Best way is to ask the source: @Kingwa
Actually, I did ask him via email:
- Told him I already owned 2 Audio GD DACs in which the ACSS output has been converted to RCA at slight extra cost (so that each DAC has 2 X RCA output pairs)
- Told him I was interested in an R2R 1 w/the same modification (coversion of ACSS to RCA is offered on the R2R 1, just as on the DAC-19/NOS 19)
- Asked him, given that mod being done--could all 3 outputs be used simultaneously (2 X RCA; 1 X 3-pin XLR pair) ?
- His answer:
"Yes, the R2R1 can change the ACSS to RCA , and output in same time with XLR.

@Pharmaboy that sounds like a smart thing to do, it still is a big amount of money you are dealing with.

Yes, it is. And I don't literally "need" a new DAC...I love the 2 Audio GD DACs I have, especially the NOS 19; and I've proven to my own satisfaction that both these DACs can output RCA signal to 2 different headphone amps simultaneously w/zero degradation.
My real impulse for getting the R2R 1 is two-fold:
- See how Audio GD/Kingwa is improving & evolving the NOS sound, using field programmable gate arrays + chips of his own design; and
- Get a 3rd live output (the XLR output)

"sorry about your wallet" you know
Let us know how it turns out. My own feeling tells me it shouldn't be a problem at all, acss is just different form rca and xlr outputs.

Just tried xlr and rca, skipped acss connection. Xlr and rca work fine together. I would just be guessing what adding the second rca inputs would do. Mr. Kingwa would know.

Awesome! Thanks for testing it...I feel relieved.
Hello guys. Maybe somebody would help me. I'm currently changing my audio-gd nfb-2 DAC. And there is question which one would be a better option:
-Audio-gd R2R 1 (I can borrow this one for test in my setup)
-Chord 2qute (this one I have no option to borrow for tests)
I can have both for almost the same price (brand new). My current headphone amp is audio-gd NFB-1 amp, using it with hifiman he560 trough xlr connection
Maybe someone could compare these two dacs.

Hi guys, I currently run an AGD R2R-11 dac/amp but am considering stepping up to the R2R-1. Two quick questions:
1. Any pops or skips at the start of tracks or during sample rate changes? R2R-11 has these, although AGD has just released a firmware fix.
2. Any low-level noise during DSD playback? Again R2R-11 suffers from this on certain DSDs.
If I’m going to spend upward of $700 on a dac I want to make sure the above two issues are absent.
Thx in advance.

Kingwa has confirmed my R2R-1 will ship once it’s done burning in! I opted for the isolated USB port, 2nd pair of RCA outs, as well as the TCXO upgrade (not sure what this is but seems like a good idea...)
Yeah, I’m excited to get a real hi-fi balanced DAC.

Oh, yeah! This is the one I'm interested in...can't wait for your comments (eventually--burn-in of AGD DACs honestly takes 100s of hrs)
+1, with answers to my questions above
1. None. Playback has been instantaneous and smooth for me -- over Optical and USB alike.
2. Can't say, I have no DSD content to test this.
Thanks, that’s all I needed to know. Much appreciated.

Audio-gd R2R 1 or Chord Qutest? Just ordered, and I’ve heard it’s shipped *Yay!*, NFB-1AMP and now the thoughts of a better dac are setting in. I’ve been more than happy with my Chord Mojo, but with the balanced amp, a balanced resistor ladder sounds like just the ticket. But I love the Chord sound. Any thoughts on Audio-gd vs. Chord qualities for pleasure in listening with my LCD-3s?
