tempting, to get this cause i dont have any dacs currently other than the inbuild in Denon avr ...which headphone output sucks and my sennheiser hd650 have been sleeping it its original box few years

[@thisisdumbwhatthe]

@@johto Have a hunch that wouldn't be a good pairing (similar "sound signatures" that I think would likely exacerbate "Sennheiser veil" that many experience on the 650s).

[@ryanmccann2539]

I've got this running as an external DAC for my WIIM Pro into my Cambridge AXA35 and it is just velvety smooth.

[@Makaveli6103]

Just upgraded to this from my old iFi Micro iDSD Black Label. For the price this unit is so much better than what I had before.

[@thisisdumbwhatthe]

I was very disappointed with the Black Label. Way too hot treble in PCM causing me fatigue, and then became flat and dull when doing DSD (but that's also been my experience with every R2R DAC I've listened to so I won't be touching this either, although it is appealing for a budget DAC/amp, and doubly so since Schiit stopped the Magni Multibit option).

[@omeee]

@@thisisdumbwhatthe Black label was meh, the successor Signature is by far the best ifi product I have heard.

[@pk.002]

I have mine paired with a TA-22 that was tube rolled with Genalex Gold Lions. It's absolute bliss and blows away any previous dac/amp combo I had.

[@mich5528]

Why not use only the TA22? It also has an integrated dac, at least the Duo does I think. Sorry I am fairly new to this.😢 Edit: after watching the review, ok the fiio r2r needs to be the dac, got it now 😊

[@informedchoice2249]

If I want a cheap and cheerful option, this seems nice. I guess this with a FOSI Audio or similar? Your tube amp looks nice though.

[@pk.002]

@@mich5528 Good question. I did use it like that, but the ESS dac that's integrated sounds different compared to the R2R dac. It sounds more clinical, even with the tube flavoring that the TA-22 adds, whereas the K11 R2R is rich, full, and smooth all around. I would use something like a TA-26S OTL tube amplifier if I could, but as I use mostly planars and low impedance headphones, it wouldn't be a good option as OTL amplifiers are intended for high impedance headphones. The TA-22 being a hybrid amp handles everything from low to high impedance because of the solid state portion of the amp.

[@pk.002]

@@informedchoice2249 I have no experience with FOSI audio but a quick glance at their tube amps tells me that it would be a good match for the K11 R2R. I actually got the TA-22 as I wanted to use it as an all in one solution at first, but I paired the K11 R2R out of curiosity and the difference in sound is night and day compared to the stock ESS dac the TA-22 has.

[@pk.002]

@@informedchoice2249 The K11 R2R I think would pair well with a FOSI audio tube amp. And thanks! The TA-22 is phenomenal

Great review as always! I wonder how it compares to the SMSL RAW-MDA 1 though.

[@JohnSmith-oe4bw]

Short answer (I have both): The RAW is the best value AOI. You don't really need anything else. The Fiio R2R K11 sound is different. I'll give it that, but if you want fidelity, it does not compare to the RAW or other similar D/S dac/amps.

[@sam-f8v4y]

Hi, love your reviews! So passionate about the hobby, and it's nice to listen to your thoughts about them. One question, if the ef499 and this k11 r2r is priced the same, which one would be a better value buy? For context I'm using a Edition XS.

[@rotecrl9719]

urban legend has it that FIIO themselves only claim it to have about 72dB SINAD ( 1kHz ? what power? how would I know) So what one hears is most likely a good amount of lush noise and distortion and under all of that the R2R design may shine through a bit. Totally fine to like that! Just don't kid yourself that you can get an audibly transparent R2R DAC with that little hardware. Hopefully someone measures one of these soon and totally proves me wrong, because I want one. Especially at that price point, where it also doesn't feel as bad to buy an objectively subpar product compared to state-of-the-art. I just like that thing :-)

[@Panslapper]

No, stick with your Topping for gaming, it’s more detailed with a more pin point analytical sound quality and that’s a better quality for gaming. This is a music dac, smoother, warmer, less in your face, a more relaxed sound and not really for gaming. The R2R structure tends to be a little slower than its Delta Sigma counterpart, ESS, AKM, Cirrus Logic etc which tend to be more responsive, faster which is the kind of nature that compliments gaming needs more.

Everything is about a good power. Those small boxes just do NOT have room enough to place a good power source inside. I'm not talking about a main power line.

You can imagine how many voltage stabilizers (big correct capacitors, big heatsinks, etc) are in there... This is why 1100 R2R sounds better than 180 R2R. That's it. Because to select a better sounding window function is not big deal. To feed it with a clean and fulfilled voltage IS a big deal.

Regarding clean source - you have external zero noise ps for that.

@@trekkis But this is one for all: digital, analog, negative, positive.. It's not good and is only slightly better than a noisy PS.
