Audio GD NFB-11.28 vs R2R 11
Apr 19, 2018 at 5:34 AM Post #1,276 of 2,569
When I set my optical output to 24bit 96000hz I get a horrible screeching noise but it says the R2R-11 should support it.

I use the following cable if it matters: https://www.amazon.com/BlueRigger-Digital-Optical-Audio-Toslink/dp/B005LJQMZC

And the optical out from my EVGA Z97 FTW motherboard: https://www.evga.com/articles/00835/

any ideas why?
I would contact Kingwa via email ,you shouldn't have any problems at that rate
Cheers

Do you have other devices connected through the other inputs? If so, try turning them off. Disconnect the usb if connected to the same computer. Try other rates and another source, like a dvd player.

Also, your optical out has to be configured to output 2-channel pcm. It is perhaps set up to ouput a home theater format.

I'm not a windows expert, but I guess the Amanero Digital output should be the dedicated playback device.

I'm not using USB I'm using the optical port.

I have the optical out running on 2 channel 24bit 96000hz. 2 channel 24bit 4800/44100 work fine. Only get this noise with 96000hz which I would like to use for my 96000hz FLAC music.

Well. Could be that your optical out is too noisy or jittery. Or a defect.

Toslink must not support beyond 96/24, not stated formally but it's almost universal with dacs.

maximum optical sampling rate is 192kHz all tho R2R 11 can only swing 96kHz
Optical model: 44.1kHz, 48kHz, 88.2kHz, 96kHz

Thank you the replies, you are correct R2R 11 optical accepts 96 kHz max.

I'm on W7x64 and have only two supported formats checked, 96 and 192kHz,all working great ,R2R 11 sounds great via optical as well ,I would say about 50~60% of my Flack music is 24/96kHz or less so optical is great option to have ..very smooth and some might say that it sounds livelier then via USB
Cheers

I have bought a usb cable from AudioQuest (Pearl) a couple of weeks ago, didn't expect anything of it because I never thought a usb cable can make the sound better.
But I've heard a little better bass control and a bit more details in high freqs. And continue to hear that on all my well-known tracks with both of my pairs of headphones.

Maybe the blue stock cable that comes with R2R 11 is just made of shiit, I don't know. I still do not believe in massive imrovements of using an expensive usb cable vs a decent but fairly cheap one.

So it turns out I have the latest firmware on my R2R11 because it got shipped March 30th.

I do not hear any audible pops in foobar when switching between different FLAC songs (44100, 48000, 96000, 192000 different formats).

I still do hear very faint popping sounds when watching YouTube videos/twitch streams or playing games.

I am curious, how many of you guys are using AudioGD with headphones ? My r2r7 sounds bass head level in comparison to lks004 DAC. Yeah, I know burn in, but I have never seen burn-in that transform bass head level into dead neutral, and the people who claim r2r7 is neutral are using speakers while I have Stax SR009

Don’t mention about cables, because everything I have is Solid-Silver, even the Powercord for my system. So, let’s talk about sound signatures. Is audio GD known for basshead house sound ?

I do. I have a pair of he560. I get the same signature using the hifiman cable as i do with speakers.

It's the nature of this dac. The number of matched transistor pairs is big and they do not break-in at synchronously. Same for the precision resistors. There are over 350 per board (it is double-sided). I have never owned a component that changed so much during break-in, especially the first 300 hours, and it goes on beyond. The output stages needed 6 months to reached their full potential. At some point, you will hear it as neutral, then it will depart from neutrality and come back. Roller coaster effect.

I'm glad you mention this ,don't know about r2r7 but my R2R11 is the only SS I have ever tried that's not lacking in low end department-20Hz region is very well controlled on my LCD-2's and it makes them thump-ers ,almost physical low end on some tracks
I doubt the burn in will make a difference ..I hope not :)

The r2r 11 does not change very much with burn in. You get cleaner bass and a more detailed sound. Takes 2 weeks or so of continuous playback. I am in love with mine. I can't believe how good it sounds with everything. All genres are rendered extremely well, that amazes me. Tonal richness, and the textures you get are simply unbelievable at that piece point.
