My R2R 11 has labels on the switches

 

[conquerator2]

Mine doesn't either. Makes no difference

Mine is labelled, purchased a week ago directly in Yuan from China. Though i prefer unlabelled.

Just get the R2R 11. I think after 54 pages it's pretty clear that the majority of this thread prefers the R2R 11.

EDIT: A vote between the NFB and R2R should be added to this thread.

Have not you made up your mind after all these months? Buy R2R 11 right now for your AKG K712 Pro and be happy, but NFB 11.28 emphasizes speed while R2R 11 does not emphasize anything, and that will be good for EDM, but I still do not know which of the two is best for signatures in the form of V.

Just put the Schiit Eitr in the chain with the R2R and I’ll be damned...the Schiit works! It actually does sound clearer. I gotta say I was a bit skeptical but alas, I was wrong.

Thats interesting! My R2R 11 probably gets a lot of jitter from my laptop.
What are other devices to make sound cleaner? I heard about Audioquest Jitterbug only.

Everything makes a difference!
Probably Kingwa discovered that the white labels color the sound a bit and removed them to achieve better clarity.
So you may even be lucky with the pure switches.

oh no then we all have the "old" version without the labels

I recently purchase an iFi Micro USB3.0 USB power conditioner/signal re-constructor and although it is quite expensive at $399 the improvement it has given me is too great for me to return it. It feels like I bought a new DAC. I was skeptical at first, but after listening I am impressed.

That's too expencive for a signal decrapificator.
Jitterbug is $75 at my local store, is it worth it?

Never used one, but if they have a decent return policy, maybe you can try it out and return it if you are unhappy.

You should get a small improvment. For 99$, get a Schiit Wyrd instead. Or better, a Schiit Eitr for 180.

Thank you!
I don't know if I want to spend another $179 for the LED lol

Someone suggested trying a powered usb hub so I will let you guys know the result

I have been using iTunes and VLC. I will try that software too

Based on the soundfile posted earlier, the buzzing sound has nothing to do with the software used. If unplugging your keyboard solved the issue, then that's narrowing it down to the keyboard as the source of the problem.

I'd like to hear back from you if turning off the LED's (FN + F6 by default I believe) solves the problem or not.

I didn't notice any buzzing through the AT AD700x's on a PC with the K-type connected, but I could hear a hum from the keyboard itself when the lights were on.

I like iFi AUDIO iDefender3.0 better, the effect is a little more noticeable.
I use it without feeding it with external power - strangely it sounds better to me this way.
The effect from what I have read depends on your PC/laptop, ground loops, etc. and can vary for different users.
I had the JitterBug and sold it. Should be roughly the same price.

I feel the R2R11 is indeed (as also noted by others) less sensitive to jitter than other DACs I have tried.
With R2R11 the difference between SPDIF out of Digione or Singxer F1 and USB filtered trough iSilencer and nano iUSB 3.0 are less obvious, almost non-existent (not the case with Marantz HD-DAC1).
Also the difference between filtered USB signal and straight USB from the laptop while still noticeable is smaller.
This is good news as you don't need to invest a lot in decrapifiers to enjoy good sound.

Now I have not tried Eitr as people here seem to hear nice improvement from it. The effects of JitterBug / iDefender should be smaller.

If the led is off then the buzz goes away even when the k type keyboard is plugged in.
