Picked up the packaging from our local letterpress printer - these guys are artists! It's like going back into the 1950's but using modern computer based files instead of letterset. The Heidelberg presses with black and chrome accents are amazing to look at - the smell of ink in the air makes it even better.

We are now waiting for the PC board assembly to be completed (next week) and cases to arrive (2-3 weeks) and then we are ready to do final assembly and ship. If everything goes smoothly, we may be able to ship sooner than May 1st.

I have attached a few images for you guys to enjoy.

Letterpress plates:


The presses:


Hand stamping the serial numbers:


As you can see care is taken with each unit down to the packaging you'll probably throw away.

Feels good bringing back manufacturing to the U.S.A. (in a very small, but hopefully, impactful way biggrin.gif)

We have a few units available for press review! Not sure anyone reading this thread knows anyone that does product reviews for the AVS Forum or other publications and would be interested in reviewing Myro:Air -- have them contact me! We are ahead of schedule barring any issues with the cases (arriving next Wednesday), we will begin shipping the pre-orders a couple weeks earlier than planned!

Another respectable forum I would suggest is the Home Theater Shack forum.

As we prepare to start shipping the first units -- we can begin to work on some other features for Myro:Air.

Here are a few features that are on our roadmap:
  • iOS app used to configure and control Myro:Air
  • IP based control protocol
  • cover art (RS-232 event would point to http:// resource on Myro:Air)
  • Pandora

What do you think? What else should we add? Thanks for the feedback!

Streaming Services we can support are:
- SiriusXM
- Spotify
- Pandora
- LastFM Radio
- Rhapsody

Ideally we'd love to support all but each requires us to engage with them (agreements) separately and takes time so I'd like to prioritize based on which ones people use more. I personally use Pandora and Rhapsody.

Maybe I should start a poll?

So we've shipped many units out and most should have arrived by now. I'd love to get some feedback -- anyone on AVS forum that has received a Myro:Air? For fun, post your serial number -- that's one of the unique and "exclusive" qualities of Myro:Air biggrin.gif

Here is a video review of Myro:Air by Revision3's Tekzilla Bites. They have a critical ear for audio and we're glad we were able to satisfy them.

I love Tekzilla, but he was talking so fast and always kept his eye sight straight, which made it seem like he was reading what he was saying from a board or something. biggrin.gif

Since my first generation Airport Express recently gave up, I've been looking for a high-end alternative to stream my music from my laptop to my stereo amplifier.
First I stumbled upon the Arcam Airdac and later I came across the Myro Air solution.


I have a few questions and hope to find some answers in making me decide which one to get:


1) Has anyone listened to a direct comparison of both the Arcam Airdac and the Myro Air and what was the result?
2) From the Arcam Airdac I have read that the sound is great, even with lesser quality sources like mp3 because it seems to be very "forgiving" (In my case a plus, because girlfriend plays lesser quality files). Is the Myro Air also forgiving like that?
3) The Arcam Airdac can play 24-bit 96khz music files through UPNP (Airplay is restricted to 16-bit 48khz). Can I also stream 24-bit 96khz music files from my laptop to the Myro Air through UPNP? The Wolfson WM8741 DAC seems to support up to 24-bit 192khz but the following page mentiones only support for 16 bit for the Myro Air: http://www.myrocontrol.com/forum/ind...19093#msg19093
4) Which Windows or Linux applications can be used to stream music through UPNP to the Myro Air?


For the rest the appearance of the Myro Air is amazing, I love the wood and vintage plate in front, in that aspect it's certainly a winner.
What I do miss in the Myro Air is a digital input (Toslink/SPDIF) to which I for example can connect my TV digital output. The Arcam Airdac has a huge advantage in providing these digital inputs.
What would make the Myro Air even more appealing is if it would have wifi/routing/printserver functionality like the Apple Airport Express.


Well this is going to be a tough decision even as the Arcam Airdac is available here in Europe at Amazon at a lower price then the Myro Air.

Yes. That is the beauty of a great DAC and output stage!

You can use any UPnP app, I love the BubbleUPnP and Linn (Kinsky).

Nice! We're receiving great feedback on the overall looks and quality -- this can be very subjective and we're happy people are loving it!

Here's some press from uncrate: http://uncrate.com/stuff/myro-air/

I can see the digital input, but we provide streaming and charging of an iPad/iPhone/iPod via USB as well as RS232 support for home automation systems. Our feeling was that having to "switch" inputs with no metadata would defeat the purpose of Myro:Air. But I can see how it could be a nice feature to have.

Hello Mavromatis,

Thank you for your reply.

The answer to my question 3 still leaves me a bit confused as I allready read that page with supported formats (these were also on the webpage that I listed at question 3)
On that page the bitrate for almost every format that the Myro support is listed as 16 bit.
That is somewhat peculiar as the Wolfson WM8741 DAC supports a bitrate of 24 bit or even 32 bit.

See: http://www.wolfsonmicro.com/media/76428/WM8741.pdf
PCM Mode
Sampling frequency: 32kHz to 192kHz Input data word length support: 16 to 32-bit
Supports all standard audio interface formats

So why wouldn't the Myro Air be able to support 24 bit through UPNP then? (In comparison the Airdac does support 24 bit through UPNP, so it should be possible)
As I intend to play 24 bit Flac files from my laptop, 24 bit support through UPNP is an important criteria for me (and probably also for a lot of other audiophiles the Myro Air is intended for).

Sorry, that list wasn't updated. The final release builds of Myro:Air support both 16 bit and 24 bit FLAC via UPNP. Let me know if you have any other questions.

pardon by ignorance, but what's the advantage of the my:ro over my current configuration... is it the ability to connect into other home automation products?

macbookpro -> appletv -> bitfrost schiit dac -> preamp -> amp

i use itunes remote to control the music (or control it from my laptop itself).

best,

justin

Hi Justin, in your case, the DAC and audio output stage will be different between the two devices.

We use the Wolfson WM8741 DAC, TI OPA2365 Opamp, Wima & Nichicon Black audio capacitors.

Also, correct, a difference between the two setups is the integration and feedback you can get for automation systems and plug & play capabilities for Russound RNET based whole house audio controllers.

Two months ago I decided to buy the Myro Air after having informed if the device did support streaming of 24 bit 96/192khz FLAC files through UPNP which was confirmed to me by Mavromatis.
1,5 months ago I received the Myro Air and I ran into two problems, which I reported rightaway to Mavromatis:

1) The Myro Air only supports 24bit 44khz FLAC files, it doesn support streaming 24 bit 96/192khz FLAC files through UPNP
2) The cord of the Power Adapter was broken and the power to the Myro Air kept getting cut off when the cord wasn't exactly in a right position.

One month ago after some e-mailing I was promised:

1) That a new major firmware that would support 24bit 96/192khz FLAC files would be released soon, it was in QA.
2) A new power adapter would be shipped right away

And now one month later still no sound of any new firmware and also did not receive any new power adapter until now.
Not happy to say the least!!!!


Another problem which I ran into was that the Linux Pulseaudio soundsystem only supported Airplay via TCP and new devices like the Myro Air only support the new Airplay version via UDP.
Fortunately a fork of Pulseaudio was released this month that finally does have proper support for Airplay over UDP
I've tested it and it works great, so now I can play all the sound of my laptop's soundcard through the Myro Air including the Youtube videos from my browser.
For anyone that wants to use Airplay on Linux, just folllow below information:

Installation instuctions PulseAudio Raop2-v2: http://hfujita.github.io/pulseaudio-raop2/

Hi Morgain,

Sorry you are experiencing issues. As with all our products we stand behind them. You can return your unit if you are unhappy with it -- no questions asked. However, we're here to help you through any issues you may experience. Responses inline.

We've been testing this and are having a hard time experiencing the issue you have. FLAC files and UPNP servers are all over the board. We have a ticket open with our module supplier and they have yet to explain to us if this is an issue.

The power supplies we use are these from our supplier Digikey: http://www.digikey.com/product-searc...s=T1096-P5P-ND

They should be high-quality, UL listed and other certifications, world power supplies -- not cheap. Your unit is under warranty and I have sent a replacement.

We have a new build that is in QA that also provides more functionality, however, we are holding it to try to verify and solve your issue.

I shipped you a new power supply (we are based in the USA) using US Mail, you are International. I'm surprised you haven't received it -- I can send you another one no worries.

I understand your frustration, but understand you are a top priority. We are small company and are doing our best to provide you top end service. However, we are at the mercy of a bigger company that provides us with the Apple certifiable components/modules -- they are not as fast/responsive as we'd like them to be.

As for the power supply issue -- again, you should have received it by now. Contact me again to verify I have the correct address.

I just wish you would have contacted us directly so we could help address your frustration as our intent is to have happy customers and believe me, I want you to experience the best possible sound! I hope you can see that I'm here to help resolve your issues. That said, if you are completely unsatisfied, ship the unit back and I'll issue you a refund.

Cheers!

I can understand the slow response from suppliers, I know what a hassle it can be to make them live up to their promises in time as I've had my own share of that kind of situations with suppliers.
I also understand that as a small company it's harder to get them running for you and I do appreciate the effort a smaller company as yours does to put something special like the Myro Air on the table.
But then it's extra important to keep an eye on after sales support and not keeping your customers in the dark for a long time.
I have to admit Myro Control has been very prompt with answering support e-mails and I can live with waiting a bit for a firmware fix for the UPnP issues that I experience.
But almost 2 months messing with a device that shuts down each day because of a broken power adapter gets quite annoying over time. It's that I don't want to risk ruining the device then otherwise I would have looked for some generic replacement adapter in the neighborhood. That's the part where I expect Myro Control to be prompt and make sure it get replaced quickly. I have never been able to track the replacement power adapter you claim to have send, cause I didn't get a tracking number.

Considering the UPnP issues I experience you mention that you have a hard time experiencing the same issues. Do you mean that you cannot reproduce them with the 24 bit 88/96/192 khz FLAC sample files I provided you?

I tested these files with the following setups in every combination

DLNA/UPnP renderer:
Myro Air

DLNA/UPnP media server:
Plex Media Server (both Windows 7 64-bit and Centos 7 64-bit Linux, both on different pc's)
Serviio (both Windows 7 64-bit and Centos 7 64-bit Linux, both on different pc's)
TVMOBiLi (both Windows 7 64-bit and Centos 7 64-bit Linux, both on different pc's)

DLNA/UPnP control point:
Linn Kinsky (both Windows 7 64-bit and iPhone IOS 7)
GUPNP (Centos 7 64-bit Linux)

  • Also I discovered that using the above DLNA/UPnP solutions it's not possible to "pause" streaming of a (16-bit) FLAC file, then streaming starts all over at the beginning of the song.
  • Same for moving forward or backwards within a (16-bit) FLAC track, that just makes the song start over at the very beginning again.
  • I don't experience these two issues streaming MP3 files over UPnP
  • I experience also an issue using DLNA/UPnP when manually changing to another MP3 or FLAC track, the new track starts playing 1 second and then starts over at the beginning of the song and after that keeps playing fine till the end of the song. This happens al the time while streaming through UPnP.

So to wrap it up:
Myro Air works for me perfectly using Airplay with no problems at all
Myro Air works fine for me streaming mp3 files through DLNA/UPnP
But in above configurations I do experience mentioned UPnP/FLAC related issues and the issue with 24-bit 88/96/192khz tracks through DLNA/UPnP
I'm eagerly waiting for the faulty power adapter to be replaced, that's my biggest burden at the moment for almost 2 months now.

I also understand that as a small company it's harder to get them running for you and I do appreciate the effort a smaller company as yours does to put something special like the Myro Air on the table.
But then it's extra important to keep an eye on after sales support and not keeping your customers in the dark for a long time.
I have to admit Myro Control has been very prompt with answering support e-mails and I can live with waiting a bit for a firmware fix for the UPnP issues that I experience.
But almost 2 months messing with a device that shuts down each day because of a broken power adapter gets quite annoying over time. It's that I don't want to risk ruining the device then otherwise I would have looked for some generic replacement adapter in the neighborhood. That's the part where I expect Myro Control to be prompt and make sure it get replaced quickly. I have never been able to track the replacement power adapter you claim to have send, cause I didn't get a tracking number.

Considering the UPnP issues I experience you mention that you have a hard time experiencing the same issues. Do you mean that you cannot reproduce them with the 24 bit 88/96/192 khz FLAC sample files I provided you?

I tested these files with the following setups in every combination

DLNA/UPnP renderer:
Myro Air

DLNA/UPnP media server:
Plex Media Server (both Windows 7 64-bit and Centos 7 64-bit Linux, both on different pc's)
Serviio (both Windows 7 64-bit and Centos 7 64-bit Linux, both on different pc's)
TVMOBiLi (both Windows 7 64-bit and Centos 7 64-bit Linux, both on different pc's)

DLNA/UPnP control point:
Linn Kinsky (both Windows 7 64-bit and iPhone IOS 7)
GUPNP (Centos 7 64-bit Linux)

  • Also I discovered that using the above DLNA/UPnP solutions it's not possible to "pause" streaming of a (16-bit) FLAC file, then streaming starts all over at the beginning of the song.
  • Same for moving forward or backwards within a (16-bit) FLAC track, that just makes the song start over at the very beginning again.
  • I don't experience these two issues streaming MP3 files over UPnP
  • I experience also an issue using DLNA/UPnP when manually changing to another MP3 or FLAC track, the new track starts playing 1 second and then starts over at the beginning of the song and after that keeps playing fine till the end of the song. This happens al the time while streaming through UPnP.

So to wrap it up:
Myro Air works for me perfectly using Airplay with no problems at all
Myro Air works fine for me streaming mp3 files through DLNA/UPnP
But in above configurations I do experience mentioned UPnP/FLAC related issues and the issue with 24-bit 88/96/192khz tracks through DLNA/UPnP
I'm eagerly waiting for the faulty power adapter to be replaced, that's my biggest burden at the moment for almost 2 months now.
Hi again,

Will try to repro your FLAC issues -- thanks for providing a breakdown of software used.

As for the power supply, I shipped it out using US Mail (Regular). I can reship another unit as it should have been received by now. We rarely ship US Mail (Regular) but since you are international we chose that route -- perhaps it got lost or mis-delivered. I will ship the replacement using tracking this time.

Please create a support ticket again with your shipping address and I'll get another power supply out to you.

Thanks,
Danny
