Audio-Gd Master 7 - Discrete Fully Balanced DAC (PCM1704) - Page 82

I don't notice any difference SQ-wise between the newest 2014 firmware and the first 2014 firmware.

Thanks for your observation.   I warmed up to V2 after several hours of listening yesterday morning.   Like you said V2 is certainly miles ahead of  the early 2013 version I had been running prior to V1.

 Don't know if you've noticed but the Master 7 is on pre-order now.

 Also the Reference 5.32 is sold out. 

post #1217 of 1921

Hope another alternative comes out like revamping the 7.32  or using another DAC chip. *crosses fingers*

 

Is there any other chip that's good for highend audio?

post #1218 of 1921
Dacs are in about three categories

1k and under
4k and under
And the ultra high end.
Now the first two use DAC chips off the shelf
And there is plenty to pick from as well as new and better
But most of the ultras used customized chips
Or some how alter there performance by hand picking.
Soy pint is there is plenty of other chips out there.

Wondering the same.   Stumbled across this DAC chip - ARDA AT1401.   Ladder R2R DAC with LSB trimming/ gain under SW control so instead of expensive laser trimming so it can be done on unit by unit basis at any time.  For instance, you could fine tune an assembled DAC box to compensate for not only the chip variations but all the other circuit components in that box.  Should make this chip cheaper than the laser trimmed PCM1704.  The AT1401 has large output current drive capability for great SNR so you should not need four chips per channel like in the Master 7.  Looks good on paper but how it sounds is another question.

At first it sounded horrible but I had forgotten to power down and restart the M7 after installing the firmware.  :redface:

I read that ARDATECH is dead and that google bought it. I'd have to put an external link to another forum though.

Anyone know what Metrum uses? I hate it when manufacturers scratch out the lettering on the chips. Really cheesy.

Google it
Somewhere it will tell you who

I thought that the Perfect Wave transport and DAC used a balanced I2S interconnection with signal circuitry, pinouts, etc. different from the OR5 and M7, so that some interface converter board would be required.  What am I missing?

No it's the same as the offramp. IRS a HDMI config. The offramp works great with it. In native.

Now the M7 is a rj45. Config. And the pin out is not the stock for the offramp. But the rj 45 cable or jack inside the M7 can be configured to work with it fine. As I a have both dacs and the offramp.

Since I have a PWT and M7, would the M7 jack reconfiguration be the better fix using a standard HDMI cable?  What is all involved with reconfiguring the M7 I2S input to HDMI?

post #1227 of 1921
No it will not work. It uses a different protocol. Pm dac ladder he is a pro at this . And truth is I get some of my info from him. And the empirical audio website forum. .
I have the transport too , the offramp is far superior to the transport. It looks great and works great , but it does not sound great.

Correct me if I'm wrong, but the OR5 converts USB input from a PC/server to I2S.  The PWT plays CDs.  That is the source of choice for me.

 

But you're saying that the I2S HDMI protocol used between the PWT and PWD will work for the OR5 HDMI to PWD2 connection, and the OR5 to M7 I2S connection via a RJ45 cable pinout conversion (?), but not a PWT to M7 connection using either an HDMI/RJ45 conversion or visa versa?

Yes , you are not the first to ask this question. And I am not an authority in this . But I do remeber someone asking and I think dac ladder answered this and he said no.

Yeah, I asked the question here previously back when of SoupRKnowva, and he responded that they were different modes of transportation, but couldn't offer up any details.  I just find it strange that the OR5 can work natively in HDMI I2S with the PWD, and the OR5 can work in I2S with the M7 via RJ45 cable pinout conversion, but the PWT HDMI I2S designed for the I/O inconnection with the PWD cannot work with the same M7 via an RJ45 cable conversion or other.   What changed?
