Audio GD NFB-11.28 vs R2R 11
Dec 3, 2017 at 11:57 AM Post #316 of 2,569
Hey man. I ordered R2R 11, which is pretty much different sound interpretation of nfb 11, with tcxo upgrade already on it.

Paid 378 for it including shipping. So if you like more analytical, nfb11. More musical r2r11. For about 15 dollar difference.
Right on, thanks. I'm kinda hoping the jumpers on the nfb11 to a warmer sound will be noticeable if I want something different, and yes im still torn between both these guys! Will be powering the hd6xx cans and the LCD2 Classic Audeze.

I've had my unit now for a little over a week and I have yet to hear the popping mentioned in other threads. I mostly listen to Spotify and YouTube. I haven't listened to some private stock which I'm sure was different b/r then Spotify and still.... no popping.
which version do you have? sabre or r2r?

ESS will have more detail (11.28), the R2R-11 is made for people who like oldschool stereo sound over high level detail.
I"m reading through this whole thread laughing at the "I don't feel pretty anymore" comments when THIS ^^ happens...thank you, you saved this thread! You explained the differences in layman terms and I THANK YOU FOR THAT, :)

I don’t think they are the same. My guess is, that R2R 15 was the first attempt to build a NOS R2R/Multibit DAC in this price range, possibly encouraged by Magna (since they are the only ones who sell it). Then the DA-8 boards were ready (and replaced DA-7 further up the range), and it was decided to apply them to the budget DAC as well, which then became R2R 11. So, my guess is R2R 11 is worth the extra outlay, but again, I’m just guessing.

EDIT: Found R2R 15 on Audio-gd's chinese site version. Maybe it was/is primarily intended for domestic sale.

the amplifier is pratically the same, confirmed by the shop. same power output, etc. the only difference is the dac.
in any case saved some money. and the dac is good but limited to 16 bit

Does anyone know if these units are good for sensitive / low impedance IEMs such as Andros and the sort?

I'm wondering if the noise floor would be low enough, or are these better suited to normal headphones.

IEMs sound great on the R2R 11: I've listened to Massdrop x NuForce EDCs (16 ohm impedance), VSD3s (40 ohm impedance), and GR07s (51 ohm impedance). The headphone output impedance on the R2R 11 is 2 ohm, so I'm assuming most IEMs would be okay.

EDIT: I generally kept the volume knob around 8 o'clock when listening to IEMs

Thanks, I spoke to them about it. I have ordered a custom version with 0dB gain and high gain (+12dB?) of the R2R11.

Should be great for my Andros and Spartans and higher gain should handle my Sennheisers.

Congrats - I'm sure you'll enjoy your IEMs on the R2R 11 :gs1000smile:
(btw, I think the standard configuration is low gain = 0 db and high gain = +12 db)

Hey guys, has anyone here tried the R2R 11 paired with HD800's? I should be getting my R2R 11 today, but am just curious if someone has tried this pairing and what your impressions are. Thanks so much for the discussion here you definitely convinced me to give this unit a try!
