Digital-to-Analog Conversion: Dynamic Range: 129dB A-weighted • Max output level: +8dBu
 • Frequency response: 0-94kHz +0/-3dB, 0-87kHz +/- 0.1dB
 • THD+N: <-108dB @ +8dBu


Analog-to-Digital Conversion: THD+N: <-108dB @ +12dBu
 • Dynamic range: 123dB A-weighted
 • Maximum input levels: +12dBu
 • Frequency response: 20-80KHz +/- 1dB
 • Input Impedance: 4.76kΩ


Audio Clock: USB Sync Mode: Asynchronous
 • Sample rate Support: Up to 192kHz / 24-bit
 • Clock Type: Two discrete MEMS-based (Micro-Electro-Mechanical System) clocks
 • Typical .5ps (500 femtoseconds) RMS Phase Jitter
 • Total Stability: +/- 10PPM (first year of aging included)
 • 10 year aging: +/- 5PPM

It looks very intriguing. 1.5 W of power is a whole lot especially coming from something as small as that. I definitely want to know more about it.

These should sound fine, nice and honest, at least, seeing as they come from an audio engineering background. The DAC is probably over-spec'ed for the real world DNR/THD+N it delivers, and they probably could've swapped the pricier PCM1792A for the PCM1795A or even lower end model and still squeezed that claimed 108 dBA SNR out of the unit, but whatever, no harm in using a higher end DAC chip (only cost). Lots of marketing fudging with respect to "MEMS oscillators"... LOL... but hey, at least they're using discrete oscillators with low phase noise, or so it seems.

Only one thing I know that is MIYO use DAC chip as same as Cowon Plenue P1. They claim that they use audio-grade components and mount all of them on 6-layer circuit board likes Meridian Explorer.

Hey guys, this is Jon from H2 Designs, the company behind MIYO. Just wanted to let you know we're here to answer any questions you may have. With regards to how MIYO might compare to other products at its price point, we're working now on compiling real-world measurements, and meanwhile  have technical specs based on the specs of our components published here for now. I look forward to answering anything about MIYO you guys want to know.

Hi Jon, looking at the specs i guess it works via usb from pc only? Sorry im quite new to this portable dacs stuff. I usually juse just my dx90 :)

MIYO can work with mobile devices just fine, actually. It's not the primary use case we had in mind, but it does work so long as the mobile device is USB Audio Class compliant. This would include Android 5.0 (API level 21) and up, and iOS, using the appropriate USB 'on-the-go' adapter or the Apple camera connection kit.
 
The catch is that mobile devices are not able to supply enough power to MIYO via USB, so you have to use a powered USB hub, power bank, or a Y cable that let's you get power from your device's power supply (ie; iPhone charger, etc). So while it will work, we don't think it's an elegant solution for listening/recording with a smartphone or tablet.

@alexseiji: Yes, I'm using mine that way right now. The output level will come in lower than typical +4dBu line level gear (MIYO was designed for headphones first and foremost), maybe 6dB lower, but it sounds really great. And testing with line input loads has gone really well so far, as well.
 
@GinGinster: Thanks for your support – we're working very hard to get MIYO to our backers ASAP and in the best possible shape we can.
 
@freethot: Based on component choices and specs, I would expect MIYO to be a noticeable improvement. However, audio devices are surely not the sum of their parts, and the importance of specs pales in comparison to how it sounds to you specifically. In the end, it's always best to hear for yourself and decide what you like better.

Hey everyone, just wanted to let you know MIYO is available and shipping now. We've just changed our warranty to a Lifetime policy to better reflect our confidence in the product, and also offer a no questions asked 15-day return policy. Lastly, all MIYO owners now get a 90-day extended trial of TIDAL Hi-fi (the lossless tier).
 
If you have any questions, we're here!
