after PCM1704 is gone, what about AudioGD?

easy: they are launching DAC's with ES9028, ES9038 and R2R DA M1 modules!

they look interesting and even affordable!

They are developing there own ladder dacs. It is called the DA-M1 module (I think)
Look at there new singularity 19 product. It uses these modules. Four of them

It needs an external power supply, right?

I have not heard it
The Singularity 19 is a complete dac including built in power supply. 120v input
The R2R module is like any chip and would be part of a complete dac which would have its own power supply

If I was in the market for another DAC right now, I'd be tempted to pick up one of Audio-gd's remaining Master 7 items, with 1704Ks.

I love the custom-built R2R movement. I'm less convinced about how everyone is consistently getting full 16 bit resolution from their solutions, let alone higher bit depths. Laser-trimming resistors on the scale required, and with the necessary, repeatable precision - even for custom levels of production - is not an easy business.

That's what makes DACs like the 1704 so special, from an engineering point of view, if you like their sound like I do. I wish them (all) good fortune and success, however!

If you could have only one, which which of the Audio-GD products would you choose?, posted on March 21, 2017 at 07:14:45

I have both the Master-7 and the Master-11, versions of about a year ago.

One for every room of the house?

the Master 7.

The only reason I didn't choose it a couple of years ago is that I was actually in the market for a transport, bought the Lite Audio LT-One and found the Lite Audio DAC 83 was pretty good in its own right.

It's still on my radar...

Does the Lite Audio DAC allow you to use it in NOS mode?, posted on March 22, 2017 at 07:56:46

Was considering the Lite Audio PCM1704 DAC as I have had really good luck the Lite Audio 'kit' 6SN7 line stage.

No, in that sense, the Audio-gd has an advantage in terms of choice of presentation. The DAC 83 sounds far from amusical, however.

One thing the Lite Transport does have - which I have found intriguing as the only other company I know of that has experimented with this is Audio Note UK - are an implementation of very small output transformers for some kind of digital signal conditioning. You can see them (at least I think that is them - two small black cubes) near the rear of the pcb, adjacent to the outputs. Commentary has been extremely hard to come by, save in Google 'Chinglish' - "RA audio grade buffer transformer for intact wave shape". They may just be part of the balanced circuitry, however. Just don't know.

The other thing, aside from I2S, that I liked in the DAC was the use of high quality output devices - the same ones used by Audio Innovations in their Alto amp (itself a homage to a Quad design, if I'm not mistaken). These produce a wonderfully full range sound of deep tonality.

[The encircled part is one which Lite Audio deliberately disguise. I'm guessing it relates to which particular filter they use for their unorthodox filtering arrangement - as discussed on a couple of HK experimental audio sites re the 1704K and upsampling techniques.]
