The signature is one of general neutrality with a touch of sweetness to the midrange and upper registers, and a distinctly 'pristine' quality/clarity to the sound. Overall presentation is open with a good sense of air but is neither lacking, nor carrying too much, tonal weight/density. The RDAC’s rendering is fluid, articulate, nuanced, and well balanced—capable of excellent top-end delicacy while simultaneously plumbing a tuneful, driving bassline and keeping vocals present and lucid.” Head-Fi.org, SuperBestAudioFriends.org, Headphone.com

CEE_TEE. Can you shed light on whether this group is the same folks who created the excellent Heron 5 amp? I ask because the website for airist and for that amp does not appear to be actively managed. I think we’d all benefit from knowing as much of the story as possible. Thanks!

Yes, the same designers were involved in the Heron 5 amp!

The midrange is liquid and free of congestion. The treble is on the softer side of things but has an effortless, clear quality to it, even if some of the overall details seem to not pop as much as they should. Unless you are opposed to this warmer tone and liquid but very slightly soft timbre, it should just flow with ease in listening. It also has a nice sense of swing and micro-dynamics to it. It’s nimble and grooves nicely despite its warmer, softer leanings. It’s never boring, veiled, or smothering.” SuperBestAudioFriends.org, InnerFidelity.com, Head-Fi.org

"liquid," "effortless," "timbre," "nimble," "smothering," "congestion," "warmer," "softer," "veiled,"........
If I took a shot for every audiofool term written in that "review," I'd be in the hospital.

Hi Everyone, Nice to hear some of you already have your RDAC and are enjoying it! DRIVER STUFF For Macs- RDAC should be found in Audio Output Devices as "USB Audio 2.0".  For Windows- I have a link to the driver here and we will work on a product page link...  Windows Driver download link: XMOS Windows Driver (30C8) 
https://drive.google.com/open?id=1c0gQ2GjEaqS3pC75QXym_Jf9Veu11IbN  Note: Windows 10 may not need a driver.

I am unable to use DoP nor native DSD on foobar 2000 with this driver. Is this a bug or expected?

Agreed, in exclusive mode. My comment was directed at shared mode only and not with respect to a difference in sound quality - only with respect to sharing. For example, I have a pair of Klipsch speakers driven off USB and in that situation I have to use the WASAPI driver, 1 instance for each speaker. ASIO cannot do that.

When I order from Germany, does it ship with an EU Power Plug and a 240v power supply?

No. You just need a plug adaptor and all shall be good.

I’m wanting to connect my iPhone X to the micro usb input to the R2R dac. I also have The Thx 789 amp. Will the iOS camera accessory be all I need

I called the CEOs of Google, Bing, DuckDuckGo and Baidu and asked this very question, because my own research, quick but thorough, came up empty. Each company formed a task group, concentrating on this very question. After a couple of hours they all came up with the same answer: I'd have to ask YOU, since they do not know why YOU need it. Joking aside, balanced output is needed mainly for two main reasons:
  1. You have a lengthy cable run and you want to minimize the amount of induced interference between two connected devices
  2. And/or your device with the balanced output is a truly differential design; meaning it has two discrete circuits for each channel (non-inverted and inverted).
With the latter you gain 3 dB better dynamic range, but the costs of designing and manufacturing rise up pretty quickly. And this works best in situations, where your whole audio chain is truly balanced. As Airist R-2R Dac is a cheap device (considering it has already a "proprietary" discrete design consisting of many individual components), it would be economically challenging to offer a truly differential design at this price. Then there are of course other reasons why you "need" a balanced output; maybe your active speakers or amplifier has a balanced input. Maybe it is even the only input it has! Then, it becomes a matter of convenience instead of using an active balancer or an RCA-XLR cable (wherever that is possible). But either way, we do not know it until you tell us.

I have had this DAC for a few weeks now. It is hooked to a Mac mini via USB. Has anyone experience the output choice, USB 2.0 Audio, disappearing occasionally when the computer is awaken from sleep? I tried restarting my computer, but it does not help. Turning the DAC on and off does not help. What brought it back was to unplug and replug the USB cable, then the choice returns. My Topping Dx7s does not do this. Any ideas? Otherwise, I do not have any complaints about this unit. It sounds great.

I don't have a Mac but I had to try several usb ports before my Windows 10 system recognized the DAC. So you might try a different port, not sure if usb 2.0 or 3.0 makes a difference. But it is rock solid now. I ended up using additional drivers, though I don't think it was necessary.

I know that ladder DACs are temperature sensitive and many people advocate leaving them on 24/7. Does anyone know if this is safe to do with the Airist or what the manual might say?

With a resistor array such as this, the exact temperature is not as important as the global temperature of the entire array(s). Leaving a device such as this on, and in a stable isothermal environment is the ideal; for exacting it's inherent top audio performance.

Does the power supply work with a simple adapter, or does it need a voltage stepper?

If you mean a different country plug adapter then yes that is all you need. The actual supplied power cord has a in built power transformer brick that accepts any voltage and sends out the correct voltage to the DAC.
