Audio-Gd Master 7 - Discrete Fully Balanced DAC (PCM1704) - Page 79

post #1171 of 3589
First I am sorry to here about the trouble . And what your saying is leave the 200 ohms resisters alone. So I will then. . What is odd over this is . Kingwa said it is terminated at 75 ohm. But when you looked at board it sis 200 ohms. And beyond that is Steve at imperical says it's best to be terminated at 75 ohms. Wow what to do. I did use the offramp with the rj45 input and it did greatly improve the Mm7. I will what you asked for a pages back reg the PSU.

Thanks

Al I think I would just leave it alone.  The I2S termination resistors need to be at the end of the line anyway for best performance.  You have the cable that Empirical states is optimal length.  So enjoy as is.  It will never be perfect.

 

After studying the HDMI interface and the LVDS chip technology used I feel that it is superior to the RJ45 port.  I could improve RJ45 signal qualify with terminations and cable length but sound was never really consistent.  Bench testing HDMI looks very promising for signal quality but no guarantee how it will sound.  But the HDMI retrofit is not plug and play and I have to find a source inside the M7 for +3.3V to power the receiver chip.  If I ever get the Off Ramp repaired I will try again carefully. 

 

In the meantime the new USB32 2014 firmware/ drivers sound better IMO than the year old firmware/ driver.  I listened to the old firmware/ drivers for many hours prior to upgrade.  Yes I can tell a difference.  Less grain, more open, wider stage.  But what is up with 192kHz playback (no sound)!  I haven't heard a reply from Kingwa.  But soundwise a big step in the right direction!

As for the USB over the rj45 I will try to test and compare
Now hdmi I agree. I use itbwithbrhebps audio pwd mkii
Wow it is a very different DAC I guess in part to the better
Hdmi. Also the outputs all work at the same time
How. Is that done ??

You talking about the Off Ramp outputs all active at once?    There are separate buffer/ drivers for each output.  The Off Ramp USB board supplies signals to all four outputs simultaneously whether used or not.

Hello,

 

Where did you find the new firmware ?

Home page of audio-gd. A link is up there.

The same here with the 192kHz playback but we are not alone. Check the following thread: http://www.head-fi.org/t/638252/audio-gd-usb-32-firmware-drivers-and-feedback-thread/105 

One guy found a solution: Do not use USB3 ports but try a USB2. I haven't tried it yet.

post #1178 of 3589

Thanks for the USB32 link.  All of my USB ports are USB2.  Probably a simple bug in the code.

Hello,

 

I upgraded to new firmware / driver but I can't control the volume from my computer anymore and I don't have the control panel to change the sampling.

post #1180 of 3589

Ok i downgraded to 9-3 firmware and it works fine. Can I try the firmware 11 ?

 

I noticed with the 9-3 more transparency, less forward, better bass control. I think my previous firmware was very old. 

post #1181 of 3589
Dac ladder what is your setup ? Headphones list please and if speakers too list please

post #1182 of 3589

FW #11 is for DIV3 as far as I know. The #9 and #9-3 are the latest ones ( except for 2014 ) for the Master 7 ( or any other DAC integrating the USB32 )

post #1183 of 3589

Hi guys!

 

I have a problem I hope you can give your opinions. I got Stello U3 connected to input 3 spdif in Master7. When 192khz sample rate is selected (KS/ASIO) some strange pops turn up even when playback is stopped. Any idea would be appreciated.

 

Kind regards,

JM

I think DAC is faulty...I have changed pc, transport and cable and it happens the same

post #1185 of 3589
Do other inputs work ok. And try all resutions too. It could be corrupt sofetware.
