Audio-Gd Master 7 - Discrete Fully Balanced DAC (PCM1704) - Page 52

post #766 of 2253

Purrin: Thanks for the overview. That is tempting me to get an OR5 now. 

 

I had a similar experience with the Resonessence Invicta: It is a more precise DAC overall, but doesn't seem to have the overall listenability of the M7.

I posed a version of your question to Audio gd and got the following reply from Kingwa:

 

"The NOS-1704 have slight different sound to the SA1 even it setting at any modes. The NOS 1704 have a bit smooth sound than the SA1."

 

I'm a bit confused here: NOS DACs can accept high bit rates unless there is a limit in the S/PDIF or other inputs. Maybe he is using the DIR9001 in it? I wonder if it can be ordered with the WM8805 instead for 192k. I might have to ask him.

I love my SA-1.32 but really should try and get the scratch together soon as well for the SA-2 before it goes away!

Interesting...slightly different, a bit smoother than the SA-1 even when SA-1 is running in NOS or other mode (right?) Thanks for sharing that response.

I tend to prefer the SA-1 in 8x mode more than NOS anyhow. It would be interesting to hear the new NOS only version. I use the USB-32 input though so this one's kinda not ideal for myself but it's exciting to see a new SA DAC. I'll stay the course for a SA-2.

That's certainly a DIR9001 module in the pics, so that would be limiting it to 96K. I suspect you are right that the WM8005 could be swapped in because it looks like the plugs, etc are identical to SA-1 where it can be swapped.

With the SA-1 the DIR9001 was much better for me. In contrast, I found the WM8805 ok with the NFB-10SE.

Seems like a SA-1 deprived of its DSP upsampler.

 

Apparently, Kingwa is anticipating a shortage of PCM1704UK chips... I should hurry up and get that SA-2! If only I had the dough for it...

Would this translate over as delays in M7s as well?

Purrin: Can you post more details of the OR5 I2S set-up with the M7, e.g.: What cable it being used to connect it?

 

Someone started a new thread for the NOS-1704, so I've moved my discussion of 192k support there:

WM8805 seems to work with all other current Audio gd PCM1704UK dacs - including an SA-1 I use

That's because there's a DSP oversampling and sending the output in the format required for the PCM1704. The NOS-1704 doesn't have a DSP as far as I can see.

I looked up the pin-outs for the singled-ended i2s spec for AGD and Empirical Audio and terminated my own CAT-6 RJ-48. It should have worked until Soup told me that Prepo had already asked AGD to arrange the input pins of the i2s to the Empirical Audio spec. So I just used a regular CAT6 cable, no rearranging of pins necessary. 

 

With the standard AGD i2s arrangement, this is how it should go with the OR5:

 

 

 

You can probably ask Steve or Kingwa to make a cable for you.

 

P.S.

 

Rubenpp just sent me a hyperclocked OR5 with regulator upgrade for i2s. My unit only has the regulator upgrade for i2s. No hyperclock. Will get back to you on the results. Be prepared to burn money if you go down this route.

Audio-GD just released the NOS-1704 which should be the last PCM-1704UK based product before this DAC stock last, and this also indicates that the production of Master 7 is coming to end. Hurry up if any wanted to get one from Kingwa.

Thanks Purrin. The internal I2S cable is easy to reconfigure so if I decide to go crazy with an OR5 I can.

Only while stocks have depleted right? I'm sure he'll buy more 1704s due to the relative popularity of those corresponding products?

Bah. I've heard that line from AGD before. If it's true, and I don't get Master 7 in time, the Schiit Yggdrasil is always an option. I trust Mike Moffat of Theta yore.

The price of the PCM1704 chips is the point.

Before TI  advice the new customers don't applied the PCM1704 chips, we know they want to discontinued the chips and price must increase.

So we have the stock on old price.

Now the new price is unacceptable.

post #779 of 2253

I guess I better order mine fast. Kingwa, what is the best way to order?

post #780 of 2253

Dont wait. Just drop them a mail, let them know your intentions and where to ship. that's it.
