d
Ok, I have not fully seen the temporal context, it was 1993!! Chapeau!

I did read about the algorithm, I just reacted to the claimes about the balanced DAC being "also unique",
which I quoted in the first line.
Now I understand, it was in its time. Diyaudio? Well, when it comes to technical things, I see
a lot of good knowledge and experience there. Probably they should not have the word "audio"
in the name of the community, as they do not deal with audio per se, though.
